高塑性黏土填筑高等级公路路堤技术尝试

按公路规范要求,高塑性黏土不能满足高等级公路对填料强度的要求。介绍了对这类土在不掺改良剂的情况下,利用其路堤填筑技术的室内研究和现场试验方法,通过控制其击实功、改进施工工艺增大其稳定性和强度,使所填筑的路堤质量满足设计要求,同时提出了控制填筑质量的压实标准和施工工艺要求。

Technical Exploration of Filling Embankment of High-grade Highway with High Plastic Clay

According to road specifications,high plastic clay cannot meet the requirement of high-grade highway for strength of filling materials.This article introduces the laboratory study and field test methods of embankment filling technology,through which we can increase the stability and strength of this kind of clay without mixing with modifiers and get the quality of filled embankment up to design specifications by controlling its compaction function and by improving the construction process.This article also presents the compaction standard and the construction process requirement for controlling the quality of filling.
