水泥稳定碎石基层是我国高速公路常用的承重结构层，由于水泥用量不合理、施工工艺不科学，新建基层常常出现开裂情况，进而降低了道路的使用寿命。采用新水泥碎石混合料 CBG —25断级配设计理论，计算出水泥稳定碎石混合料的级配组成；并通过不同级配和水泥剂量的无侧限抗压强度试验，且在此基础上研究了级配和水泥剂量对混合料强度的影响规律，结合实体工程实施效果阐述了水泥稳定碎石现场施工的控制要点。

Cement stabilized macadam base layer as a load-bearing structure is widely used in our highway.The new cement stabilized macadam base often cracks because of unreasonable amount of ce-ment and unscientific construction technology,which reduces the life of the road.In this paper,a new cement gravel mix CBG—25 off grading design theory is used to calculate the composition of cement stabi-lized gravel mixture gradation,and the influence rule to cement mixture strength by gradation and cement dose was investigated through different gradations and cement dose unconfined compressive strength test, combined with effects of physical implementation of real project,the construction site control points of cement stabilized gravel were elaborated on the basis of them.
