摘　　要：针对北方地区的气候、经济、材料等特点,提出采用减少细粒含量、增大粗料含量的措施来减少半刚性基层裂缝,确定了水泥稳定大粒径砾石级配的范围,并通过室内试验探讨了水泥稳定大粒径砾碎石基层材料的抗裂性能。Aim at the weather, economy, material etc. characteristics of north of China, this paper put forward some measures on reduce cracks of semi-rigidity base course, such as decreasing dosage of granule, increasing dosage of coarse aggregations etc. Put forward the gradation scope of cement mixture of big-size gravel, also discuss the anti-cracking function of cement mixture big-size gravel in laboratory.

关 键 词：砾石 级配 抗裂 温度收缩 干燥收缩
