摘要
本文用自制的大型击实仪对大粒径碎石土作了试验研究 ,得出了碎石粒径 6 0 mm以下 ,碎石含量为 2 5 %～ 5 5 %情况下碎石土最大干密度与最佳含水量的试验结果 。
On basis of the test on large size crushed stone soil by large compaction instrument, this paper gives test results on maximum dry density and optimum moisture content of crushed stone soil. That is it is better to have the particle size less than 60 mm and the crushed stone content 25 55%. It can serve as a guide for controlling the quality of large size crushed stone soil fill.
