浅谈集料吸水率偏大的水泥稳定碎石配合比设计

在进行水泥稳定碎石配合比设计时,首先应进行标准击实试验确定该种材料组成的最大干密度及最佳含水量,而试验规程规定在进行水泥稳定碎石标准击实试验时应将未加水泥的试样加水浸润2h以上,这对吸水率偏大的集料来说,会造成试验所得的混合料最佳含水量偏大,从而严重影响到按此最佳含水量成型的试件强度.通过对比试验,得出对于吸水率偏大的...

Mix Design for Cement Stabilized Crushed Stone with Excessive Water Absorption

Before mix design for cement stabilized crushed stone,the maximum dry density and optimum water content of the material composition should be firstly determined by standard compaction test,however,according to the testing procedure regulations,the aggregate sample shall be infiltrated with water for over 2 hours before the standard compaction test,which will cause too large value for the optimum water content of aggregate,which will seriously affect the strength of specimens prepared with this optimum water...
