摘要
对于粉性土、粘性土等高等级公路路基的主要填料,主要用干密度比进行压实度控制,不能完全保证路基的强度和稳定性。提出用空隙率法控制路基压实,并与现有的压实度控制方法作了比较,确定了合理的压实标准。实践证明,路基压实用空隙率法控制是切实可行的。
Silt and clay are main fillings of subgrade of high-grade highway, and the compaction control is based on dry density, which can not assure the intensity and stability of subgrade absolutely. So the void ratio control method is put forward, and has been compared with the actual compaction method; reasonable compaction standard is also established. Research shows that void ratio control method is feasible in compaction control of subgrade.
