摘　　要：为研究沥青稳定建筑垃圾再生集料的路用性能,采用贝雷法确定建筑垃圾再生集料沥青稳定碎石的最优配合比,通过单轴压缩试验、冻融劈裂试验、水稳定试验和车辙试验,研究再生集料中砖砼集料掺量和砖砼比例变化对沥青稳定碎石基层性能的影响。研究结果表明:建筑垃圾再生集料用于沥青稳定碎石基层应控制砖砼集料掺量和砖砼比例;沥青稳定碎石基层中,建筑垃圾再生集料掺量宜小于50%,砖砼比例宜控制在1:4和2:3,其再生混合料的水稳定性能和力学性能均可满足要求且高温性能有所提高。In order to study the pavement performance of asphalt-treated permeable base using construction waste recycled aggregate,the Bailey method was used to determine the optimal mix proportion.A series of trials onasphalt-treated permeable base,such as unconfined compressive strength test,freeze-thaw splitting test,water stability test and rutting test,were done.The influence of parameters of recycled aggregate,such as the mixing amount of brick and concrete,the proportion of recycled aggregate,on pavement performance was analyzed.The results show that,the content and proportion of brick and concrete in recycled aggregate should be controlled.The content of recycled aggregate in asphalt stabilized macadam should be less than 50%,and the proportion of brick and concrete should be controlled from 1:4 to 2:3.Compared with the asphalt stabilized macadam without recycled aggregate,the water stability and mechanical strength can meet the requirement,and the high temperature performance of recycled mixture is improved.
