Influence of Modifier Dosage and Aging Time on the SBS Modified Asphalt

Wang, Bai Lin / Zheng, Min Nan / Zhang, Jie / Geng, Jiu Guang

SBS modified asphalt has good performance of high temperature and low temperature, it is widely used in high-grade asphalt pavement engineering. But the aging will influence the using performance of asphalt, we select four dosages of modifier and aging for different time, Experimental results show that with the increase of aging time, asphalt penetration is reduced, softening point is elevated, ductility is decreased. According to the macro physical index analysis, find that SBS modified asphalt’s anti-aging performance is improved.
