Design of Overlays Based on Pavement Condition, Roughness, and Deflections

Report No: 82-R31

Published in 1982

About the report:

Changing economic conditions have led to a need for more objective means of prioritizing pavement resurfacing needs and for determining the required thickness of resurfacings. Both of these issues have been addressed in the study for which this document constitutes the final report. Earlier reports on the study were directed at the development of a pavement maintenance rating system and a tentative method for designing the thickness of overlays. The present report is divided into two parts. The first deals with field trials and verification of the pavement rating system and the second with further development of thickness design procedures. Among the major findings of the study are : 1. An objective rating system can be used to provide a common basis of comparison of pavements between various raters. 2. Methods for designing the thickness of overlays based on the volume of traffic and the existing pavement structure, or on a combination of the two, appear to be practical. Material developed in the study is being used in an inventory of Virginia interstate pavements.
