Pavement Condition Rating System: Development and Implementation of a System for Evaluation of Maintenance Repair Needs and Priorities

摘要

This report volume presents the system for rating visible pavement distress. The system is called Pavement Condition Rating (PCR) and is based upon both severity and extent of distress. Standard definitions and photographs are presented to aid in the identification of distress type, severity and extent. A mathematical expression which deducts points for each occurring distress type permits calculation of the PCR index. PCR for a pavement with no visible distress is 100. This report is intended for use as a field manual to conduct pavement condition rating including tabular forms for rating jointed concrete, continuously reinforced concrete, flexible, and composite pavements.
