Abstract:

This study evaluated the effect of a given thickness of asphaltic concrete overlay in rehabilitating 53 test sections conforming to the experiment design. This factorial design specified various levels of traffic intensity and overlay thickness for both rigid and flexible pavements. Secondary variables considered were existing pavement structure components and quality of each, subgrade soil conditions, environment, and quality of the overlay mix.

This report presents analyses based on 11 semiannual evaluations of the test sections. Evaluation was comprised mainly of deflection and serviceability measurements and visual inspections.

Asphaltic concrete overlay thickness design guides have been developed for flexible, composite, and rigid pavements. Traffic load accumulations, deflection reduction properties of the overlays, and deflection measurements at failure provided the bases for analyses.
