摘　　要：通过集料黏附性试验、汉堡车辙试验和冻融劈裂试验,分析抗剥落剂对酸性集料花岗岩黏附性及其混合料水稳定性的影响,并对不同类型抗剥落剂的改善效果评价。研究结果表明:抗剥落剂可以有效改善提升花岗岩集料的黏附性等级及其混合料的水稳定性;不同抗剥落剂对花岗岩集料及沥青混合料的改善效果不一。This paper mainly analyzes the effect of anti-stripping agent on the adhesion of acidic aggregate granite and the water stability of the mixture through the aggregate adhesion test,Hamburg rutting test and freeze-thaw splitting test,and improves the different types of anti-stripping agents evaluation.Research indicates:anti-stripping agent can effectively improve the adhesion grade of granite aggregate and the water stability of the mixture;different anti-stripping agents have different effects on the improvement of granite aggregate and asphalt mixture.

关 键 词：抗剥落剂 酸性集料 花岗岩沥青混合料 水稳定性
