本文通过对骨架密实基层进行系统研究,提出优化水泥稳定碎石级配范围,推荐采用振动成型法进行基层混合料试验,通过振动成型方法成型试件,对试件进行无侧限抗压、劈裂强度、干燥收缩、温度收缩和冻融劈裂等试验,验证骨架密实型基层各项路用性能均优于悬浮密实型基层,提出高寒地区抗裂水泥稳定碎石基层抗裂技术。 In this paper, we make a systematic research on the solid base of skeleton and put forward the optimization of grading range of cement stabilized gravel. It is recommended to use the vibration molding method to test the base mixture, shape the specimen by vibration forming method, Crack strength, drying shrinkage, temperature shrinkage and freeze-thaw splitting. The results show that the road performance of the skeleton compact subgrade is better than that of the suspended dense subgrade, and the crack resistance technology of crack resistant cement stabilized aggregate in the alpine region is proposed.
