松花江大顶子山航电枢纽接线公路水泥稳定碎石基层的配合比设计

Mixing Ratio Design for Cement-stabilized Crushed Stone Base Layer for Connecting Highway of Songhuajiang Dadingzishan Navigation-Power Junction

对水泥碎石基层的集料进行了筛分等各种实验,根据实验结果,确定了底基层为悬浮—密实型、基层为骨架—密实型的配合比,在此基础上根据试样的最佳含水量及标准密度确定了底基层、基层的水泥剂量,通过室内、外实验检测,取得预期效果。

Various tests were carried out for the materials of cement-stabilized base layer. According to the test result, we determined the mixing ratios of bottom base layer （float-dense type） and bottom layer （skeleton- dense type）, based on which, we determined further the cement consumption of bottom base layer and base layer respectively according to the optimal water content and standard density of samples. Through lab and site experimental inspection, we obtained the prospective result.
