Abstract

This paper aims to study the structural weakening mechanisms of bituminous pavement layers and the effect of traffic loading and binder ageing on the structural deterioration of the pavement. The results of a detailed investigation of in-service motorway pavements are presented. In the investigation, four pavement sites of various age and traffic conditions were examined. Cores were taken from the nearside and offside lanes, and samples were cut from the roadbase of the cores and tested in the laboratory under fatigue loading. The widely held concept of roadbase fatigue cracking was closely examined.
