用系列粘度数据分析SBS改性沥青的结构特点

Microstructure of SBS modified asphalt based on viscosity data

采用Brookfield旋转粘度计,对几种改性沥青高温下的粘度进行了研究,发现不同的改性剂在同一沥青中以及同一改性剂在不同沥青中粘度差异较大。这一结果表明不同改性沥青微观结构是不同的,这种微观结构的差异直接影响着改性沥青的性质。

The viscosity of several modified asphalts at high temperature was measured by Brookfield rotational viscomter. The results show that the viscosity of same asphalts with different modifiers is obviously different from the viscosity of different asphalts with same modifier.Those indicate that the modified asphalts have different microstructures, which directly influence modified asphalts performance.
