摘要：

In order to meet the requirement of high temperature stability and low temperature crack resistance of asphalt pavement in seasonal frozen soil region of Jilin Province, in this research the diatomite and basalt fiber are simultaneously added into asphalt mixture. Then through the analyses of high temperature stability, low temperature stability, water stability and fatigue properties of compound modified asphalt mixture, the pavement performance of diatomite-basalt fiber composite modified asphalt mixture is evaluated. The results show that the diatomite-basalt fiber composite modified asphalt mixture has good road performance, can significantly improve the high temperature stability of the asphalt mixture, and effectively improve the low temperature crack resistance of the asphalt mixture. The fatigue life of asphalt mixture is greatly improved and the water stability is improved to some extent. © 2020, Jilin University Press. All right reserved.
