摘　　要：在江苏省沿海地区土质主要为粉土和粉质黏土,土性较差,这对修建高速公路路基非常不利,尤其上路床对承载力要求较高。针对这种土质仅采用石灰处治,早期强度较低,为保证施工质量,增强填料的结合性能,对高速公路上路床填料采用4%石灰+2%水泥综合处治土填筑。本文对水泥石灰综合处治土施工工艺控制进行了探讨,以供大家参考。In the coastal areas of Jiangsu Province,the soil is mainly silt and silty clay,which has poor soil properties,which is very unfavorable for the construction of highway subgrades,and especially the roadbed requires higher bearing capacity.For this kind of soil,only lime treatment is adopted,and the early strength is low.In order to ensure the construction quality and enhance the binding performance of the filler,the roadbed filler on the expressway is treated with 4%lime+2%cement comprehensive soil treatment.This article discusses the construction process control of cement lime comprehensive treatment,for your reference.
