| 摘 要： | 采用灰色关联分析方法研究了两种复合改性沥青四组分与其5℃延度、软化点、25℃针入度及针入度指数PI之间的关联程度.研究表明,沥青质与各项性能指标的关联程度相对较高,其中与25℃针入度的关联程度最高；两种复合改性沥青中四组分对其性能指标的影响次序比较一致,在不同复合改性沥青体系中具有一定的可拓展性.

| Abstract: | We adopted the theory of grey relation degree to study the composition of two kinds of compound modified bitumen and evaluated its relation degree with ductility at 5 ℃,softening point,the penetration at 25 ℃ and penetration index.The results showed that there was a better relation between the content of asphaltene and the performance indicators of compound modified bitumen,especicially best with the penetration at 25 ℃;the effect of two kinds of compound modified asphalt on its performance index was consistent,which had a certain extension in the different compound modified asphalt system. |
