The Impact Study of the Resistance to Ultraviolet Radiation Aging Agent on the Airport Road Surface Performance with the Modified Asphalt

Abstract:

According to the test results of before and after the aging of asphalt performance,we analyse the dosage changes of the HALS anti ultraviolet ageing agent to improve SBS modified asphalt ultraviolet light resistance aging performance role. The test results show that GW-944 can better improve the ultraviolet resistance of asphalt aging performance, i.e., original sample asphalt have no other negative influence in a certain extent, and at the same time,also improve asphalt fatigue performance, low temperature performance and high temperature performance after the light aging, but the performance improvement needs to be in the right dosage range;Therefore,to the SBS modified asphalt we can use such ultraviolet aging agent for performance improvement,the research achievement for the airport asphalt pavement UV aging provide a technical basis for effective prevention and treatment.
