摘要
为了研究老化对沥青胶浆流变性能的影响,采用了黏度试验及动态剪切试验,测试了不同老化状态(0 h,10 h,20 h,30 h)下沥青胶浆的流变性数据,同时选用不同的粉胶比(0,0.4,0.8,1.2,1.6,2.0)作为对比试验。通过对实验数据的分析,得出了不同老化状态和不同粉胶比对沥青胶浆老化性能的影响。
Different aging levels(RTFOT,PAV-10,PAV-20 and PAV-30 hours) of asphalt binder with various ratio of lime powder(0,0.4,0.8,1.2,1.6,2.0)are considered to investigate the rheological properties of aging asphalt binder.Based on a limited study,test results show that aging time and the ratio of lime powder influence on rheological characteristics of asphalt binder.
