摘　　要：选用合适的当地材料,用经验公式法求出路面水泥混凝土的初步配合比后,再用正交试验设计得出快速修复路面的水泥混凝土最佳配合比。在此基础上测定其抗压强度、抗折强度和劈裂抗压强度。结论为:在3d内混凝土力学性能增长迅速,达到开放交通的要求,试件养护至28d时混凝土强度符合设计强度标准。In this paper,appropriate local materials is selected.First of all,the empirical analysis method is used to get the initial mix proportion of cement concrete pavement,then the orthogonal test method is used to get the best mix proportion of cement concrete pavement.On the basis of the optimum mix proportion of con- crete,this paper researches on concrete compressive strength,folding strength and split tensile strength.It is concluded that the mechanical properties of concrete are increasing rapidly in 3d,which meets the require- ments of open traffic, and the strength of the concrete meets the design strength standard at 28 days.

关 键 词：路面水泥混凝土 最优配合比 力学性能试验
