摘　　要：为了研究纤维对AC-13C和SMA-13路用性能的影响,采用车辙试验、劈裂强度试验、冻融劈裂试验和构造深度试验,研究了木质素纤维、玄武岩纤维和聚酯纤维对AC-13C及SMA-13沥青混合料高温抗车辙性能、低温抗裂性能、水稳定性能和抗滑性能的影响,并基于试验结果分析了纤维对沥青混合料的作用机理。试验结果表明:与不添加纤维相比,3种纤维均可以有效改善AC-13C和SMA-13的高温抗车辙性能、低温抗裂性能和水稳定性能,但削弱了其抗滑性能,提出了在高温多雨山区,宜采用添加聚酯纤维的SMA-13沥青混合料作为上面层,以提高沥青路面整体性能的结论。In order to study the effect of fiber on the performance of AC-13C and SMA-13,this paper adopts the rutting test,splitting strength test,freeze-thaw split test and structural depth test to study the high-temperature anti-rutting performance and low temperature resistance of lignin fiber,basalt fiber and polyester fiber to AC-13C and SMA-13asphalt mixture.Based on the test results,this paper analyzes the effect of cracking performance,water stability and anti-sliding performance,and the mechanism of fiber on asphalt mixture.The test results show that the three kinds of fibers can effectively improve the high temperature rutting resistance,low temperature crack resistance and water stability of AC-13C and SMA-13,but weaken the anti-sliding performance.In high temperature and rainy mountainous areas,it is advisable to use SMA-13asphalt mixture with polyester fiber as the upper layer to improve the overall performance of the asphalt pavement.
