摘　　要：为了改善沥青混合料的路用性能,解决沥青路面在服务期限内出现车辙、坑槽、裂缝等早期病害问题,采用掺加不同纤维长度和掺量的高聚合物聚酯纤维到沥青混合料中的方法,研究聚酯纤维对沥青混合料路用性能的影响。结果表明,加入聚酯纤维对沥青路面的高温稳定性、低温抗裂性和抗水害性等路用性能都得到了显著提高,掺量少、长度长和掺量多、长度短的纤维提升路用性能的效果相近。In order to improve the road performance of asphalt concrete,solve the rutting on asphalt pavement in the service period,pit slot,crack early disease problem,testing methods such as adding different fiber length and content of high polymer polyester fiber into asphalt concrete are used to study the influence of polyester fiber on pavement performance of asphalt concrete The results show that road performance such as high temperature stability,low temperature crack resistance and resistance to water disasters of the asphalt surface has been improved significantly.The effects of small amount of mixture with long fiber and large amount of mixture with short fiber on pavement performance are close.
