骨架密实型水泥稳定碎石组成设计方法研究

通过振实试验确定水泥稳定碎石混合料中粗集料的级配；对不同i值所对应级配的细集料进行强度、CBR、干燥收缩和温度收缩等试验，确定细集料的级配；以强度为指标确定粗、细集料比例，并根据贝雷法参数检验，可确定骨架密实型水泥稳定碎石的集料级配。最后，通过路用性能试验对骨架密实型水泥稳定碎石混合料进行检验的结果表明：骨架密实型水泥稳定碎石混合料的各项路用性能指标均优于规范级配的水泥稳定碎石混合料的性能指标。

Design Method of Cement Stabilized Aggregate of Dense Framework Structure

The vibrating test is used to determine the gradation of the coarse aggregate in the cement stabilized mixture.Corresponding tests about the strength,CBR,dry shrinkage and temperature shrinkage of the fine aggregate with gradations of different i value are conducted to determine the gradation of the fine aggregate.The strength is taken as an index to determine the ratio of coarse aggregate to fine one,examining it with Bailey parameters and finally getting the gradation of the cement stabilized aggregate of...
