| Abstract: | Based on indoor and site tests, this paper analyzes road performance and construction process of SBS modified asphalt mixture and obtains changing rules of high- temperature stability and low- temperature crack resistance of modified asphalt mixture. The test results show that addition of SBS rubber modifier can greatly improve high-temperature performance of asphalt of original state; and initial pressure temperature plays an important role in construction. Practical engineering applications show that adoption of SBS modified asphalt mixture and its construction process can remarkably improve the quality of asphalt pavement. |
