摘    要:
给出了骨架孔隙水泥稳定碎石基层材料粗、细集料级配范围、混合料各组成部分配比计算方法以及计算中所需相关参数测试方法。据此设计了骨架孔隙水泥稳定碎石混合料,并利用振动法成型了水泥含量分别为6%、8%、10%的试件进行相应性能测试,试验中还与水泥含量为6%的悬浮密实结构水泥稳定碎石进行了对比。研究结果表明:骨架孔隙结构水泥稳定碎石在保证一定孔隙率的前提下能够满足目前规范对基层材料要求。

关 键 词:骨架孔隙结构  水泥稳定碎石  配比设计  振动压实  路用性能

Abstract:
The article presents gradation band of coarse and fine aggregate,ingredient proportion calculation method and formula parameters testing method,which used in skeleton-pore cement stabilized aggregate material design.On the basis of the test study,skeleton-pore cement stabilized aggregate were designed and the samples using 6%,8%,10?ment were prepared through vibrating equipment in the lab,then several performances were tested,including unconfined compressive strength,split strength,flexural strength,compressive resilience modulus,flexural resilience modulus,thermal contraction performance,dry shrinkage performance and anti-scour performance.Skeleton-pore cement stabilized aggregate could satisfy the demands of current specification with a certain porosity.
Keywords:skeleton-pore structure  cement stabilized aggregate  mixture component design  vibrating compaction  performance test
