摘要：旧水泥路面快速维修是公路养护人员面临的技术难题,而超薄加铺是一种低成本、 高效率的维修方案。为了得到超薄水泥基加铺材料的最优配合比,通过对水泥基胶凝材料体系的强度发展规律和早期水化机制进行分析,确定基准配合比。以水胶质量比、 辅助胶凝材料替代率和胶砂质量比为自变量,采用三因素11组试验的A最优混合设计法(311-A最优混合设计法)对配合比进行优化设计,分析自变量对设计指标抗折强度、 抗压强度以及流动度的影响。通过模拟计算得到3种配合比组合,对3种组合从经济性、技术性和工作性进行综合分析。结果表明:基于311-A最优混合设计法得到的材料最优配合比的水胶质量比为0.32,辅助胶凝材料替代率为15%,胶砂质量比为1.0,力学强度和流动度的预测值与基于室内试验的实测值误差在5%以内。

Abstract：Rapid repair of old cement pavement was a technical problem faced by highway maintenance personnel, and ultra-thin paving was a low-cost and high-efficiency maintenance solution. In order to obtain the optimal mix proportion for ultra-thin cement-based paving materials, based on the analysis of the strength development law and early hydration mechanism of cement-based cementitious material system, the reference mix proportion was determined. Then, the water-binder proportion, auxiliary cementitious material replacement rate and cement-sand proportion were taken as independent variables, and A-optimal mixed design method of three factors and eleven groups of experiments(311-A optimal mixed design method) was used to optimize the mix design. The influence of independent variables on flexural strength, compressive strength and fluidity of design indexes were systematically analyzed. Three mix proportion combinations were obtained through simulation calculation, and a comprehensive analysis was conducted on the economic, technical, and workability aspects. The results show that the optimal mix proportion of material mass percentage obtained by 311-A optimal mixed design method is water-binder proportion of 0.32, auxiliary cementitious material replacement rate of 15% and cement-sand proportion of 1.0. The error of mechanical strength and fluidity between the predicted value and the measured value based on the indoor verification test is within 5%.
