The Ageing Characteristics of Base Asphalt under UV in the Construction of the Airport

Article Preview

Abstract:

In order to research how the strong ultraviolet impact on the performance of base asphalt, it utilizes the chambers of ultraviolet ageing environmental to simulate the field ageing conditions. The high temperature properties of base asphalt under different time of ultraviolet irradiation is researched by the SHRP equipment. The results show that the influence of high temperature performance is relatively small when the base asphalt under the strong ultraviolet rays, and it has a closer relationship with the ageing time. The value of G*/sinδ that is anti-rutting factor increase 87.2% at most.
