抗剥落剂对酸性集料沥青混合料性能影响研究

Research on the Influence of Anti-Stripping Agent on the Performance of Acidic Aggregate Asphalt Mixture

为了分析抗剥落剂对酸性集料(花岗岩)沥青混合料性能改善效果,本文通过粘附性试验、汉堡车辙试验、冻融劈裂试验、低温弯曲试验和四点弯曲疲劳试验,对花岗岩沥青混合料(是否添加抗剥落剂)的路用性能分析评价,研究结果表明:与常规花岗岩沥青混合料相比,抗剥落剂可以有效改善提升花岗岩与沥青的黏附等级和延迟沥青的剥落时间;掺加抗剥落剂后,花岗岩沥青混合料的高温性能、水稳定性、低温性能和抗疲劳性能均有明显提升。

In order to analyze the effect of anti-stripping agent on the performance improvement of acid ag-gregate (granite) asphalt mixture, this paper analyzes and evaluates the road performance of granite asphalt mixture (whether anti-stripping agent is added) through adhesion test, Hamburg rutting test, freeze-thaw splitting test, low temperature bending test and four-point bending fatigue test. The research results show that: compared with the conventional granite asphalt mixture, the anti-stripping agent can effectively improve the adhesion level of granite and asphalt and delay the peeling time of the asphalt;after adding the anti-stripping agent, the high temperature performance and water stability of the granite asphalt mixture performance, low temperature performance and fatigue resistance have been significantly improved.
