| 摘 要： | 采用沥青薄膜加热试验和紫外线老化试验，对沥青的针入度、软化点、延度和粘度等性能指标进行了试验研究。试验结果表明，紫外线老化对重交通道路沥青、SBR改性沥青和SBS改性沥青的性能都有影响，但是相同条件的紫外线老化后，SBS改性沥青的低温性能最好。

| Abstract: | By thin film oven test and ultraviolet photooxidation test, asphalt performance indices were studied, including penetration, softening point, ductility and viscosity. The result showed that performances of heavy traffic road asphalt, SBR modified asphalt and SBS modified asphalt were influenced by ultraviolet photooxidation, but after the same ultraviolet photooxidation, low-temperature performance of SBS modified asphalt was best among the three kinds of asphalt. |
