| 摘 要： | 采用沥青薄膜烘箱试验（TFOT）和紫外线老化试验，对壳牌90号重交通道路石油沥青，以及掺加添加剂后沥青的针入度、软化点、延度和粘度等指标进行了试验研究。试验结果表明，紫外线老化对沥青性能有比较明显的影响作用，但掺加合适剂量的某些添加剂后，沥青性能可以在一定程度上得到改善；此外，通过TFOT还表明紫外线添加剂对沥青热老化也有一定的改善作用。

| Abstract: | Employing the rolling thin film oven test and ultraviolet radiation aging test,the pene- tration index,soft point,ductility and viscosity of AH-90 asphalt and other additives modified asphalt were investigated.The results showed that the ultraviolet radiation aging would greatly effect the per- formance of asphalt,but the performance can be improved to a certain extent by adding some addi- tives.Then,it was also proved that the additives can improve the anti-aging performance of asphalt by the rolling thin film oven test. |
