摘 要：
运用自主提出的"多因素多水平可视化设计方法"安排4种不同粒径的石料和粉料按比例混合,实施试验,对马歇尔稳定度性能指标进行了研究,并用"多因素多水平可视化分析"方法对多维空间试验数据进行分析,得到沥青混合料配合比的最佳工艺范围:C1>51%、30%6%、O/S<5.8%。验证试验:C1=52%、C2=31%、C3=2%、C4=6.5%、M=3%、O/S=5.5%条件下,马歇尔稳定度值达到25.671kN,可见优化区域可信有效。
Method of muhifactor and multilevel visual design presented by our research group was used to arrange the experiments with proportion of stone of 4 different sizes and mine. The experiments were carried out and the Marshall Stability was investigated. The multifactor and multilevel visual analysis was applied in the analysis of multidimensional data of experiment, the best formula of asphalt mixture and the ratio of stone was found and its optimized ranges were as follows： C1 〉51%, 30% 〈C2 〈35%, C3 〈5%, C4 〉6%, O/S 〈5.7%. The verification test： C1 =52%, C2 =31%, C3 =2%, Cd =6.5%, M =3%, O/S =5.5%, the Marshall Stability reached25. 671kN. The optimized area is credible and effective.
