MICRO SURFACING
335-1 Description.
Construct a micro surfacing pavement with the type of mixture specified in the Contract
Documents. Micro surfacing is a mixture of polymer -modified emulsified asphalt, mineral
aggregate, mineral filler, water, and other additives, properly proportioned, mixed and spread on
a paved surface.
The mix shall be capable of being spread in variable thickness cross-sections (wedges, ruts,
scratch courses and surfaces) which, after curing and initial traffic consolidation, resists
compaction throughout the entire design tolerance range of asphalt binder content and variable
thickness to be encountered. The end product shall maintain a skid -resistant surface in variable
thick sections throughout the service life of the micro surfacing.
18
The mix shall be a quick -traffic system that will be able to accept straight rolling traffic one hour
after application.
335-2 Materials.
335-2.1 Emulsified Asphalt:
335-2.1.1 General Requirements:
Provide a quick -traffic, polymer -modified emulsified asphalt conforming to the requirements
specified in AASHTO M 208 for CSS-lh as listed in Table 335-1. The cement mixing test shall
be waived for this product.
The polymer material shall be co -milled into the asphalt or added to the emulsifier solution prior
to the emulsification process. The amount of polymer modifier shall not be less than 3.0%
polymer solids based on the asphalt content (by weight) and will be certified by the emulsified
asphalt supplier.
The Engineer may waive the five-day settlement test, provided job -stored emulsified asphalt is
used within 36 hours from the time of the shipment or the stored material has had additional
emulsified asphalt blended into it prior to use.
335-2.1.2 Quality Tests:
The emulsified asphalt, and emulsified asphalt residue, shall meet the requirements of AASHTO
M 208 for CSS -]h, with the following additions:

335-2.1.3 Sampling, Certification, and Verification:
For the first load of emulsified asphalt produced for the project, the supplier shall submit a
sample to the Engineer for testing before use. A pretest number will then be assigned by the
Engineer, and the pretest number shall be furnished with all emulsified asphalt delivered to the
project.
At any time during application, the Engineer may sample and test all subsequent loads of
emulsified asphalt delivered to the project to verify and determine compliance with specification
requirements. Where these tests identify material outside specification requirements, the
Engineer may require the supplier to cease shipment of that pre -tested product. Further shipment
of that pre -tested product to the owning agency's projects will remain suspended until the cause
of the problem is evaluated and corrected by the supplier to the satisfaction of the Engineer.
19
335-2.2 Aggregate:
335-2.2.1 General:
Use an aggregate consisting of 100% crushed stone. The aggregate shall be a crashed stone such
as granite, slag, limestone, chat, or other high-quality aggregate, or a combination thereof. To
assure the material is 100 percent crushed, the parent aggregate will be larger than the largest
stone in the gradation used. Use aggregate source(s) from the list of aggregates available on the
Florida Department of Transportation's website and also meeting the requirements of this
specification. The URL for obtaining the list of aggregates is:
ftp://ftp.dot.state.fl.us/fdot/smo/website/sources/frictioncourse.pdf .
335-2.2.2 Aggregate Quality Tests:
In addition to the requirements of FDOT Standard Specification Sections 901 and 902, meet the
minimum aggregate requirements of Table 335-2.

If the average of the five gradation tests is within the stockpile tolerances shown in Table 335-3,
Column III for all of the sieve sizes, then the stockpile is accepted. If the average of the five
gradation tests is not within the stockpile tolerances shown in Table 335-3, Column 111, for any
sieve size, remove the stockpiled material and replace it with new aggregate or blend other
aggregate sources with the stockpiled material. Aggregates used in blending must meet the
quality tests shown in Table 335-2 before blending and must be blended in a manner to produce a
consistent gradation and sand equivalent value. If new aggregate is obtained or blending of
aggregates is performed resulting in an aggregate that is not represented by the mix design,
submit a new mix design to the Engineer for approval prior to production of the mix.
The Engineer may obtain stockpile samples at any time. If the average of five gradation tests
conducted in accordance with FM 1-T 002 is not within the gradation tolerances shown in Table
335-3, Column III for any sieve size, cease production until the problem is corrected to the
satisfaction of the Engineer.
Screen all stockpiled aggregates at the stockpile area prior to delivery to the paving machine to
remove oversize material and non -desirable particles.
335-2.3 Mineral Filler:
If mineral filler is utilized in the mix design, use non air -entrained Portland cement or hydrated
lime that is free from lumps. The Engineer will accept the mineral filler by visual inspection.
The type and amount of mineral filler shall be determined by a laboratory mix design and will be
considered as part of the aggregate gradation. An increase or decrease of less than one percent
mineral filler may be permitted during production if it is found to result in better consistency or
set times. Any changes to the percentage of mineral filler must meet the requirements of Table
335-5.
335-2.4 Water:
Utilize water that is potable and free of harmful soluble salts, reactive chemicals, or any other
contaminants.
335-2.5 Additives:
Additives may be added to the mixture or any of the component materials to provide control of
quick -trafficking properties. The additives to be used should be indicated on the mix design and
be compatible with the other components of the mix.
335-2.6 Crack Filler:
Utilize a crack filler meeting the material requirements of the crack sealing specification in this
RFP.
335-3 Mix Design.
Before work begins, the Contractor shall submit a mix design to the Engineer. The mix design
must have an aggregate source used on five (5) similar projects and have been developed using
the specific materials to be used on the project. The mix design shall be developed by an
21
independent, accredited laboratory with no affiliation to the emulsion supplier and is endorsed by
the International Slurry Surfacing Association (ISSA) and has experience in designing micro
surfacing mixtures.
Submit the proposed mix design with supporting test data indicating compliance with all mix
design criteria. Allow the Engineer a maximum of two weeks to either conditionally verify or
reject the mix design.
Meet the requirements provided in Table 335-4. After the mix design has been approved, no
substitutions to the mix design will be permitted, unless approved by the Engineer. The Engineer
will consider inadequate field performance of a mix as sufficient evidence that the properties of
the mix related to the mix design have changed, and the Engineer will no longer allow the use of
the mix design. The project will be stopped until it is demonstrated that those properties, or
issues, have been sufficiently addressed.

quantity for the job or designated parts of the job.
3354 Equipment.
335-4.1 General:
Maintain all equipment, tools, and machines used in the performance of this work in satisfactory
working condition at all times to ensure a high-quality product.
3354.2 Miring Equipment:
Use a machine specifically designed and manufactured to place micro surfacing. Truck mounted
and self -loading continuous machines are acceptable. Mix the material with an automatic -
sequenced, self-propelled micro surfacing mixing machine. It shall be a continuous -flow mixing
unit able to accurately deliver and proportion the mix components through a revolving multi -
blade, double -shafted mixer and to discharge the mixed product on a continuous -flow basis. The
machine shall have sufficient storage capacity for all mix components to maintain an adequate
supply to the proportioning controls. Four truck mounted machines of 12 cubic yard capacity, or
larger, will be required for all projects or roads one half mile or less in length.
Self -loading continuous machines shall be capable of loading materials while continuing to lay
micro surfacing, thereby minimizing construction joints. Two self -loading machines may be
required on all projects or roads greater than one half mile in length. Self -loading continuous
machines shall be equipped to allow the operator to have full control of the forward and reverse
speeds during applications of the micro surfacing material and shall be equipped with opposite -
side driver stations to assist in alignment. The self -loading device, opposite -side driver stations,
and forward and reverse speed controls shall be original equipment -manufacturer design.
335-0.3 Proportioning Device:
Provide and properly mark individual volume or weight controls for proportioning each material
to be added to the mix (i.e., aggregate, mineral filler, emulsified asphalt, additives, and water).
335-4.4 Spreading Equipment:
Agitate and spread the mixture uniformly in the spreader box by means of twin -shafted paddles
or spiral augers fixed in the spreader box. Provide a front seal to ensure no loss of the mixture at
the road contact point. The rear seal shall act as a final strike -off and shall be adjustable. The
spreader box and rear strike -off shall be so designed and operated that a uniform consistency is
achieved and a free flow of material is provided to the rear strike -off. The spreader box shall
have suitable means to hydraulically adjust the box width automatically while traveling behind
the mixing unit, and be able to side shift the box to compensate for variations in the pavement
geometry.
23
335-4.4.1 Secondary Strike -off:
Provide a secondary strike -off to improve surface texture. The secondary strike -off shall have
the same adjustments as the spreader box. No burlap drags will be permitted on the final
applications or hand work.
335-4.4.2 Rut -filling Equipment:
When required by the Contract Documents, micro surfacing material may be used to fill ruts,
utility cuts, depressions in the existing surface, etc. When rutting or deformation is less than 1/2
inch, a full width scratch course may be applied with the spreader box using a metal or stiff
rubber strike -off. Ruts of 1/2 inch or greater in depth shall be filled independently with a rut -
filling box, either five or six feet in width. Ruts that are in excess of 1 1/2 inch in depth may
require multiple applications with the rut -filling box to restore the cross-section.
When a rut box is used, emulsified asphalt content may be reduced by 0.5% of the mix design
target. Any reduction of emulsified asphalt content must be within the tolerance of the job mix
formulation listed in the mix design. Material placed with the rut -filling box shall have a 1/4
inch crown to allow for traffic consolidation. Before placing subsequent lifts, allow all rut -filling
material to cure under traffic for at least 24 hours.
335-4.5 Auxiliary Equipment:
Provide suitable surface preparation equipment, traffic control equipment, hand tools, and any
other support and safety equipment necessary to perform the work.
335-5 Calibration.
Calibrate each mixing unit to be used in the performance of the work in the presence of the
Engineer prior to the start of construction. Previous calibration documentation covering the
exact materials to be used may be acceptable, provided that no more than 60 days have lapsed.
Document the individual calibration of each material at various settings, which can be related to
the machine metering devices. Do not utilize any mixing unit on the project until the calibration
has been completed and approved by the Engineer. Any component replacement affecting
material proportioning requires that the machine be recalibrated. No machine will be allowed to
work on the project until the calibration has been completed and accepted.
335-6 Weather Limitations.
Do not apply micro surfacing if either the pavement or air temperature is below 50°F. Do not
apply micro surfacing when there is the possibility that the finished product will freeze within 24
hours. Do not apply micro surfacing in the rain or when there is standing water on the pavement.
The mixture shall not be applied when weather conditions prevent opening to traffic within a
reasonable amount of time, as determined by the Engineer.
335-7 Surface Preparation.
24
335-7.1 General
Remove any thermoplastic striping materials and retro -reflective pavement markers in the areas
to be micro surfaced. Provide temporary striping as necessary to comply with Contract
Documents. Immediately prior to applying the micro surfacing, clear the surface of all loose
material, silt spots, vegetation, and other material that will negatively affect the quality of the
micro surfacing, utilizing any standard cleaning method. If water is used for cleaning, allow any
unsealed cracks to dry thoroughly before applying micro surfacing. Protect manholes, valve
boxes, drop inlets and other service entrances from the micro surfacing mixture by a suitable
method. The Engineer will approve the surface preparation prior to micro surfacing. No loose
aggregate, either spilled from the lay -down machine or existing on the road, will be permitted.
335-7.3 Rumble Strips:
Where shoulders are not to be micro surfaced, prevent material from being applied to or entering
any rumble strip depressions. If necessary, remove any material that enters the depressions.
When rumble strips are to be micro surfaced, place a scratch course to fill the depressions prior
to placing the final surface course.
335-7.4 Tack Coat
Place a tack coat on all collector roads prior to constructing a micro surfacing course. A tack coat
is not required on residential roads or between the leveling (scratch) course and the surface
course provided the surface course is placed within 30 days of the leveling (scratch) course. If
required, the tack coat should be type SS, type CSS, or the micro surfacing emulsified asphalt. It
may consist of one part emulsified asphalt to three parts water and should be applied with a
standard distributor. The distributor shall be capable of applying the tack evenly at a rate of
0.05-0.15 gal/yd2.
335-8 Application.
335-8.1 General:
Pre -wet the surface by fogging ahead of the spreader box with water. Adjust the rate of
application of the fog spray to suit temperatures, surface texture, humidity, and dryness of the
pavement.
The micro surfacing shall be of the desired consistency upon leaving the mixer. Cary a
sufficient amount of material in all parts of the spreader box at all times so that complete
coverage is obtained. Avoid overloading of the spreader box. Do not allow lumping, balling, or
unmixed aggregate in the micro surfacing mixture.
Do not leave streaks, such as those caused by oversized aggregate, in the finished surface. If
excess streaking develops, stop production until the situation has been corrected. Excessive
streaking is defined as more than four drag marks greater than 1/2 inch wide and 4 inches long,
or 1 inch wide and 3 inches long, in any 30 yd2 area. Do not permit transverse ripples or
longitudinal streaks of 1/4 inch in depth or greater, when measured by placing a 10 -foot straight
edge over the surface.
25
335-8.2 Rate of Application.
The average application rate shall be in accordance with Table 335-6, unless otherwise specified
in the Contract Documents. Full width application rates must be maintained within t 2 lbs/yd-7
of the specified rate. Application rates are based upon the weight of dry aggregate in the
mixture. The maximum thickness of any single layer of micro surfacing at the edge of the
pavement shall be 1/4 inch.

335-8.3 Joints:
Prevent excessive buildup, uncovered areas, or unsightly appearance on longitudinal and
transverse joints. Provide suitable -width spreading equipment to produce a minimum number of
longitudinal joints throughout the project. Place longitudinal joints on lane lines, where possible.
Use half passes and odd -width passes only when absolutely necessary. Do not apply a half pass
as the last pass of any area. Do not overlap longitudinal lane line joints by more than three
inches. Do not construct joints having more than a 1/4 inch difference in elevation when
measured by placing a 10 -foot straight edge over the joint and measuring the elevation drop-off.
Construct longitudinal joints so that water is not held at the joint. Construct transverse joints at
the beginning and end project limits so that the elevation difference between the micro surfacing
and the adjacent pavement does not exceed 1/4 inch.
335-8.4 Mix Stability:
Produce a micro surfacing mixture that possesses sufficient stability so that premature breaking
of the material in the spreader box does not occur. The mixture shall be homogeneous during
and following mixing and spreading. The mixture shall be free of excess water or emulsified
asphalt and free of segregation of the emulsified asphalt and aggregate fines from the coarser
aggregate. Do not spray water directly into the spreader box while applying micro surfacing
material under any circumstances.
26
335-8.5 Handwork:
Utilize hand squeegees to provide complete and uniform coverage of micro surfaced areas that
cannot be reached with the mixing machine. Lightly dampen the area to be hand worked prior to
mix placement, if necessary. Care shall be exercised to leave no unsightly appearance from
handwork. When performing handwork, provide the same type of finish as that applied by the
spreader box.
335-8.6 Lines:

scales, which is equipped with an automatic recordation system that is approved by the Engineer. Use scales
of the type that directly indicates the total weight of the loaded truck. Use scales meeting the requirements
for accuracy, condition, etc., of the Bureau of Weights and Measures of the Florida Department of
Agriculture, and re -certify such fact every six months, either by the Bureau of Weights and Measures or by a
registered scale technician.
M
320-3.2.2 Electronic Weigh System on Hoppers Beneath a Surge or Storage Bin: Provide an electronic
weigh system on the hopper (hopper scales or load cells) beneath the surge or storage bin, which is equipped
with an automatic recordation system approved by the Engineer.
320-3.2.3 Automatic Batch Plants with Printout: For batch plants, provide an approved automatic printer
system which will print the individual or cumulative weights of aggregate and liquid asphalt delivered to the
pugmill and the total net weight of the asphalt mix measured by hopper scales or load cell type scales. Use

have been approved by the Engineer.
320-3.2.4 Monthly Electronic Weigh System Comparison Checks: Check the accuracy of the electronic
weighingsystem at the commencement of production and thereafter at least every 30 days during production
by one of the following two methods and maintain a record of the weights in the Scale Check Worksheet.
320-3.2.4.1. Electronic Weigh System on Truck Scales:
1. The Engineer will randomly select a loaded track of asphalt mix, a loaded aggregate haul truck, or
another vehicle type approved by the Engineer and record the truck number and gross weight from the
Contractor's delivery ticket.
2. Weigh the selected truck on a certified track scale, which is not owned by the Contractor and
record the gross weight for the comparison check. If another certified track scale is not available, the
Engineer may permit another set of certified truck scales owned by the Contractor to be used. The Engineer
may elect to witness the scale check.
3. The gross weight of the loaded track as shown on the Contractor's delivery ticket will be
compared to the gross weight of the loaded track from the other certified truck scale. The maximum
permissible deviation is 8 pounds per ton of load, based on the certified track scale weight.
4. If the distance from the asphalt plant to the nearest certified track scale is enough for fuel
consumption to affect the accuracy of the comparison checks, a fuel adjustment may be calculated by using
the truck odometer readings for the distance measurement, and 6.1 miles per gallon for the fuel consumption
rate, and 115 ounces per gallon for fuel weight.
5. During production, when an additional certified truck scale is not available for comparison checks,
the Engineer may permit the Contractor to weigh the track on his certified scales used during production and
then weigh it on another certified track scale, as soon the other scale is available for the comparison checks.
In addition to the periodic checks as specified above, check the scales at any time the accuracy of the scales
becomes questionable. When such inaccuracy does not appear to be sufficient to seriously affect the
weighing operations, the Engineer will allow a period of two calendar days for the Contractor to conduct the
required scale check. However, in the event the indicated inaccuracy is sufficient to seriously affect the
mixture, the Engineer may require immediate shut -down until the accuracy of the scales has been checked
and necessary corrections have been made. Include the cost of all scale checks in the bid price for asphalt
concrete, at no additional cost to the Department.
320-3.2.4.2. Electronic Weigh System on Hoppers Beneath a Surge or Storage Bin and Automatic
Batch Plants with Printout:
1. The Engineer will randomly select a loaded truck of asphalt mix and record the track number, and
the net weight of the asphalt mix from the Contractor's delivery ticket.
2. Weigh the selected truck on a certified track scale, which is not owned by the Contractor and
record the gross weight for the comparison check. If another certified track scale is not available, the
Engineer may permit another set of certified truck scales owned by the Contractor to be used. The Engineer
may elect to witness the scale check.
3. Deliver the asphalt mix to the project, and then weigh the selected empty truck on the same
certified track scales. Record the tare weight of the truck.
0
4. Compare the net weight of the asphalt mix from the delivery ticket to the calculated net weight of
the asphalt mix as determined by the certified truck scale weights. The maximum permissible deviation is 8
pounds per ton of load, based on the certified truck scale weight.
5. Use the fuel adjustment as specified in 320-3.2.4.1(4), when the distance from the asphalt plant to
the nearest certified truck scale is enough for fuel consumption to affect the accuracy of the comparison
checks.
6. During production, when an additional certified truck scale is not available for comparison checks,
the Engineer may permit the Contractor to load a truck with aggregate from the pugmill, surge or storage bin,
and follow the above procedures to conduct the comparison checks as soon as certified truck scale is
available. If the check shows a greater difference than the tolerance specified above, then recheck on a
second set of certified scales. If the check and recheck indicate that the printed weight is out of tolerance,
have a certified scale technician check the electronic weigh system and certify the accuracy of the printer.
While the system is out of tolerance and before its adjustment, the Engineer may allow the Contractor to
continue production only if provisions are made to use a set of certified truck scales to determine the truck
weights.
320-3.3 Asphalt Binder: Meet the following requirements:
320-3.3.1 Transportation: Deliver the asphalt binder to the asphalt plant at a temperature not to exceed
370°F, and equip the transport tanks with sampling and temperature sensing devices meeting the
requirements of 300-3.2.
320-3.3.2 Storage: Equip asphalt binder storage tanks to heat the liquid asphalt binder to the temperatures
required for the various mixtures. Heat the material in such a manner that no flame comes in contact with the
binder. Heat or insulate all pipe lines and fittings. Use a circulating system of adequate size to ensure proper
and continuous circulation during the entire operating period. Locate a thermometer, reading from 200 to
400°F, either in the storage tank or in the asphalt binder feed line. Maintain the asphalt binder in storage
within a range of 230 to 370°F in advance of mixing operations. Locate a sampling device on the discharge
piping exiting the storage tank or at a location as approved by the Engineer. Provide a metal can of one quart
capacity for binder sampling at the request of the Engineer.
320-3.4 Aggregate: Meet the following requirements:
320-3.4.1 Stockpiles: Place each aggregate component in an individual stockpile, and separate each from the
adjacent stockpiles, either by space or by a system of bulkheads. Prevent the intermingling of different
materials in stockpiles at all times. Identify each stockpile, including RAP, as shown on the mix design.
Form and maintain stockpiles in a manner that will prevent segregation. If a stockpile is determined to be
segregated, discontinue the use of the material on the project until the appropriate actions have been taken to
correct the problem.
320-3.4.2 Blending of Aggregates: Stockpile all aggregates prior to blending or placing in the cold feed
bins. If mineral filler or hydrated lime is required in the mix, feed or weigh it in separately from the other
aggregates.
320-3.4.2.1 Cold Feed Bin: Provide a separate cold feed bin for each component of the fine and coarse
aggregate required by the mix design. Equip the cold feed bins with accurate mechanical means for feeding
the aggregate uniformly into the dryer in the proportions required for the finished mix to maintain uniform
production and temperature. When using RAP as a component material, prevent any oversized RAP from
being incorporated into the completed mixture by the use of a grizzly or grid over the RAP bin; in-line roller
or impact crusher, screen; or other suitable means. If oversized RAP material appears in the completed
7
recycled mix, take the appropriate corrective action immediately. If the appropriate corrective actions are not
immediately taken, stop plant operations. Use separate bin compartments in the cold aggregate feeder that
are constructed to prevent any spilling or leakage of aggregate from one cold feed bin to another. Ensure that
each cold feed bin compartment has the capacity and design to permit a uniform flow of aggregates. Mount
all cold feed bin compartments over a feeder of uniform speed, which will deliver the specified proportions
of the separate aggregates to the drier at all times. If necessary, equip the cold feed bins with vibrators to
ensure a uniform flow of the aggregates at all times.
320-3.4.2.2 Gates and Feeder Belts: Provide each cold feed bin compartment with a gate and feeder belt,
both of which are adjustable. to assure the aggregate is proportioned to meet the requirements of the mix
design.
320-3.4.3 Screening Unit: Remove any oversized pieces of aggregate by the use of a scalping screen. Do not
return this oversized material to the stockpile for reuse unless it has been crushed and reprocessed into sizes
that will pass the scalping screen. Ensure that the quantity of aggregates being discharged onto the screens
does not exceed the capacity of the screens to actually separate the aggregates into the required sizes.
320-3.5 Dryer: Provide a dryer of satisfactory design for heating and drying the aggregate. Use a dryer
capable of heating the aggregate to within the specified temperature range for any mix, and equip the dryer
with an electric pyrometer placed at the discharge chute to automatically register the temperature of the
heated aggregates.
320-3.6 Asphalt Binder Control Unit: Provide a satisfactory means, either by weighing, metering, or
volumetric measuring, to obtain the proper amount of asphalt binder material in the mix, within the tolerance
specified for the mix design.
320-3.7 Contractor's Responsibilities: Acceptance of any automatic delivery ticket printout, electronic
weight delivery ticket, other evidence of weight of the materials or approval of any particular type of
material or production method will not constitute agreement by the Department that such matters are in
accordance with the Contract Documents and it shall be the Contractor's responsibility to ensure that the
materials delivered to the project are in accordance with the Contract Documents.
320-4 Additional Requirements for Batch Plants.
320-4.1 Heating and Drying: Heat and dry the aggregate before screening. Control the temperature of the
aggregate so the temperature of the completed mixture at the plant falls within the permissible range allowed
by this Section.
320-4.2 Gradation Unit: Provide plant screens capable of separating the fine and coarse aggregates and of
further separating the coarse aggregate into specific sizes. In addition, equip the gradation unit with a
scalpingscreen to restrict the maximum size of the aggregates. In the event that the plant is equipped with
cold feed bins that are capable of adequately controlling the gradation of the mixture, the use of plant screens
is optional.
320-4.3 Hot Bins: Provide storagebins of sufficient capacity to supply the mixer when it is operating at full
capacity. Provide hot bins with divided compartments to ensure separate and adequate storage of the
appropriate fractions of the aggregate. Equip each compartment with an overflow chute of suitable size and
location to prevent any backing up of material into other bins.
320-4.4 Weigh Box or Hopper: Equip the batch plant with a means for accurately weighing each bin size of
aggregate and the mineral filler into the weigh box or hopper.
3204.5 Pugmills: Utilize a pugmill capable of mixing the aggregate and the asphalt binder.
n
320-5 Additional Requirements for Drum Mixer Plants
320-5.1 Weight Measurements of Aggregate: Equip the plant with a weigh -in -motion scale capable of
measuring the quantity of aggregate (and RAP) entering the dryer.
320-5.2 Synchronization of Aggregate Feed and Asphalt Binder Feed: Couple the asphalt binder feed
control with the total aggregate weight device, including the RAP feed, in such a manner as to automatically
vary the asphalt binder feed rate as necessary to maintain the required proportions.
320-5.3 Hot Storage or Surge Bins: Equip the plant with either a surge bin or storage silo that is capable of
storing an adequate amount of material to assure a uniform and consistent product.
320-6 Preparation of the Mixture
320-6.1 Mixing; After the aggregate is dried and properly proportioned, mix the aggregate, along with any
other components, with the asphalt binder to produce a thoroughly and uniformly coated mixture. Do not
produce the mix by altering the component blend percentage of the RAP or sand by more than plus or minus
5.0% from the job mix formula on the approved mix design. For mix designs using fractionated RAP, the
combined blend change for all RAP components must not exceed plus or minus 5.0%. The plus or minus
5.0% maximum component change does not apply to crashed virgin aggregate components during
production.
320-6.2 Storage: If necessary, store the asphalt mixture in a surge bin or hot storage silo for a maximum of
72 hours. For FC -5 mixtures, store the asphalt mixture in a surge bin or hot storage silo for a maximum of
one hour.
320-6.3 Mix Temperature: Produce the mixture with a temperature within the master range as defined in
Table 320-2.
320-6.3.1 Test Requirements: Determine the temperature of the completed mixture using a quick -reading
thermometer through a hole in the side of the loaded truck immediately after loading. Locate a 1/4 inch hole
on both sides of the track body within the middle third of the length of the body, and at a distance from 6 to
10 inches above the surface supporting the mixture. If a track body already has a hole located in the general
vicinity of the
specified location, use this hole. At the Engineer's discretion, the Contractor may take the temperature of the
load over the top of the track in lieu of using the hole in the side of the track.
320-6.3.2 Test Frequency: The normal frequency for taking asphalt mix temperatures will be for each day,
for each design mix on the fust five loads and one out of every five loads thereafter. Take the temperature of
the asphalt mix at the plant and at the roadway before the mix is placed at the normal frequency. Record the
temperature on the front of the respective delivery ticket. The Engineer shall review the plant and roadway
temperature readings and may take additional temperature measurements at any time.
If any single load at the plant or at the roadway is within the master range shown in Table 320-2 but does not
meet the criteria shown in Table 320-3 (for single measurements or the average of five consecutive
measurements), the temperature of every load will be monitored until the temperature falls within the
specified tolerance range in Table 320-3; at this time the normal frequency may be resumed. For warm mix
asphalt, the Contractor may produce the first five loads of the production day and at other times when
ELI
approved by the Engineer, at a hot mix asphalt temperature not to exceed 330°F for purposes of heating the
asphalt paver. For this situation, the upper tolerances of Tables 320-2 and 320-3 as applied to the warm mix
asphalt mix design do not apply.
For windrow paving, in addition to the truck load temperature measurements noted above, perform windrow
temperature measurements at a frequency of one measurement per 500 feet of windrow placed. Check the
temperature of the windrow asphalt mixture using a quick -reading thermometer or directly in front of the
windrow material transfer vehicle, but not so close that paving must be stopped. Measure the temperature of
the windrow beneath the exposed surface by shoveling away a portion of the windrow and then measuring
the temperature. For windrow temperature measurements, the requirements of Table 320-2 and 320-3 apply.
320-6.3.3 Rejection Criteria: Reject any load or portion of a load of asphalt mix at the
plant or at the roadway with a temperature outside of its respective master range shown in
Table 320-2. Notify the Engineer of the rejection immediately.
Table 320-2
Mix Temperature Master Range Tolerance
Location Acceptable Temperature Tolerance
Plant Mixing Temperature t30 F
Roadway (mix in truck) Compaction Temperature t300F
Roadway (mix in windrow) Compaction Temperature +30°F, -40°F
320-7 Transportation of the Mixture.
Transport the mix in trucks of tight construction, which prevents the loss of material and the excessive loss
of heat and previously cleaned of all foreign material. After cleaning, thinly coat the inside surface of the
truck bodies with soapy water or an asphalt release agent as needed to prevent the mixture from adhering to
the beds. Do not allow excess liquid to pond in the truck body. Do not use a release agent that will
contaminate, degrade, or alter the characteristics of the asphalt mix or is hazardous or detrimental to the
environment. Petroleum derivatives (such as diesel fuel), solvents, and any product that dissolves asphalt are
prohibited. Provide each truck with a tarpaulin or other waterproof cover mounted in such a manner that it
can cover the entire load when required. When in place, overlap the waterproof cover on all sides so that it
can be tied down. Cover each load during cool and cloudy weather and at any time it appears rain is likely
during transit with a tarpaulin or waterproof cover. Cover and tie down all loads of friction course mixtures.
SECTION 327 MILLING OF EXISTING ASPHALT PAVEMENT
327-1 Description.
Remove existing asphalt concrete pavement by milling to improve the rideability and cross slope of the
finished pavement, to lower the finished grade adjacent to existing curb before resurfacing, or to completely
remove existing pavement. When milling to improve rideability, the Plans will specify an average depth of
cut. Take ownership of milled material unless directed by the City to deliver to a site designated by the City
for the City to retain ownership.
327-2 Equipment.
Provide a milling machine capable of maintaining a depth of cut and cross slope to achieve the results
specified in the Contract Documents. Use a machine with a minimum overall length (out -to -out measurement
excluding the conveyor) of 18 feet and a minimum cutting width of 6 feet.
Equip the milling machine with a built-in automatic grade control system that can control the transverse
slope and the longitudinal profile to produce the specified results.
To start the project, the Engineer will approve any commercially manufactured milling machine that meets
the above requirements. If it becomes evident after starting milling that the milling machine cannot
consistently produce the specified results, the Engineer will reject the milling machine for further use.
The Contractor may use a smaller milling machine when milling to lower the grade adjacent to existing curb
or other areas where it is impractical to use the above described equipment.
Equip the milling machine with means to effectively limit the amount of dust escaping during the removal
operation.
For complete pavement removal, the Engineer may approve the use of alternate removal and crushing
equipment instead of the equipment specified above.
327-3 Construction.
327-3.1 General: Remove the existing raised reflective pavement markers before milling. Include the cost of
removing existing pavement markers in the price for milling.
When milling to improve rideability or cross slope, remove the existing pavement to the average
depth specified in the Plans, in a manner that will restore the pavement surface to a uniform cross-section
and longitudinal profile. The Engineer may require the use of a stringline to ensure maintaining the proper
alignment.
Establish the longitudinal profile of the milled surface in accordance with the milling plans. Ensure
the final cross slope of the milled surface parallels the surface cross slope shown in the Plans or as directed
by the Engineer. Establish the cross slope of the milled surface by a second sensing device near the outside
edge of the cut or by an automatic cross slope control mechanism.
The Plans may waive the requirement of automatic grade or cross slope controls where the situation
warrants such action.
Operate the milling machine to minimize the amount of dust being emitted. The Engineer may
require prewetting of the pavement.
Provide positive drainage of the milled surface and the adjacent pavement. Perform this operation on
the same day as milling. Repave all milled surfaces no later than the day after the surface was milled.
If traffic is to be maintained on the milled surface before the placement of the new asphalt concrete,
provide suitable transitions between areas of varying thickness to create a smooth longitudinal riding surface.
Produce a pattern of striations that will provide an acceptable riding surface. The Engineer will control the
traveling speed of the milling machine to produce a texture that will provide an acceptable riding surface.
Before opening an area which has been milled to traffic, sweep the pavement with a power broom or
other approved equipment to remove, to the greatest extent practicable, fine material which will create dust
under traffic. Sweep in a manner to minimize the potential for creation of a traffic hazard and to minimize air
pollution.
Sweep the milled surface with a power broom before placing asphalt concrete.
In urban and other sensitive areas, use a street sweeper or other equipment capable of removing excess
milled materials and controlling dust. Obtain the Engineer's approval of such equipment, contingent upon its
demonstrated ability to do the work.
Perform the sweeping operation immediately after the milling operations or as directed by the
Engineer.
327-3.2 Quality Control Requirements: Furnish a four foot long electronic level accurate to 0.1 degree,
approved by the Engineer for the control of cross slope. Make this electronic level available at the jobsite at
all times during milling operations. Calibrate and compare electronic levels in accordance with 330-9.3.1 at a
minimum frequency of once per day before any milling operation.
Multiple cuts may be made to achieve the required pavement configuration or depth of cut.
T
327-3.2.1 Cross Slope Measurement: Measure the cross slope of the milled surface by placing the level at
the center of the lane and perpendicular to the roadway centerline. Record all the measurements to the
nearest 0.1 % on an approved form and submit the data to the Engineer.
327-3.2.1.1 Cross Slope Measurement Frequency:
1. Tangent Sections: Measure the cross slope at a minimum frequency of one measurement every 100
feet per lane. When the average absolute deviation is consistently within the acceptance tolerance in Table
327-1, upon approval by the Engineer, the frequency of the cross slope measurements can be reduced to one
measurement every 200 feet.
2. Superelevated Sections: Measure the cross slope every 100 feet per lane within the length of full
superelevation. For curves where the length of full superelevation is less than 250 feet, measure the cross
slope at the beginning point, midpoint, and ending point of the fully superelevated section. For transition
sections, measure the cross slope at control points identified in the Plans or, if not shown in the Plans, at a
control point at a location of 0.0% cross slope.
327-3.2.1.2 Cross Slope Deviations and Corrections: Calculate the absolute deviation of each cross slope
measurement and the average of the absolute deviations of ten consecutive cross slope measurements. The
absolute deviation is the positive value of a deviation. In superelevated sections, when the number of
measurements is less than ten, average the absolute deviation of all measurements.
If the average absolute deviation of any cross slope measurement falls outside the acceptance
tolerance shown in Table 327-1, stop the milling operations and make adjustments until the problem is
resolved to the satisfaction of the Engineer. If an individual cross slope deviation falls outside the acceptance
tolerance as shown in Table 327-1, make corrections only in the deficient area to the satisfaction of the
Engineer at no cost to the Department. For pavement with multiple cuts, the deficient areas not caused by the
final cut may be left in place upon approval of the Engineer. All milling corrections shall be completed
before placement of the asphalt course unless stated otherwise in the Plans or as determined by the Engineer.
The limits of deficient areas requiring correction may be verified and adjusted with more accurate
measurement methods, including survey instruments, upon approval of the Engineer and at no cost to the
Department.
Should the Contractor wish to have any required corrections waived, submit a request to the Engineer
for approval. The Engineer may waive the corrections at no reduction in payment if the deficiencies are
sufficiently separated so as not to significantly affect the final cross slope or project grade.
u
For intersections, tapers, crossovers, transitions at the beginning and end of the project,
bridge approaches and similar areas, adjust the cross slope to match the actual site
conditions, or as directed.
TABLE 327-1
Cross Slope Milling Acceptance Tolerance
Roadway Feature Individual Absolute Average Absolute Deviation
Deviation
Tangent section 0.4% 0.2%
(including tum lanes)
Superelevated curve 0.4% 0.2%
Shoulder 0.5% 0.5%
In the event the distance between two edges of deficient areas is less than 100 feet, the correction work
shall include the area between the deficient areas.
327-3.3 Verification: The Engineer will verify the Contractor's cross slope measurements by randomly
taking a minimum of ten cross slope measurements per lane per mile in tangent sections, at control
points in transition sections, and a minimum of three cross slope measurements in fully superelevated
sections. The Engineer will measure the cross slope of the milled surface by placing the level at the
center of the lane and perpendicular to the roadway centerline.
327-33.1 Cross Slope Deviations and Corrections:
If the average absolute deviation or an individual cross slope deviation falls outside the acceptance
tolerance in Table 327-1, immediately make a comparison check at the QC test locations to verify the
QC measurements in the section. If the comparisons are beyond the acceptable comparison tolerance in
accordance with 327-3.2, stop the milling operation until the issue is resolved to the satisfaction of the
Engineer. Correct any cross slope not meeting the individual deviation acceptance tolerance at no cost to
the Department. The Engineer reserves the right to check the cross slope of the milled surface at any
time by taking cross slope measurements at any location.
3274 Milled Surface.
Provide a milled surface with a reasonably uniform texture, within 1/4 inch of a true profile grade, and
with no deviation in excess of 1/4 inch from a straightedge applied to the pavement perpendicular to the
centerline. Ensure the variation of the longitudinal joint between multiple cut areas does not exceed 1/4
inch. The Engineer may accept areas varying from a true surface in excess of the above stated tolerance
without correction if the Engineer determines they were caused by a pre-existing condition which could
not have reasonably been corrected by the milling operations. Correct any unsuitable texture or profile,
as determined by the Engineer, at no cost to the Department.
The Engineer may require remilling of any area where a surface lamination causes a non-uniform
texture to occur.
327-5 Method of Measurement.
The quantity to be paid for will be the plan quantity area, in square yards, over which milling is
completed and accepted.
V
327-6 Basis of Payment.

listed in FDOT Design Standards as General Use Optional Base Materials) shall be placed in the excavation
uniformly and without loss or contamination. The Contractor shall correct all areas of irregular grade or deficient
thickness and shall remove and replace material contaminated with soil, organic material, or debris.
After the final pass of the reclaimer, soil shall be drawn up against the widening material to close the excavation,
and the shoulder shall be graded and compacted to produce a firm, even surface.
Additional Material: When additional material is to be added to correct cross slope deficiencies or change
elevation as directed by the engineer, approved base material (those bases listed in FDOT Design Standards as
General Use Optional Base Materials) shall be placed on the roadway prior to final pass for pulverization and
mixed uniformly with the existing material.
Pulverization: The existing pavement and base material shall be pulverized and blended to the depth required
so the entire mass of material shall be uniformly graded to the following gradation:
SIEVE SIZE _ _ PERCENT PASSING
2' 98-100
1-112" 95 I
111
Material gradation may vary due to local aggregates and conditions. Multiple passes of the reclaimer may be
necessary to achieve the required gradation.
The asphalt emulsion or asphalt and water (to produce a foamed asphalt) shall be introduced into the mix through
the reclaimer uniformly and accurately and metered such that areas are of equal consistency and moisture
content. The reclaimed material and additives shall be combined in place to meet the requirements specified in
such proportions that the reclaimed mixture is of acceptable composition and stability. Before the start and at the
end of each day's work and at any time requested, the engineer must be permitted access to the mixing
equipment in order to read the meter to verify the quantity of asphalt emulsion applied during the days work.
Field adjustments shall be made as necessary to the recommended mix design under the guidance of a
knowledgeable and competent technician or superintendent to obtain a satisfactory reclaimed mixture of
consistent composition and stability throughout the Project.
After the material has been processed, it shall be compacted to the lines, grades, and depth required. Water may
be applied to ensure optimum moisture content at the time of mixing and compaction.
Compaction: Commence rolling with self propelled rollers as required by this technical provision at the low side
of the course, except leave 3 to 6 inches from any unsupported edge or edges unrolled Initially to prevent
distortion. Density readings shall be taken by Contractor's licensed nuclear gauge operator and witnessed by the
Engineer/inspector.
Rollers shall move at a uniform speed that shall not exceed 8 km/hour (5 miles/hour). For static rollers, the drive
drum normally shall be in the forward position or nearest to the paver. Vibratory rollers shall be operated at the
speed, frequency and amplitude required to obtain the required density and prevent defects in the mat.
The number, weight and type of rollers furnished shall be sufficient to obtain the required compaction of the
reclaimed material. The field density of the compacted mixture shall be at least 94 percent of the maximum
density of laboratory specimens prepared from samples of the base material taken from the material in place. The
specimens shall be compacted in accordance with AASHTO T-180. The in-place field density shall be
determined in accordance with ASTM D 2922.
Any pavement shoving or other unacceptable displacement shall be corrected. The cause of the displacement
shall be determined and corrective action taken immediately and before continuing rolling. Care shall be
exercised in rolling the edges of the reclaimed mixture so the line and grade of the edge are maintained.
At the end of each day's production, a transverse construction joint shall be formed by a header or by cutting back
into the compacted material to form a true vertical face free of loose material. The protection provided for
construction joints shall permit the placing, spreading, and compacting of base material without injury to the work
previously laid. Where it is necessary to operate or turn any equipment on the completed base course, sufficient
protection and cover shall be provided to prevent damage to the finished surface. A supply of mats or wooden
planks shall be maintained and used as approved and directed by the Engineer.
Finishing: Finishing operations shall be completed and the base course shall conform to the required lines,
grades, and cross section. If necessary, the surface shall be lightly scarified to eliminate any imprints made by the
compacting or shaping equipment. The surface shall then be recompacted to the required density. Correct all
irregularities greater than Y=" over ten feet to the satisfaction of the engineer.
Protection and Curing: After the base course has been finished as specified herein, it shall be protected against
drying for a period of 2 to 3 days by the application of a prime coat as specified in FDOT Standard Specifications
section 300 at a rate of not less than 0.15 gal/sy. The curing method shall begin as soon as possible, but no later
than 24 hours after the completion of finishing operations. The finished base course shall be kept moist
continuously until the curing material is placed.
At the time the prime coat is applied, the surface shall be dense, free of all loose and extraneous material, and
shall contain sufficient moisture to prevent penetration of the bituminous material. Water shall be applied in
sufficient quantity to fill the surface voids immediately before the bituminous curing material is applied.
To prevent equipment from marring or damaging the completed work, protect
finished portions of base used by equipment.
Do not allow traffic on the reclaimed base until it is assured the reclaimed
base surface will not distort, shove, or ravel under the anticipated vehicular loading.
Thickness: The average thickness of the base constructed during one day shall be within 1/2 inch (12 mm) of
the thickness required, except that the thickness of any one point may be within 3/4 inch (19 mm) of that required
Where the average thickness shown by the measurements made in one day's construction is not within the
tolerance given, the Engineer shall evaluate the area and determine if, in his/her opinion, it shall be reconstructed
at the Contractor's expense or the deficiency deducted from the total material in place.

Mixture Design:
A mix design(s) conducted by an independent, accredited laboratory with no affiliation to the emulsion
supplier, using materials obtained directly from the project site and conforming to the requirements of
this Technical Specification shall be submitted to the County at the Pre -Construction Conference. Based
on RAP consistency throughout project limits, more than one mix design may be required. A traffic
control plan may be required in accordance with TP -102 for collecting materials. Mix design
formulations shall be conducted in accordance with the following guidelines:
Mix Design Procedures for CIR (Cold In-place Recycling) Material
• Sampling and Processing - Prior to materials sampling in the roadway, obtain approval from
the City. A traffic control plan may be required in accordance with TP -102 for collecting
materials. Obtain 6" minimum inside diameter cores from the areas to be recycled. If cores
show significant differences in various areas, such as different type or thickness of layers
between cores, then separate mix designs shall be performed for each of these pavement
segments. It is recommended that a minimum of one location be sampled for each 1000' in each
lane. Additionally, samples should be taken where visual differences in the pavement are
noticed. Immediately patch all core holes neatly with asphalt cold patch. Cores shall be cut in
the laboratory to the depth specified for the CIR project. Cores shall be crushed in the
laboratory.
The mix design shall be performed on this crushed sample. Gradation of the sample after
crushing shall be determined by ASTM C117 and C136 (dried at no greater than 400C). Samples
shall be prepared with a sample splitter. An alternative method is to dry, screen and recombine
the sample in the laboratory to target gradation.
• Mixing - Calculate the amount of RAP required to produce a 61.0 mm to 66.0 mm (2.4 to 2.6
inch) tall specimen by determining the maximum specific gravity of the RAP in accordance with
ASTM D2041.
Number of specimens: 4 per emulsion content for a total of 4 for long-term stability and 4 for
moisture testing for the 3 emulsion contents. Two specimens are required for Rice specific
gravity; test at the highest emulsion content in the design and back calculate for the lower
emulsion contents.
Recommended emulsion contents: 2.0%, 2.5%, 3.0%, 3.5%. Choose three emulsion contents
that bracket the estimated recommended emulsion content.
EE
Add moisture that is expected to be added at the milling head, typically 1.5 to 2.5 percent
If any additives are in the mixture, introduce the additives in a similar manner that they will be
added during field production.
Mixing of test specimens shall be performed with a mechanical bucket mixer. Mix the CIR RAP
millings thoroughly with water first, then mix with emulsion. Mixing shall occur at ambient
temperature. One specimen shall be mixed at a time. Mixing time with emulsion should not
exceed 60 seconds.
• Compaction - Specimens shall be compacted immediately after mixing. Place paper disks on
the top and bottom of the specimen before compaction. Specimens shall be compacted with a
Superpave gyratory compactor (SGC) in a 100 mm mold at 1.250 angle, 600 kPa ram pressure,
and 30 gyrations. The mold shall not be heated.
• Curing after compaction - Extrude specimens from molds immediately after compaction.
Carefully remove paper disks.
Place specimens in 60°C forced draft oven with ventilation on sides and top. Place each
specimen in a small container to account for material loss from the specimens. Care should be
taken not to over -dry the specimens. Cure compacted specimens to constant weight but no more
than 48 hours and no less than 16 hours. Constant weight is defined here as 0.05% change in
weight in 2 hours. After curing, cool specimens at ambient temperature a minimum of 12 hours
and a maximum of 24 hours.
• Measurements - Determine bulk specific gravity (density) of each compacted (cured and
cooled) specimen according to ASTM D2726.
Determine specimen heights according to ASTM D3549 or equivalent. Alternatively, the height
can be obtained from the SGC readout.
Determine Rice (maximum theoretical) specific gravity, ASTM D2041, except as noted in Item 4
of this procedure, and do not break any agglomerates which will not easily reduce with a flexible
spatula. Perform the supplemental dry -back procedure to adjust for uncoated particles.
Determine percent air voids in accordance with ASTM D3203 for each design emulsion content.
Determine corrected Marshall Stability by ASTM D1559 at 40°C after 2 hour temperature
conditioning in a forced draft oven.
• Moisture Susceptibility - Perform same conditioning and volumetric measurements on
moisture -conditioned specimens as on other specimens. Vacuum saturate to 55 to 75 percent,
soak in a 25°C water bath for 23 hours, followed by a one hour soak at 40°C. Determine
corrected Marshall Stability. The average moisture conditioned specimen strength divided by
the average dry specimen strength is referred to as retained stability.
• Emulsion Content Selection - The properties of the specimens at design emulsion content shall
meet the properties in Table 1.
FF
• Report - The report shall contain the following minimum information: Gradation of RAP;
amount and gradation of virgin aggregate or additional RAP, if any; recommended water content
range as a percentage of dry RAP; optimum emulsion content as a percentage of dry RAP and
corresponding density; air void percentage; absorbed water percentage; Marshall Stability and
Retained Stability at design moisture and emulsion contents; Raveling percentage; and Thermal

Maintain all equipment in a satisfactory operating condition and in accordance with the 1010 FDOT
Standard Specifications for Road and Bridge Construction, Section 100-2.
The Cold In -Place Recycling shall be conducted with the equipment specified herein.
Milling Machine:
A 10 foot and a 12 foot mill, self-propelled, bi-directional, down -cutting, lateraUhorizontal mixing, cold
milling machine capable of pulverizing the existing asphalt (and base material as needed) in a single
pass to the depth shown on the plans will be required. The machine shall have automatic depth controls
to maintain the cutting depth to within ± y, in (6 nun) of that shown on the plans and shall have a
positive means for controlling cross slope elevations. A 30 foot non -contact averaging beam must be
used on the mill. The use of a heating device to soften the pavement will not be permitted. Up -cutting
machines shall not be permitted. Machines that only provide vertical mixing will not be permitted.
The milling machine must be equipped with a liquid metering device capable of adjusting the flow of
asphalt emulsion to compensate for any variation in the speed of the machine. The metering device shall
deliver the amount of asphalt emulsion to within ± 0.2 percent of the required design amount by weight
of pulverized bituminous material (for example, if the design requires 3.0 percent, the metering device
shall maintain the emulsion amount between 2.8 percent and 3.2 percent). The asphalt emulsion pump
should be of sufficient capacity to allow emulsion contents up to 3.5% by weight of pulverized
bituminous material. Also, automatic digital readings will be displayed for both the flow rate and total
amount of pulverized bituminous material and asphalt emulsion in appropriate units of weight and time.
Bituminous Paver:
A self-propelled high density paver having tamper bar compaction, electronic grade and cross slope
control for the screed shall be utilized. The equipment shall be of sufficient size and power to spread
and lay the mixture in one smooth continuous pass to the specified section and according to the plans. A
30 foot non -contact averaging beam must be used on the bituminous paver. To reduce material
segregation, the bituminous paver must utilize a hopper insert.
Rollers:
All rollers shall be self-propelled. The number, weight and types of rollers shall be as necessary to
obtain the required compaction. At least one pneumatic -tired roller shall have a minimum gross
operating weight of not less than 50,000 tbs. (22,600 kg). pneumatic rollers must have property working
scrapers and water spraying systems. At least one double drum vibratory steel -wheeled roller shall have
a gross operating weight of not less than 20,000 lbs. (9,000 kg) and a width of 78 inches (1980 mm).
Double drum vibratory rollers must have properly working scrapers and water spraying systems.
Cement Delivery Equipment:
Ensure cement is spread uniformly and accurately during the recycling process with a cement spreader.
The cement spreader shall be equipped with a bag house, curtains and capable of spreading 25 tons at
one time before being reloaded. Cement will not be allowed to be spread with spreader bars from a
tanker. Minimize the amount of airborne cement dust to the satisfaction of the Engineer and in
accordance with OSHA regulations.
Experience:
All contractors and their subcontractors shall be FDOT prequalified in the work classes of drainage,
flexible paving, grading, and hot plant—mixed bitumen courses. Bidders must submit with the bid a
minimum of five CIR project references from a City or County in the State of Florida, that have been
completed within the past three years. Bidders may be required to submit detailed information regarding
the staff that they propose for this project. The contractor shall be capable of meeting all the
requirements of this specification at the time of the bid. The contractor shall have in their possession at
the time of bidding, two (2) or more CIR machines as described in the equipment section of the
specification. Staff shall have the option to inspect the Contractor's equipment and if found deficient, it
shall be the basis for rejection of Contractor's bid.
Construction:
Removal of Vegetation:
Grass, vegetation and other deleterious material shall be removed from the edge of the existing
pavement to prevent contamination of the pulverized bituminous material during the milling operation.
Nmling:
The existing pavement shall be milled to the required depth and width as indicated on the plans.
Recycling shall be in a manner that does not disturb the underlying subbase material in the existing
roadway. The milling operation shall be conducted so that the amount of fines occurring along the
vertical faces of the cut will not prevent bonding of the cold recycled materials. Use a small milling
machine, if necessary, to mill longitudinally to the required depth as indicated on the plans along all
curbs and gutters, radius returns, utilities, inlets, around all manholes and any other structures not
accessible or practical to be milled by the milling/mixing machine utilities. The millings produced by
the small mill will be the same as the large mill and of equal gradation to produce a uniform recycled
pavement layer. Inlets/Catch Basins must be covered during the milling and recycling operation to
II
prevent milled material from entering the catch basin area where it could contaminate and/or block the
storm water system.
Processing:
When a paving fabric is encountered during the CIR operation, the Contractor shall make the necessary
adjustments in equipment or operations so that at least ninety percent (90%) of the shredded fabric in the
recycled material is no more that 5 int (3200 mm2). Additionally, no fabric piece shall have any
dimension exceeding a length of 4 inches (100 mm). These changes may include, but not be limited to,
adjusting the milling rate and adding or removing screens in order to obtain a specification recycled
material. The Contractor shall be required to waste material containing over -sized pieces of paving
fabric as directed by the Engineer.
Spreading:
The material shall be spread using a self-propelled paver meeting the requirements under 2017 FDOT
Standard Specificationsfor Road and Bridge Construction, Section 320-5 Heating of the paver screed
will not be permitted. The recycled material shall be spread in one continuous pass, without segregation
and to the lines and grades established by the Engineer.
Compaction:
Compaction of the recycled mix shall be completed using rollers meeting the requirements of the 2017
FDOT Standard Specifications for Road and Bridge Construction Section 330-10. During initial
construction, rolling patterns and sequences shall be established through the construction of a control
strip produced with the CIR equipment and within the pavement section, to determine the target wet
density, using a nuclear moisture -density gauge in accordance with ASTM D2950, backscatter
measurement mode. In all cases, the longitudinal joint must first be rolled followed by the rolling
pattern established by the test strip. The initial pass for the rolling pattern established by the test strip
should begin on the low side and progress to the high side by overlapping of longitudinal passes parallel
to the pavement centerline. Initial rolling should not begin until the emulsion has started to break.
Rollers shall be operated at speeds appropriate for the type of roller and necessary to obtain the required
degree of compaction and prevent defects in the mat. Rolling shall be continued until no displacement is
occurring or until the pneumatic rolter(s) is (are) walking out of the mixture. Final rolling to eliminate
pneumatic tire marks and to achieve density shall be done by double drum steel roller(s), either
operating in a static or vibratory mode. Vibratory mode should only be operated at a speed, frequency
and amplitude shown not to damage the pavement. The selected rolling pattern shall be followed unless
changes in the recycled mix or placement conditions occur and the established rolling pattern is causing
damage to the mat or the required degree of compaction is unachievable. These circumstances require
the establishment of new rolling patterns and sequences through the construction of a control strip
produced with the CIR equipment and within the pavement section. Rolling shall start no more than 30
minutes behind the paver. Finish rolling shall be completed no more than one hour after milling is
completed. When possible, rolling shall not be started or stopped on uncompacted material but with
rolling patterns established so that they begin or end on previously compacted material or the existing
pavement.
Return of Traffic:
After the completion of compaction of the recycled pavement layer, no traffic shall be permitted on the
completed recycled material for at least one (I) hour. After one hour rolling traffic may be permitted on
the recycled material. This time may be adjusted by the contractor to allow establishment of sufficient
JJ
cure so traffic will not initiate raveling. After opening to traffic, the surface of the recycled pavement
layer shall be maintained in a condition suitable for the safe movement of traffic.
Protection and Damage:
Protect the recycled pavement layer in accordance with the 2017 FDOT Standard Specifications for
Road and Bridge Construction, Section 330-13. After the base coursehas been finished as specified
herein, it shall be protected against drying for a period of 2 to 3 days by the application of a prime coat
as specified in FDOT Standard Specifications section 300 at a rate of not less than 0.15 gal/sy. The
curing method shall begin as soon as possible, but no later than 24 hours after the completion of
finishing operations. The finished base course shall be kept moist continuously until the curing material
is placed. Any damage to the completed Cold In Place Recycled bituminous material shall be repaired
by the contractor prior to the placement of the hot mix asphalt concrete surface course, or other
applicable surface treatment, and as directed by the Engineer.
Finished Recycled Pavement Layer Smoothness:
The completed cold recycled pavement layer surface shall not vary more than '/2 in (12 mm) from the
lower edge of a 10 -foot (3 -meter) straight edge placed on the surface parallel and transversely to the
centerline at locations selected by the City. Irregularities in rideability, cross slope percentages
exceeding 5% or exceeding the specified limit shall be corrected at the expense of the contractor by
grinding/cold milling or leveling with cold or hot mix asphalt. The corrected areas shall be retested to
determine compliance with smoothness.
_Quality Control
Contractor Responsibility:
The contractor shall be responsible for providing field and laboratory quality control testing of materials
during construction. The County or its subconsultant may conduct sampling and testing whenever or as
often as desired for verification purposes. The contractor shall acquire an adequate amount of material
for each sample to be tested in the laboratory so that an ample amount of material is left over in case of
the need for resolution testing. Resolution testing will be required and provided at the expense of the
contractor if similar laboratory samples tested by the contractor and the County do not coincide within
reasonable values as determined by the County. The resolution laboratory will be selected by the County
and the testing results provided by this lab will be used for materials acceptance purposes. All materials
testing laboratories shall be accredited by the AASHTO Materials Reference Laboratory (AMRL) or
Construction Materials Engineering Council (CMEC). The contractor shall submit all documentation of
field inspection and laboratory testing results required herein to the County Engineer prior to payment
and upon request. Copies of all delivery tickets and notes regarding any materials brought to the project
site shall be given to the County upon delivery to the project site. These tickets shall be signed by an
approved representative of the Contractor at the time of delivery.
Crushed RAP Material Sizing:
A sample shall be obtained from the receiving hopper of the paver each 'f: mile or as specified by
engineer (0.8 km) and screened using a 2 in. (51 mm) sieve (or smaller sieve if required) to determine
maximum particle size requirement compliance. The resulting gradations shall be compared to the mix
design gradations to determine any necessary changes to emulsion content. Gradation results shall be
shared with the County by the end of the following day. Sampling procedures shall be in accordance
with ASTM D979 or AASHTO T168.
Asphalt Emulsion:
The asphalt emulsion shall be received on the job site within the temperature ranges specified by the
emulsion supplier. The emulsion supplier shall provide testing results for each shipment indicating the
emulsion is in compliance with the criteria specified in Table 4. The County Engineer may require the

FOG SEAL SPECIFICATIONS
The work specified in this section consists of furnishing and applying fog seal on existing roads at application
rates described here -in.
Description: Fog seals are a method of adding asphalt to an existing pavement surface to improve sealing or
waterproofing, prevent further stone loss by holding aggregate in place, or simply improve the surface
appearance. Generally, fog seal is a light spray application of diluted asphalt emulsion used primarily to seal an
existing asphalt surface to reduce raveling and enrich dry and weathered surfaces. However, inappropriate use
can result in slick pavements and tracking of excess material.
Materials:
The emulsion types recommended for fog seals may be cationic (i.e., a positive surface charge on the asphalt
particles), or anionic (i.e., a negative surface charge on the asphalt particles). The primary types used are CSS -
1 h and SS -1 h. In some circumstances, CQS-1h (and LMCQS-1 h) will give a faster set.
Liquid emulsified bituminous material for dilution: CSS -1h liquid bituminous material conforming to the
requirements of AASHTO M 208 or SS -1 h conforming to the requirements of AASHTO M 140 (except as modified
herein) shall be utilized. The contractor shall certify the liquid bituminous material meets the aforementioned
specifications
The asphalt emulsion may contain up to 43% water prior to dilution. Original emulsion water and dilution water
shall be limited to and not exceed for any reason 50% by volume. Therefore, residual asphalt shall equal 50%
(+l%, -O%).
Dilution Water and Emulsion Water: Water introduced into the asphalt must be potable and free from
detectable solids or incompatible soluble salts (hard water).
Material Samples:
The County will require the Contractor to sample and test each load of emulsion prior to delivery. The Contractor
will also provide a sample of the emulsion, on site, prior to commencing work. The County will require the
Contractor to provide sample containers and a local Independent testing laboratory for the analyzing of emulsion.
The Contractor will be responsible for the cost of the testing. The County reserves the right to test any shipment
of emulsion that is believed to be of substandard. All samples shall be shipped and stored in clean air tight sealed
wide mouth jars or bottles made of plastic.
Equipment:
Distributor:
The liquid bituminous material shall be applied with a truck mounted, pressure distributor that has been calibrated
within the previous twelve (12) months, for transverse and longitudinal application rate. The distributor shall be
equipped, maintained and operated so that the bituminous material can be applied at controlled temperatures and
rates from .03 to .22 gallons per square yard with nozzles adjusted to allow minimum overlap of 3x. The distributor
shall be capable of applying bituminous material of variable widths up to twenty-four (24) feet. The distributor shall
uniformly apply the bituminous material to the specified rate with a maximum allowed variation of 0.015 gallons per
square yard. Distributor equipment shall include tachometer, accurate volume measuring device, a calibrated tank
and a thermometer for measuring the temperature of the tank's contents. Distributors shall be equipped with an
asphalt pump and full circulating spray bars adjustable laterally and vertically. Distributors and transport trailers
shall be equipped with a sampling valve. Distributor trucks shall be of the pressure type with insulated tanks. The
use of gravity distributors will not be permitted. The valves shall be operated by levers so that one or all valves may
be quickly opened or closed in one operation. The valves which control the flow from nozzles shall act positively so
as to provide a uniform unbroken spread of bituminous material on the surface. The distributor shall be equipped
with devices and charts to provide for accurate and rapid determination and control of the amount of bituminous
material being applied and with a bitumeter of the auxiliary wheel type registering speed in feet per minute, and trip
and total distance in feel.

335-3 Material Performance:
The asphalt rejuvenating agent shall have the capability to penetrate the asphalt pavement surface.
The asphalt rejuvenating agent shall be absorbed and incorporated into the asphalt binder. Verification that
said incorporation of the asphalt rejuvenating agent into the asphalt binder has been effected shall be by
analysis of the chemical properties the asphalt binder.
The viscosity shall be reduced by a minimum of 25% for a pavement two years or less in age, and
reduced by a minimum of 40% for a pavement greater than two years in age as determined by dynamic shear
rheometer (DSR) method for asphalt testing in accord with AASHTO T315-05. This analysis shall apply to
extracted asphalt binder, taken from cores extracted fifteen to thirty days following application, in the upper
3/8 inch of pavement. In addition, the treated areas shall be sealed in-depth to the intrusion of air and water.
The Engineer will require that untreated and treated core samples, a minimum of six inches in
diameter, be removed by the Contractor at locations indicated by the Engineer. The treated core sample shall
be taken in the same lane in close proximity to each untreated sample. A minimum of one untreated and
treated core sample shall be taken for each pavement group or one per 50,000 square yards of treated
pavement in each pavement group.
335-4 Equipment:
335-4.1Distributor: The distributor for spreading the emulsion shall be self-propelled, and shall have
pneumatic tires. The distributor shall be designed and equipped to distribute the asphalt rejuvenating agent
uniformly on variable widths of surface at readily determined and controlled rates from 0.04 to 0.5 gallons
per square yard of surface, and with an allowable variation from any specified rate not to exceed 5% of the
specified rate.
Distributor equipment shall include full circulation spray bars, pump tachometer, volume measuring
device and a hand hose attachment suitable for application of the emulsion manually to cover areas
inaccessible to the distributor. The distributor shall be equipped to circulate and agitate the emulsion within
the tank.
The rate of application shall be controlled by an onboard computer control system designed to
uniformly and consistently control the selected application rate in gallons per square yard regardless of the
forward speed of the distributor truck.
A check of distributor equipment as well as application rate accuracy and uniformity of distribution
shall be made when directed by the Engineer.
3354.2 Sand Truck: The tmck used for sanding shall be equipped with a spreader that allows the sand to be
uniformly distributed onto the pavement. The spreader shall be able to apply 1/2 pound to 3 pounds of sand
per square yard in a single pass. The spreader shall be adjustable so as not to broadcast sand onto driveways
or to lawns.
The sand to be used shall be manufactured sand free flowing, without any leaves, dirt, stones, etc.
Any wet sand shall be rejected from the job site.
Any equipment that is not maintained in full working order, or is proven inadequate to obtain the
results prescribed, shall be repaired or replaced at the direction of the Engineer.
3354.3 Calibration:
Distributor -Prior to construction, calibrate the distributor in accordance with ASTM D2995-99 in the
presence of the Engineer. The distributor shall be moving forward at the proper application speed at the time
the spray bar is opened. If at any time a nozzle becomes clogged or not spraying a proper pattern, the
operation shall be immediately halted until repairs are made.
Sand Spreader- Prior to construction, calibrate the spreader in accordance with ASTM D5624-02, in the
presence of the Engineer. The allowable deviation in the amount of manufactured sand spread on each of the
TT
rubber mats shall not exceed plus or minus I pound per square yard in the transverse direction, or plus or
minus 1 pound per square yard in the longitudinal direction, from the design application rate.
UU
335-5 Construction:
335-5.1 Layout: The Contractor will be responsible for the lay out of the roadway and project planning and
sequencing to meet traffic control requirements prior to paving.
335-5.2 Weather and Seasonal limitations: The asphalt -rejuvenating agent shall not be applied to a wet
surface or when rain is occurring or the threat of rain is present immediately before placement. The surface
treatment shall not be applied when the temperature is less than 400 in the shade. When applying emulsions,
the temperature of the surface shall be a minimum of 59°F, and no more than 140°F.
If unexpected rain occurs prior to material penetration and sanding, the agent shall be reapplied at no cost to
the county. Further, the contractor's traffic control and project monitoring shall continue until the application
has penetrated, area has been sanded and the resultant surface is not slippery or dangerous to vehicular travel.
335-5.3 Preparation of Surface: The contractor will be responsible for blowing or sweeping the road
immediately ahead of the application operation to make sure the road is free of standing water, dirt, loose
aggregate and other debris. The surface shall be clean and dry prior to the application.
335-5.4 Application of asphalt rejuvenating emulsion: The asphalt -rejuvenating agent shall be applied by
a distributor truck at the temperature recommended by the manufacturer and at the pressure required for the
proper distribution. The emulsion shall be so applied that uniform distribution is obtained at all points of the
areas to be treated. Distribution shall be commenced with a running start to insure full rate of spread over the
entire area to be treated. Areas inadvertently missed shall receive additional treatment as may be required by
hand sprayer application.
335-5.4.1 Material Placement: Application of asphalt rejuvenating agent shall be on one-half width of the
pavement at a time. When the second half of the surface is treated, the distributor nozzle nearest the center of
the road shall overlap the previous application by at least one-half the width of the nozzle spray. In any event
the centerline construction joint of the pavement shall be treated in both application passes of the distributor
truck.
Before spreading, the asphalt rejuvenating agent shall be blended with water at the rate of two parts
rejuvenating agent to one part water, by volume or as specified by the manufacturer. The combined mixture
of asphalt rejuvenating agent and water shall be spread at the rate of 0.04 to 0.10 gallons per square yard, or
as approved by the Engineer following field testing.
Where more than one application is to be made, succeeding applications shall be made as soon as
penetration of the preceding application has been completed and the Engineer grants approval for additional
applications. Grades or super elevations of surfaces that may cause excessive runoff, in the opinion of the
Engineer, shall have the required amounts applied in two or more applications as directed. After the street
has been treated, the area within one foot of the curb line on both sides of the road, when directed shall
receive an additional uniformly applied treatment of the asphalt rejuvenating emulsion as directed by the
engineer.
The Contractor shall furnish a quality inspection report showing the source, manufacturer, and the
date shipped, for each load of asphalt rejuvenating agent. When directed by the Engineer, the Contractor
shall take representative samples of material for testing.
335-5.4.2 Test Strip for Application Rate: Prior to start of the project, the contractor shall perform test strip
applications as directed by the engineer. Test strips shall be performed for each pavement group of similar
age and type within the project area.
The test strips shall be applied at a minimum width of 6 feet and for a length of 50 feet. A total of
three test strips shall be applied at application rates of 0.04, 0.08 and 0.10 gallons per square yard,
W
respectively. The time, in minutes, for essentially complete absorption of the asphalt rejuvenating emulsion
shall be recorded for each test strip. The optimal rate to be used in a given area shall be that rate essentially
absorbed within 30 minutes.
In the event that all three of the standard test rates are absorbed completely within the 30 minute
timeframe, then the Contractor and the Engineer shall agree on a fourth test strip application rate.
Upon completion of the test strips for each pavement group, the Engineer will determine the final application
rate to be applied to each pavement group.
335-5.4.3 Sanding/Blotting: After the rejuvenating emulsion has penetrated, and when recommended by the
Contractor and approved by the Engineer, a coating of dry manufacture sand shall be applied to the surface
in sufficient amount to protect the traveling public as required.
All manufactured sand used during the treatment must be removed no later than 24 hours after treatment of a
roadway. This shall be accomplished by a combination of hand and mechanical sweeping. All turnouts, cul-
de-sacs, etc. must be cleaned of any material to the satisfaction of the Engineer. Street sweeping will be
included in the price bid per square yard for asphalt rejuvenating emulsion.
If, after manufactured sand is swept and in the opinion of the Engineer a hazardous condition exists
on the roadway, the contractor must apply additional manufactured sand and sweep same no later than 24
hours following reapplication. No additional compensation will be allowed for reapplication and removal of
materials.
335-5.4.4 Handling of Asphalt Rejuvenating Agent: Contents in tank cars or storage tanks shall be
circulated at least 45 minutes before withdrawing any material for application. When loading the distributor,
the asphalt rejuvenating agent concentrate shall be loaded first and then the required amount of water shall be
added. The water shall be added into the distributor with enough force to cause agitation and thorough
mixing of the two materials. To prevent foaming, the discharge end of the water hose or pipe shall be kept
below the surface of the material in the distributor that shall be used as a spreader. The distributor truck will
be cleaned of all of its asphalt materials, and washed out to the extent that no discoloration of the emulsion
may be perceptible. Cleanliness of the spreading equipment shall be subject to the approval and satisfaction
of the Engineer.
335-5.4.5 Street Sweeping: The Contractor shall be responsible for sweeping and cleaning of the streets
after treatment. All sand used during the treatment most be removed no later than 48 hours after treatment of
the street. This shall be accomplished by a combination of hand and mechanical sweeping. All turnouts, cul-
de-sacs, etc. must be cleaned of any material to the satisfaction of the Engineer.
If, after sand is swept and in the opinion of the Engineer a hazardous condition exists on the roadway, the
contractor most apply additional sand and sweep same no later than 24 hours following reapplication. No
additional compensation will be allowed for reapplication and removal of sand.
335-5.4.6 Resident Notification: The contractor shall distribute by hand, a typed notice to all residences and
businesses on the street to be treated. The notice will be delivered no more than 24 hours prior to the
treatment of the road. The notice will have a local phone number that residents may call to ask questions.
The notice shall be of the door hanger type, which secures to the door handle of each dwelling. Unsecured
notices will not be allowed. The contractor shall also place the notice on the windshield of any parked cars
on the street. Hand distribution of this notice will be considered incidental to the contract.
335-5.6 Traffic Control.
The Contractor shall famish all necessary traffic control, barricades, signs and flagmen, to ensure the safety
of the traveling public and to all working personnel. Traffic shall not travel on fresh Asphalt Rejuvenator
until penetration, in the opinion of the Engineer, has become complete and the area is suitable for traffic. The
Contractor shall submit an M.O.T plan indicating all facets of traffic control for the project area. The MOT
WW
plan must be approved in writing by the Engineer prior to commencing any work. All traffic control shall be
in accordance with the FDOT Roadway Design Standards, most current edition and TP -102. M.O.T. and
associated devices shall be checked daily and periodically throughout the project for compliance; and where
adjustments or corrections are needed, prompt revisions shall be made.
335-5.7 Method of Measurement.

employees for violations of such prohibition.

drug-free workplace, any available drug counseling, rehabilitation, and employee assistance programs, and the
penalties that may be imposed upon employees for drug abuse violations.
3. Give each employee engaged in providing the commodities or contractual services that are under Bid a copy of
the statement specified in subsection (1).
4. In the statement specified in subsection (1), notify the employees that, as a condition of working on the

will notify the employer of any conviction of, or plea of guilty or nolo contendere to, any violation of chapter 893
or of any controlled substance law of the United States or any state, for a violation occurring in the workplace no
later than five (5) days after such conviction.
5. Impose a sanction on, or require the satisfactory participation in a drug abuse assistance or rehabilitation
program if such is available in the employee's community, by any employee who is so convicted.
6. Make a good faith effort to continue to maintain a drug-free workplace through implementation of this section
As the person authorized to sign the statement, I certify that this firm complies fully with the above requirements.
