摘　　要：对砂砾石-粘土混合料按砂砾石和粘土不同级配不同配合比的情况进行了击实试验研究;得到砂砾石含量对混合料的最佳含水量及最大干密度的影响特征,及其不掺土的砂砾石料的击实特性.Based on heavy compaction test methods in civil test methods standards, compaction tests on grit-clay mixture are studied according to different gradation of grit, and different proportion between grit and clay. Effects on optimum water content and maximum dry density of grit-clay mixture by grit content, as well as compaction characteristics are obtained.
