Influence of Ultraviolet Irradiation Quantity on Asphalt Rheological Performance

Abstract:

The DSR was conducted to evaluate the influence of ultraviolet aging on asphalt rheological performance. In the experiment, RTFOT test was used to simulate the short-term aging of asphalt binder, indoor intelligent ultraviolet aging box is used to simulate ultraviolet aging of asphalt. The aging temperature was set at 50 ��C. Aging days were 2 days, 4 days, and 6 days. For high temperature frequency scanning and low temperature frequency scanning of ultraviolet aging asphalt. The experimental results show that the ultraviolet aging have great influence on asphalt basic performance indicators and rheological properties.
