摘要
骨架密实结构水泥稳定碎石混合料中粗集料的含量增加,实际使用过程中混合料离析的可能性较大。在分析其产生离析的原因后,分别从混合料的材料组成设计、混合料的拌和装车、运输和摊铺等方面提出了改进措施,同时给出了定量评价混合料离析程度的试验方法和相应指标。
Skeleton-closed cement stabilized crush stone mixture contain more coarse aggregate, and more segregation phenomena appear during construction. After analyzing the reason which causes segregation, the paper presents some methods to improve these phenomena from several aspects such as mixture design, mixture blend, transportation and mixture paving. At the same time, a test method is given to assess mixture segregation extent for different construction stage.
