Effect of basalt fiber with different diameter on asphalt mixture performance
In order to study the influence of basalt fiber diameter parameters on the performance of AC-13C asphalt mixture,the high temperature performance,low temperature performance and cracking performance of asphalt mixture modified with three different diameter fibers of 7,13,25 µm are tested and compared,and the influence of diameter on the reinforcement effect of fiber in the mixture is analyzed by slip theory.The results show that basalt fiber with different diameters can enhance the high temperature,low temperature and crack resistance of asphalt mixture to var-ying degrees.Under the same content of basalt fiber,the smaller the diameter of the fiber,the more obvious the enhancement effect on asphalt mixture.This is due to the fact that when the fiber diameter is smaller,the slip ratio is smaller and the performance enhancement of the mixture is bet-ter.
