摘　　要：在沥青混凝土中掺加短丝法和长丝切断两种不同方法制备的聚酯工程纤维,并对两种混凝土试块进行残留稳定度实验、冻融循环后的劈裂抗拉性能试验和抗车辙能力试验,发现通过掺加工程纤维后,沥青混凝土的几项重要性能有了显著提高,且两种方法制备的工程纤维的增强效果相近。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.
