摘　　要：使用破碎河卵石充当沥青混凝土骨料,并将沥青混凝土中部分石粉用水泥代替,添加抗剥落剂等措施来提高二者的黏附性,调整水泥、抗剥落剂的掺量,并通过浸水马歇尔试验、多次冻融劈裂试验等来验证沥青混合料的各项性能是否满足标准要求。Use broken pebble as asphalt concrete aggregate,and some stone powder in asphalt concrete is replacedby cemnt,easures such as adding anti-stripping agent to improve the adhesion,adjust the dosage of cement and anti-stripping agent,and through the immersion Marshall test and freeze-thaw splitting test many times to verify whether the performance of asphalt mixture satisfies the requirement of standard.

关 键 词：破碎卵石 沥青路面 抗剥落性
