| Abstract: | The mechanism of asphalt concrete reinforced with polyster-fiber was analysed in this paper.The performance of concrete was tested,including residual stability test,splitting-tensile resistance test after freeze-thaw cycles and rutting resistance test.It was found that the performance of concrete was significantly increased,and the reinforcing effect of two kinds engineering fiber was similar. |
