摘要
离析问题是工程施工中遇到的普遍问题,虽然不能彻底消除,但可以通过采取各种措施予以改善和减少。对于水稳层而言,离析有级配离析、含水量离析、水泥剂量离析、压实度离析等类型,其中级配离析影响环节最多,表现形式也多样。从配比设计、集料堆放、拌和、运输、摊铺、碾压六大环节进行分析,提出离析预防措施。
The segregation problem is a common problem existing in the engineering construction. It cannot be eliminated thoroughly, but can be improved and reduced by various measures. For the water stabilized layer, the segregations are the types of graduation segregation, water content segregation, cement dosage segregation and compression segregation, in which the graduation segregation mostly influences on the links and expresses the forms of diversity. The article analyzes six links of mixing ratio design, aggregate piling up,mixing, transport, paving and rolling, and put forward the preventive measures of segregation.
