Condition Rating – What shape is it in?
Ordered State Ratings
Set of criteria which describe a set of discrete, ordered states.
Professional observer judges state and assigns rating.
Usually most cost effective system
Most subject to variability by rater
• PASER – Pavement Surface Evaluation and Rating
• Maintenance State ―Good – Fair – Poor‖
• MDOT Sufficiency Rating System

Condition Rating – Types of Systems
Index System
Set of criteria which relates physical measurements of distress extent and observer opinion of severity to a numeric rating.
Criteria numerically relate distresses to each other.
Usually requires sampling and reliance on statistics to apply over large network
Index levels may not be discrete
Record of distress propagation
• PCI – Pavement Condition Index (Micropaver)
• MDOT Distress Index

How Do You Pick A Rating System?
• Things to consider
• Sustainable
• Cost to collect
• Use your own staff
• Explainable
• Your boss
• Public
• Other’s in your organization
• Elected officials
• Be descriptive about the asset
• Aid in decision making
![Page 23: Michigan Transportation Asset Management Training...Michigan’s Local Technical Michigan Transportation Asset Management Council Assistance Program Cost Effectiveness of Treatments](https://reader034.fdocuments.net/reader034/viewer/2022051805/5ff999926898bf32853eb92b/html5/thumbnails/23.jpg)

TAMC Pavement Condition Survey
• PASER – Pavement Surface Evaluation and Rating
• Visual survey—based on sound engineering principles
• Measure of surface distress
• Reported on a scale of 1-10
• Council combines into three categories
• Routine maintenance (8 - 10)
• Capital preventive maintenance (5 - 7)
• Structural improvement (1 - 4)
