摘　　要：针对建筑废料尤其是废弃混凝土的处理问题,将废弃混凝土破碎后的再生骨料按照不同比例与泡沫沥青进行混合,对再生骨料泡沫沥青混合料配合比进行设计,并从干劈裂强度、干湿劈裂强度比等指标对混合料进行路用性能研究,将其用于铺筑道路基层、垫层,从而最大程度地利用建筑废弃混凝土,以达到降低工程成本、生态环保的双重效益。In order to deal with the problem of construction waste,especially waste concrete,the recycled aggregate after crushing the waste concrete is mixed with foamed asphalt according to different proportions,and the mix ratio of the recycled aggregate foamed asphalt mixture is designed.The wet splitting strength ratio and other indicators are used to study the road performance of the mixture,and it is used to pave the road base and cushion to maximize the use of waste concrete in the building to achieve the dual benefits of reducing engineering costs and environmental protection.
