A Pavement Management System for Concrete Roadways in Virginia: Phase I: Condition Ratings: Final Report

Report No: 88-R21

Published in 1988

About the report:

This report traces the development of a rating system proposed by the author and reviewed by a subcommittee of the Pavement Management Research Advisory Committee for use in evaluating the service condition of Virginia's Portland cement concrete pavements. The service condition is assessed in terms of distress roughness, i.e., that portion of a pavement's poor ride characteristics directly attributable to the occurrence of certain key distress types. The key distresses identified for jointed concrete pavements are permanent patching, lane/shoulder separation, transverse joint faulting, transverse joint seal damage, and scaling, map cracking, or crazing. For continuously reinforced pavements, spacing of transverse cracks, lane/shoulder separation, and scaling, map cracking, or crazing were identified. Field surveys of the occurrence of these distresses provided the necessary data for estimating distress roughness through the use of prediction equations that have been established from the standard statistical analysis of pavement section distress data and roughness measurements. The use of distress roughness to reflect a pavement's service condition provides a common basis for comparison of pavement sections. This, in turn, enables managers to set priorities for pavement rehabilitation. These rating procedures and a comprehensive system for managing Portland cement concrete pavements will be implemented in a subsequent project.
