摘　　要：路面混合料矿料级配组成设计是工程设计的重要组成部分,传统的试算法和图解法工作量大,易产生误差.针对这种情况,根据实际施工需要建立符合矿料级配设计实际情况的数学模型.此模型不仅以设计级配为目标,还考虑了混合料组成中关键筛孔尺寸的通过率.经过对模型算法1范数和2范数分析比较后,选择对应模型取1范数的算法———线性规划法为路面混合料级配组成设计的优化算法.经实例检验,该方法可用于各类路面混合料级配组成设计.Aggregate gradation of pavement mixture is one of the important parts of the engineering design ,the traditional trial arithmetic and the graphics arithmetic have many disadvantages, especially the tremendous workload, the bad error tolerance. For the practical requirements, this article presents a mathematical model which has a good match with the aggregate gradation design, and not only for the design of grading targets, also consideres a key component mixture sieve size through rate. After analysis of a 1-norm and 2-norm about the model algorithm , linear programming,which is corresponding to the model to take 1-norm algorithm, is chosen for optimization algorithm. The algorithm can be used of all kinds of aggregate gradation of pavement mixture.
