dc.description.abstract Paper presented at the 23rd Annual Southern African Transport Conference 12 - 15 July 2004 "Getting recognition for the importance of transport", CSIR International Convention Centre, Pretoria, South Africa. The aging of asphalt binder is an important factor to asphalt pavement service property. In this paper, rolling thin film oven (RTFO) is used to simulate the short-term age of asphalt binder during construction, then pressure aging vessel (PAV) is used to age the RTFO test residues for different hours. The authors studied the effects of aging on viscoelastic performance of asphalt binder by using bending beam rheometer and dynamic shear rheometer. The results indicate that the aging of asphalt binder will decline its viscous performance and enhance its elastic performance, so its resistance to deformation will be enhanced while its anti-fatigue cracking capacity will decrease. en
