摘要
为了研究不同类型的APAO和SBS复合改性沥青结合料常规性能和相容性,进行沥青常规实验和荧光观测实验,并将复合改性沥青性能与SBS改性沥青进行对比。结果表明,不同类型的APAO&SBS复合改性沥青的高温性能、感温性能、抗老化性能和相容性均比SBS改性沥青好,但复合改性沥青之间的性能存在一定的差异,综合对比5种复合改性沥青的常规性能和相容性后,193#型APAO&SBS复合改性沥青的性能最佳。
In order to study the conventional properties and compatibility of different types of APAO and SBS composite modified asphalt binder,the conventional asphalt test and fluorescence observation test were conducted,and the properties of composite modified asphalt were compared with those of SBS modified asphalt.The results show that different types of APAO&SBS composite modified asphalt high temperature performance,thermal performance,ageing resistance and compatibility are better than SBS modified asphalt,but there was some difference of performance between composite modified asphalt,comprehensive compare and contrast the regular performance of 5 kinds of composite modified asphalt and compatibility,193#APAO&SBS optimum properties of composite modified asphalt.
