普通沥青及改性沥青混合料抗变形能力的对比分析

Comparison of Rut Resistance Between Mixtures of Conventional and SBS Modified Bitumen

通过对普通沥青混合料和改性沥青混合料在不同温度、不同压力及不同试件厚度条件下所进行的车辙试验 ,对比分析了沥青类型对沥青混合料抗车辙能力所产生的不同影响 ,为工程中沥青的选择及混合料设计提供依据。

The wheel tracking test has been used to evaluate the deformation resistance of asphalt mixtures of Pen60/80 and SBS modified binders. At different temperatures and contact stress,the comparison of rut resistance between two types of mixtures is analyzed.The analysis indicates that SBS modified bitumen can improve the high temperature stability of mixture significantly.
