Influence of Polyester Fiber on Road Performance of Different Types of Asphalt Mixture
In order to explore the solution to the early disease of asphalt pavement and improve the long-term pavement performance of asphalt mixture,the performance difference of AC-13 and SMA-13 asphalt mixture before and after adding polyester fiber was analyzed in this paper,and the anti-skid performance,water stability,low temperature crack resistance and high temperature stability of asphalt mixture were tested.The results show that the pavement performance of SMA-13 and AC-13 asphalt mixtures can be effectively improved by adding polyester fiber,and the high temperature stability of AC-13 and the low temperature crack resistance of SMA-13 and polyester fiber can be improved signifi-cantly.The improvement of water stability of the two asphalt mixtures after adding polyester fiber is roughly the same,but the surface structure depth is reduced,resulting in a decrease in skid resistance.
