摘要

通常认为SBS可以同时改善基质沥青的高、低温性能。以三种常用的国产沥青和一种进口沥青作为基质沥青，采用四种不同的SBS对其进行改性，分别制得成品SBS改性沥青。运用SHRP试验方法中的弯曲梁流变仪(BBR)分别对制得的这些SBS改性沥青的RTFO／PAV残留物的流变特性进行了试验研究。结果表明，用物理意义上的共存共混方法制备得到的SBS改性沥青，其低温等级基本保持在基质沥青的低温等级上，即从流变学的意义上来说，SBS对基质沥青低温抗裂性能的改善效果仍值得探讨。

Abstract

There is a popular opinion that SBS can improve both high and low temperature performance of base bitumen. In this study

four kinds of SBS are used to modify three kinds of common domestic bitumen and one kind of foreign one; some final products of SBS modified bitumen are obtained. The rheological properties of SBS modified bitumen after RTFO/PAV are studied by using bending beam Rheometer (BBR)

which is one of the test methods of SHRP. The results indicate that the low temperature grade of SBS modified bitumen made by physical method is at the same level as that of base bitumen. In other words

the SBS modification effect on low temperature anti-cracking performance of base bitumen still deserves to study from the meaning of rheology.
