摘　　要：为提高建筑垃圾整体再生利用率,将渣土类建筑垃圾进行资源化利用,全面分析水泥稳定渣土路用性能,水泥剂量分别取4.5%、5%和5.5%,同时与水泥用量为9%、10%和11%的水泥稳定细粒土进行综合比较,并对其力学性能、稳定性和耐久性等路用性能进行检验。试验结果表明,5.5%水泥稳定渣土可满足道路底基层技术性能要求,具备用于道路工程的可行性。Residue soil construction waste was recycled in order to improve the overall recycling efficiency of construction waste.The paper comprehensively analyzes the road performance of cement residue soil with the cement content 4.5%,5%and 5.5%respectively.At the same time,the cement content is compared with 9%,10%and 11%cement stabilized fine-grained soil.The mechanical properties,stability and durability of the pavement are tested to verify whether it satisfy the performance requirements of the pavement sub-base material.The test results show that 5.5%cement stabilized residue soil can satisfy the technical performance requirements of road sub-base,and it is feasible for road engineering.
