红粘土路用性能及施工技术分析

红粘土是一种特殊的路基填筑材料,具有高含水率、高液限、高塑性、高孔隙比等特殊的工程性质,在路基施工中很难压实。目前,国内利用红粘土修筑路堤技术仍不完善,且在后续的公路建设中,还将存在大量红粘土筑路技术方面的问题。因此,在总结众多学者研究的基础上,结合洞新高速的红粘土地区建设项目,通过红粘土土样的室内与现场试验,综合分析红粘土的主要特性、填筑方案、机具组合以及施工工艺,为红粘土路堤施工提供参考。

On red clay road performance and its construction technology

Red clay is a special kind of subgrade filling materials, with high moisture content, high liquid limit, high plasticity, and high porosity. But the compaction in subgrade construction is quite difficult. At present the domestic use of red clay in subgrade construction is still not perfect in the technology, and in the follow up highway construction, it will have lots of technical problems. Based on the studies of many scholars, combined with the red clay area in the Dongxin highway construction project, analysis is made on the red clay samples, mainly including the performance of red clay, filling scheme, machinery combination and construction technology, and the results can be coveied by the other red clay embankment construction.
