摘　　要：沥青的抗紫外光老化性能是影响沥青路面长期服役寿命的重要因素。随着国际上长寿命沥青路面理念的提出,为保证沥青路面具有良好的长期服役性能,亟需提高沥青的抗紫外光老化性能。总结归纳了国内外常见的沥青抗紫外光老化方法,评价了不同方法对沥青抗紫外光老化性能的改善效果,并论述了每种抗紫外光老化方法的优缺点及改进措施,以期为提出更加高效的沥青抗紫外光老化措施提供一定的借鉴意义。这对于我国强紫外线辐射地区沥青路面的建设与使用具有重要的理论与现实意义。The ultraviolet （UV） aging resistance property of bitumen is one of the significant factors in- fluencing the bituminous pavement＇ s service life. With the idea of long - life asphalt pavement in the world,it is urgent to improve the UV aging resistance of asphalt to ensure that asphalt pavement have long service life. Based on the conclusion of the existing methods tor improving the UV aging resistance of asphalt home and abroad, the improvement effect of each method is evaluated in this paper. The advantages and disadvantages of each method are elaborated, and suggestions are also given in order to provide guidance for more efficient methods. It is of great theoretical and practical significance tor the construction and use of asphalt pavement, especially in the strong UV radiation areas of China.
