| 摘 要： | 采用千分表测量方法,对骨架密实型水泥稳定级配碎石的干缩特性进行了研究。结果表明:水泥剂量、压实度、含水量、环境因素都对骨架密实型水泥稳定级配碎石的干缩特性有重要影响。合理控制水泥剂量、压实度与含水量,可以有效减少水泥稳定级配碎石的干缩开裂。研究结果对于控制半刚性基层开裂有较大的应用价值。

| Abstract: | We study the evaporation shrinkage characteristic of cement stabilized graded stone with framework and dense structure using the micrometer device.The test results show that cement dosage,degree of compaction,water content and circumstance all have important effects on the evaporation shrinkage characteristic of cement stabilized graded stone.Reasonable cement dosage,degree of compaction and water content could reduce the shrinkage crack of cement stabilized graded stone effectively.The results can be of gr... |
