摘要:
为研究水泥稳定碎石的级配优化设计问题,针对未加水泥的级配矿料,构建矿料间隙率的物理模型,给出骨架密实型级配矿料粗细分界筛孔通过率的计算公式,建立骨架密实型级配设计理论.在考虑细料对粗料排列的干涉作用后,通过试验获得实际意义上的骨架密实型水泥稳定碎石,形成该类材料的级配优化设计方法.结果表明:未加水泥的级配矿料击实试验所得的最大干密度或间隙率可作为判断水泥稳定碎石骨架密实性的简便指标;通过建立的理论模型与优化设计方法,可成功地设计出水泥剂量较低、强度较高的骨架密实型水泥稳定碎石.
Abstract:
In order to investigate the gradation optimization design of cement stabilized macadam, a physical model about voids in the mineral graded aggregate without cement was established. The formula which calculates the passing rate of the particle size between coarse and fine aggregates for the skeleton-density aggregate was presented, and the graded design theory of skeleton density was set up. Considering the interference effect of fine aggregate to coarse aggregate arrangement, the actual skeleton-density graded cement stabilized macadam structure was obtained, and the method of gradation optimization design of this material was formed. The results show that the maximum dry density obtained by heavy compaction test or voids in the mineral graded aggregate without cement can be used as a simple index to determine the skeleton compactness of the cement stabilized macadam. Using the established theoretical model and gradation optimization design method, the skeleton-density cement stabilized macadam with low cement dosage and high strength can be design successfully.
