摘要
针对上海某地区积存的大量工程渣土,提出应用固化剂稳定工程渣土作为道路底基层、路基的技术方案,以强度及耐久性为关键控制指标,分析不同类型固化渣土路用性能。试验结果表明,固化渣土可以满足不同等级道路底基层、路基的性能要求,并具有较好的水稳定性,可以用作道路底基层、路基填料。
Regarding the large amount of waste soil from infrastructure construction,this paper proposed an ideal recycling method by stabilization and reutilization in pavement subbase and subgrade.Performance of multiple stabilized waste soil was studied with strength and durability as key parameters.The laboratory test results suggested that such stabilized soil can meet the requirements of subbase and subgrade of different levels of pavement and exhibited fair water resistance,which could be used to fill subbase and subgrade.
