摘　　要：采用紫外线老化试验,选取相同标号、不同油源生产的三种基质沥青,对沥青的组成、常规指标、流变性能及混合料等性能指标进行试验研究。试验结果表明,紫外线老化对90号沥青及混合料性能均有影响,对沥青的组成和流变性能影响明显;经相同条件的紫外线老化试验后,90号沥青抗紫外线老化性能优劣顺序:1号沥青>3号沥青>2号沥青。Three kinds of asphalt with the same grade and different oil origin are selected.The asphalt composition,conventional indicators,rheological properties and the mixture performance are studied by ultraviolet aging test The test results show that ultraviolet radiation aging affects the performance of 90 asphalt and mixture,especially on the composition and rheological properties obviously.After the same ultraviolet aging test,the order of No.90 asphalt ultraviolet resistance follows：No.1 asphalt No.3 asphalt No.2 asphalt
