冻土地区水泥稳定粒料混合料收缩性能的研究

Research on the shrinkage performance of cement treated sand-gravel in the longtime frozen earth district of altiplano

通过室内及实际自然环境中所做的收缩试验,分析了水泥稳定粒料混合料在多年冻土地区特殊环境中的收缩情况及主要影响因素,并研究了抗冻剂的使用效果。

Based on the shrinkage experiment in lab and practical environments , the shrinkage performance and important influencing factors of cement treated sand - gravel in the longtime frozen earth district of ahiplano are analyzed and the practical effect of counter - frozen is studied.
