This document discusses best practices for sustainable pavement management. It recommends having a complete inventory of pavement segments, collecting consistent condition data regularly, developing accurate prediction models, selecting appropriate treatments, analyzing budget and condition scenarios, and choosing an integrated pavement management tool that supports the agency's needs. The goal is to objectively prioritize projects, optimize limited funds, and increase pavement network credibility through an informed decision-making process.

Outline
• Introduction to Pavement Management
• Best Practices for
• Inventory
• Segmentation
• Condition assessment data
• Condition prediction models
• Treatment and activity planning
• Budget & condition scenario
• Selecting a pavement management tool
• Summary

3. BEST PRACTICES IN SUSTAINABLE PAVEMENT MANAGEMENT
What is Pavement Management?
• APWA defines it as “…a systematic method for routinely
collecting, storing, and retrieving decision-making
information needed to make maximum use of the limited
maintenance dollars.”
• The process of maintaining pavements effectively and
efficiently
• A series of steps that collectively help agencies analyze maintenance
alternatives

4. BEST PRACTICES IN SUSTAINABLE PAVEMENT MANAGEMENT
Benefits of Pavement Management
• To support informed decision making at various levels
• Strategic—Policy makers can use it for long-term strategic
planning (e.g. State Legislature)
• Network—Local agencies use it for short- and long-term
budgeting (e.g. City Council)
• Project—Local agencies use it for project selection and planning
(e.g. Public Works & Engineering Departments)

5. BEST PRACTICES IN SUSTAINABLE PAVEMENT MANAGEMENT
Why Use Pavement Management?
• Objective selection of projects
• Identify the right treatment for the right segment at the right
time
• Optimize the use of available funds; justification for more
funds
• Increased credibility

SUSTAINABLE PAVEMENT MANAGEMENT

7. BEST PRACTICES IN SUSTAINABLE PAVEMENT MANAGEMENT
Inventory
• The minimum inventory needed
• Roadway name, pavement type, description of location, and construction
history
• Inventory—best practices
• Functional classification, layer types & thickness, subgrade information,
traffic information, number of lanes

8. BEST PRACTICES IN SUSTAINABLE PAVEMENT MANAGEMENT
Segmentation
• Two general methods of segmentation
• Dynamic Segmentation changes based on pavement characteristics (traffic,
construction, condition)
• Static Segmentation is predefined (block-to-block, fixed lengths)
• Static is better for integrated systems; dynamic is better for stand-
alone systems
• Segmentation/network map should be GIS-based
• Segmentation dimensions should be included in the inventory

9. BEST PRACTICES IN SUSTAINABLE PAVEMENT MANAGEMENT
Condition Data
• Two general methods of collection
• Automated uses vehicles equipped with cameras and sensors
• Manual relies on boots on the ground; relatively less-preferred
• Semi-automated methods combine camera and sensor data with manual
interpretation
• Identify methodology used to calculate condition index
• ASTM (measured), PASER (estimated), other
• Collect frequent and consistent data; 3 year cycles are recommended

10. BEST PRACTICES IN SUSTAINABLE PAVEMENT MANAGEMENT
Condition Prediction Models
• Prediction models need to be accurate and practical
• Create models based on available data
• Create models to account for all variability
• Models based on functional classification (arterial, collectors, etc.)
• Models based on pavement type (AC, PCC, Overlay, Surface Treatment, etc.)
• Review and update models regularly (annually preferred)

11. BEST PRACTICES IN SUSTAINABLE PAVEMENT MANAGEMENT
Treatment & Activity Planning
• Decision matrix needs to be developed
reflecting agency practice
• Include updated unit cost
• Decision matrix & treatment types
should be reviewed annually
• Incorporate pavement preservation

12. BEST PRACTICES IN SUSTAINABLE PAVEMENT MANAGEMENT
Budget & Condition Scenarios
• Optimizes project selection and prioritization based on strategy
• Facilitates timely pavement preservation applications
• Typical Budget/Condition Scenarios to run
• Budget—current budget, unlimited funding, no funding,
• Condition—maintain current condition, reach target condition
• Typical periods are 5 years. Do not exceed 10 year periods
• Update plan annually

Selecting a Pavement Management Tool
Dos and Don’ts
• Create a detailed list of features you need
• Do not compromise features and usability
• Talk with more than one vendor
• Get recommendations from other users
• Take all the time you need

14. BEST PRACTICES IN SUSTAINABLE PAVEMENT MANAGEMENT
Selecting a Pavement Management Tool
What to look for
• Has a map interface/integrates with GIS
• Is easily accessible (web-based, mobile ready)
• Supports pavements specifically (not a custom build)
• Flexible and configurable
• Allows for scenario analysis
• Easy to import and export data

15. BEST PRACTICES IN SUSTAINABLE PAVEMENT MANAGEMENT
Summary
• Have a complete inventory
• Choose the segmentation that works for you
• Collect consistent and frequent data
• Update your models regularly
• Choose triggers and treatments that work for roads
• Forecast future budget needs
• Select the right PM tool
