摘要
采用SHRP关于沥青胶结料性能分级(PG)方法,对辽宁地区近年来沥青混凝土路面常用的AH90号重交基质沥青和SBS改性沥青的性能等级进行研究。研究表明SBS改性沥青高低温性能优于重交AH90号沥青,SBS改性沥青适应辽宁的气候和交通要求,改善沥青混凝土路面使用性能,延长路面使用寿命。
The performance grades of original asphalts and SBS modified asphalts in the regions of Liaoning Province are studied using asphalt binder performance grade method of SHRP in this paper. The results indicate that the high-temperature and low-temperature properties of SBS modified asphalts are better than the original ones. And SBS modified asphalts are available for the climate of Liaoning Province and traffic volume.
