    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

  • Michigan Transportation Asset Management Council Michigan’s Local Technical Assistance Program

    17

    Ordered State Rating Block Cracking

    Moderate Progression

    Rutting Less Than ½ Inch

    Transverse Cracks 20 Spacing

    Longitudinal Joint Cracks Present

    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

    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)
