Paper Title:
Effects of UV Aging on the High-Temperature and Fatigue Performances of Asphalt Mortar
  Abstract

Ultraviolet(UV) radiation is one of the main factors induce asphalt aged in the field in-service. Asphalt mortar greatly affects the pavement performance. It is scarce that studies concerning UV aging on the performance of asphalt mortar. In this paper, asphalt mortar with a 1.0 F/A (filler to asphalt)after UV aging were subjected to the test of the Dynamic Shear Rheometer (DSR).Effects of UV aging on the High-Temperature and fatigue performances of asphalt mortar were studied by using the rutting parameter G*/sinδ, fatigue parameter G*sinδ and dynamic viscosity. The results show UV aging had prominent effect on asphalt mortar’s properties, with the decrease of film thickness and increase of UV aging temperature, the ability of rut resistance enhances and fatigue performance weakens.
