2022 PAVEMENT MANAGEMENT FINAL PROJECT REPORT
EXECUTIVE SUMMARY
The City of Sebastian contracted with Pavement Management Group (PMG) to provide a turn -key
Pavement Management Program (PMP). The backbone of PMG's turnkey PMP is the PAVER Pavement
Management System (PMS) which provides specific tools such as pavement modeling, maintenance
decision trees and budget/target driven scenarios maximizing the return on investment from available
maintenance and rehabilitation funds, generating a prioritized plan, and identifying specific areas in
need of maintenance and rehabilitation.
• Verify and setup any new pavement network inventory
• Provide an HD video of each pavement section
• Determine total samples to inspect per section
• Identify all distress types, severity levels and quantities within through ASTM D6433-20
• Calculate the Pavement Condition Index (PCI) for each pavement section
• Assign all pavement management data to GIS
• Create GIS current condition map
• Provide an HTML based condition map with geo located streaming HD video
• Provide a complete inventory and condition listing of each pavement section
• Provide a final report of findings
• Provide continued support services
2022 ROADWAY NETWORK SUMMARY
• 151 centerline miles
• 248 lane miles (lane = 12 feet wide)
• 15,704,016 square feet
• 1,412 management sections
• Average network PCI is 72
• Average network condition category of GOOD
INTRODUCTION
PMG was contracted by The City of Sebastian to provide pavement management services for their 151-
centerline mile (248 lane mile) roadway network. Through these services a field inventory setup of any
new roads, an inventory review and inspections were performed on all 1,412 management sections
within the network. All inventory items were added or updated within their PMS database and a PCI was
calculated for each section. HD videos were taken at each section location (from beginning to end of
section). This provides for a virtual, high -definition account of the roadway network, and provides value
in a variety of ways such as condition review and network level decision making from the office. This
report provides a thorough definition of the inspection process performed as well as the condition
results of our project.

CONDITION ASSESSMENT PROCESS
PMG adheres to the ASTM D6433-20 standard for assessing the condition of asphalt and concrete
surfaces. Our skilled inspection team reviews high -definition video of each pavement section in
conjunction with our proprietary artificial intelligence (Al) model to identify and document the distress
types, severity levels, and quantities that are occurring. The data goes into the PAVERTM Pavement
Management System (PMS) for Pavement Condition Index (PCI) calculation, resulting in a PCI score for
each management section within the network(s).
PAVEMENT DISTRESS DEFINITION
20 possible distress types can occur within asphalt -based surfaces and 19 possible distress types that
can occur within a concrete surface. The U.S. Army Corps of Engineers publishes the Asphalt Distress
Manual and the Concrete Distress Manual. These manuals describe each distress type, the criteria to
determine each severity level (low, medium, high), and how to measure each. The asphalt and concrete
distress types are highlighted below in Figure 1.

2022 PAVEMENT MANAGEMENT FINAL PROJECT REPORT
CONCLUSION
The PCI study provides for a PCI rating on each pavement section within the maintained roadway
network. Based upon the distresses identified within each representative sample location inspected, a
PCI number is assigned to each pavement section. This number is on a scale of 0 —100 with 0 being the
worst and 100 being the best.
The City of Sebastian roadway network is approximately 248 lane miles (151 centerline miles) in size.
Through the ASTM D6433-20 PCI study, PMG has determined the roadway network has an average PCI
of 72 and is classified as being in GOOD condition.
PMG would again like to thank you for the opportunity to provide Sebastian with this PCI study and our
pavement management services. Our goal is to provide the highest level of services and support,
providing our clients with the data, tools, and expertise necessary to be successful in their goals of
pavement management. Should you require any additional information or support regarding this PCI
study or the PAVERTM PMS, please do not hesitate to ask.

CITY COUNCIL AGENDA TRANSMITTAL
Council MeetinL Date: July 12, 2023
Agenda Item Title: City Council Approval of the Final Project Report Prepared by Pavement
Management Group Inc. (PMG).
Recommendation: Staff Recommends Approval of the Final Project Report Prepared by
Pavement Management Group, Inc.
Background: In January of 2022 Council approved a "piggybacking" contract with
Pavement Management Group (PMG) for pavement management services. The contract required an
assessment of our City roads to determine the average pavement index rating. This is routinely assessed on a
three to five year basis, and was last completed in 2018/2019. Between January and November 2022 PMG
drove all City owned roads documenting their condition.
In this report they have documented the condition of each individual City road as well as compiled the
information to determine the City has an average 72 point rating on the Pavement Condition Index, or PCI
score. Therefore, on average, our City roads fall within the "Good" condition category. The analysis in
2018/2019 found an average score of 75, showing our PCI has only decreased 3 points. This shows that our
efforts of reconstruction and repaving as well as pavement preservation have been working to greatly reduce
the rate at which our PCI index has changed.
We are requesting Council formally approve this Pavement Management Group, Inc. Final Project Report.
With this approval staff will move forward with finalization of the City's paving and preservation plan
through fiscal year 2028.
