摘　　要：为了提高沥青混合料矿料级配计算精确度和效率,设计了一种矿料级配计算模型:SG法,包括数据预处理、优化组合、比例计算、评分四个环节,编制了具有自动计算功能的计算机程序,基于AC-25级配将SG法的计算结果与现有方法进行对比。结果显示:SG法的计算结果优于规划求解法和Linest法,与拉格朗日法相仿,但SG法能够一次给出多组最优结果;且该方法在最佳级配选择时综合考虑了曲线范围、贝雷评价、合成值与中值差值等人工经验,比采用数学方法计算得到的结果更有实际应用价值。A calculating model of mineral aggregate gradation is designed in this paper,which includes four links:data preprocessing,optimizing combination,proportion calculation and grading.The calculating results of SG method are compared with those of existing methods based on AC-25 gradation.The results show that the calculation results of SG method are better than those of other methods,and the method takes human experience into account when choosing the optimal gradation,which has more practical application value than the results calculated by mathematical method.
