Abstract:
On the basis of the physical and mechanical properties test of raw materials, the mixing ratio of asphalt mixture AC-13 I was obtained by using the graphical method and adjusting and optimizing the mixing ratio. Through the Marshall test of asphalt mixture under different fiber types and different fiber content, the optimal asphalt dosage OAC of fiber asphalt mixture is obtained, and then the influence of fiber type and content on the dynamic stability of asphalt mixture is studied through high temperature rutting test, and the optimal amount of different types of fiber is obtained. The results show that the fiber can significantly improve the high temperature performance of asphalt mixture. Different kinds of fibers correspond to different optimal amounts in asphalt mixtures. Finally, a calculation model of the dynamic stability of the matrix asphalt mixture is established, considering the dynamic stability of the matrix asphalt mixture, the influence of fiber content and fiber type.
