摘要
主要开展了贫混凝土透水基层配合比设计方法的研究.试验中试件采用圆柱状试件,试件采用上置式振动成型,通过试验提出采用体积法设计配合比;借鉴沥青膜的计算方法给出了水泥用量相应计算公式.通过试验得出合理的水灰比可控制范围在0.39～0.41之间.最后给出了配合比设计流程图.
The method of volume is recommended as standard one by research on mixture design of Permeable lean cement base. In experience column experimental sample is produced by libration from down. Through experimentation, the formula of cement dosage is given. Using for reference calculating formula of asphalt fdm, rational range of water-cement ratio should be controlled in 0.39- 0.41, Finally the design flow chart is listed.
