再生水泥稳定碎石在城市市政道路的应用

Application of Recycled Cement Stabilized Crushed Stone in City’s Municipal Road

结合长沙市匍园路(滨河路—支三路)市政道路路面基层施工,采用建筑固体废弃物再生骨料加原生骨料配制水泥稳定层,代替传统设计的水泥碎石稳定层。工程实践表明,采用再生骨料配制的水泥稳定层,在保证道路工程质量的同时,降低工程成本,而且处理了建筑垃圾,为建筑垃圾的再生利用开辟了另一条渠道。

Combined with the construction of municipal road base of Puyuan Road(Binhe Road-Branch 3 Road)in Changsha City,the cement stable layer is prepared by using the recycled aggregate of construction solid waste and the original aggregate to replace the traditional cement macadam stable layer.The engineering practice shows that the cement stable layer prepared with recycled aggregate not only ensures the quality of road engineering,but also reduces the engineering cost,and treats the construction waste,which opens up another channel for the recycling and utilization of construction waste.
