讨论了直接应用泰波理论指导矿料级配设计的一种方法 ,该方法先计算理论级配 ,然后在半对数坐标中绘出最大密度曲线 ,并在该最大密度曲线图上直接查出各粒径颗粒含量 ,计算出各种集料的比例。该方法简化了级配设计过程。本文中以水泥混凝土和沥青混合料用砂为例阐述了这一设计方法 A method of direct application of Tebo theory to guide gradation design is discussed. The method first calculates the theoretical gradation, then plots the maximum density curve in semi-logarithmic coordinates and directly finds the maximum density curve Particle size of particles, calculated the proportion of various aggregates. This method simplifies the gradation design process. In this paper, cement and asphalt mixture sand as an example to illustrate this design method
