摘　　要：延迟时间是水泥稳定碎石基层施工关键控制因素。以北京京承高速公路水泥稳定碎石基层为研究对象,通过室外延迟试验,确定了各相关因素对混合料延迟强度的影响,并提出了具体的施工延迟控制时间,其结果可供同类型工程施工参考、借鉴。The delay time is the key controlled factor in the construction techniques of cement stabilized rushed rock base. Taking the actual example as using cement stabilized crushed rock base in the Beijing-Chengde Expressway,through outdoor delay time experiment, the factors which have influenced on the delay compressive strength are analyzed, and the value of delay time which should be controlled in the construction are given . The results can be consulted in the similar projects.

关 键 词：水泥稳定碎石 基层 延迟时间 配合比 抗压强度
