| 摘 要： | 根据SHRP沥青胶结料性能分级(PG)方法,对辽宁地区近年来沥青路面常用的AH90#重交基质沥青和SBS改性沥青的性能进行测试和比较。研究表明SBS改性沥青高低温性能优于重交AH90#沥青,SBS改性沥青更适应辽宁的气候和交通要求,改善沥青路面使用性能,延长路面使用寿命。

| Abstract: | The paper introduces methods for performance grading of SHRP bituminous cement(PG method),and makes testing and comparison between AH90# heavy matrix bitumen and SBS modified bitumen for their performances.Research indicates the performances of SBS at high and low temps are preferable to ones of AH90# heavy matrix bitumen;SBS modified bitumen even more suits Liaoning climate and traffic requirements,could improve service properties of bituminous pavement and prolong its service life. |
