浇注式沥青混凝土因其具有良好的抗流变性,并能够满足防渗、适应变形、耐久性等多方面的优点而被广泛地应用于处于低温环境中的中低高度的土石坝心墙工程中。在进行浇注式沥青混凝土配合比设计时采用正交设计的方法可以实现以最少的试验组数找出满足设计要求的参数指标,并通过方差分析和极差分析来验证试验的水平及试验的精度。 Pouring asphalt concrete is widely used in middle and low height earth-rock dam heart-wall works in low temperature environment because of its good rheological resistance, and can meet the many advantages of impermeability, deformation, durability, etc. . In the design of pouring asphalt mixture design using orthogonal design method can be achieved with a minimum number of test groups to find the parameters to meet the design requirements of indicators and analysis of variance and range analysis to verify the level of the test and test accuracy .
