摘　　要：研究了用破碎混凝土废弃物部分取代水泥稳定碎石中的集料,通过不同龄期的无侧限抗压强度,干缩试验和抗压回弹模量试验,得出结论:破碎混凝土废弃物可以作为集料用于沥青路面基层。This paper studies that using the broken concrete wastes to replace the aggregates ot cement stabilized macadam partially, through unconfined compressive strength in different ages, dry shrinkage test and compressive modulus of resilience test, finally the conclusion is drawn that the broken concrete waste can be used as aggregate to be applied to the asphalt pavement base course.

关 键 词：废弃混凝土破碎物 沥青路面基层 无侧限抗压强度 干缩试验 抗压回弹模量
