Abstract

Abstract: Branched modifier BM and linear modifier LM are used to modify three kinds of domestic base bitumen KL, PJ, LL. Effect exerted by structural type of SBS on high temperature stability, resistance to fatigue cracking and resistance to low temperature cracking of base bitumen is discussed from the meaning of rheology.

Key words: SBS, modified bitumen, high temperature stability, fatigue cracking, resistance to low temperature cracking

摘要： 采用星型改性剂BM和线型改性剂LM,对KL、PJ、LL三种国产基质沥青进行改性研究,从流变学意义上探讨了SBS的结构类型对基质沥青的高温稳定性、抗疲劳开裂能力、低温抗裂性能的改善效果.

关键词: SBS, 改性沥青, 高温稳定性, 疲劳开裂, 低温抗裂性能
