摘　　要：通过室内模拟紫外老化试验,研究紫外线老化对沥青路面低温抗裂性和疲劳性能的影响。通过试验分析得出,紫外线老化后沥青路面在低温最大弯拉强度和最大弯拉应变都降低,抗疲劳性能下降。Through indoor simulated ultraviolet aging test,studied the impact of ultraviolet aging on low temperature crack resistance and fatigue performance of asphalt pavement. Through experimental analysis,after ultraviolet aging,low temperature maximum flexural strength and flexural strain of asphalt pavement were lower,anti-fatigue performance degradation.

关 键 词：沥青路面 紫外线老化 低温性能 疲劳性能
