摘要
稳定型橡胶改性沥青混合料的设计决定了其技术性能和使用效果的优劣。文章通过室内试验,设计并测试了SMA-13稳定型橡胶改性沥青混合料的路用性能和力学性能,并与常用的SBS改性沥青混合料进行了对比分析评价。结果表明:稳定型橡胶改性沥青的性能分级为PG 76-28,优于常用的SBS改性沥青;稳定型橡胶改性沥青混合料的动稳定度和破坏应变分别提高了18.5%和12.8%,表明其在高、低温性能方面均具有优势。
Technical properties and application effects of stabilized rubber modified asphalt（ SRMA）mixture are decided by its mix design. In this paper,SMA-13 asphalt mixture with SRMA was designed and its performance and mechanical properties were evaluated based on experimental research,and the test results were analyzed on the basis of comparison with that of SBS modified asphalt mixture.. Result shows that the Performance Grade（ PG） of SRMA was PG 76- 28,which is better than that of SBS modified asphalt. The dynamic stability and fracture strain of SRMA mixture increased by 18. 5% and 12. 8% respectively,than that of SBS modified asphalt mixture,showing its superiority in aspects of high temperature and low temperature performance.
