STATEWIDE FLEXIBLE PAVEMENT PERFORMANCE AND DEFLECTION STUDY

J Skog, J A Matthews, G W Mann, Debra Roberts

Abstract

Pavement deflection measurements are utilized to evaluate residual in-place strength of flexible pavement sections. Asphalt concrete structural overlay thickness requirements for 10-year service life extensions are determined based on reduction of initial deflections to tolerable deflection levels for given conditions. Asphalt properties were studied to determine effects upon pavement performance and deflections of flexible pavements. Experimental materials and methods are studied under various climatic and traffic conditions in efforts to minimize or control pavement reflection cracking through AC overlays. /FHWA/
