摘　　要：对不同粒径再生骨料混合料击实试验结果进行研究,分析对最优含水率w opt及最大干密度ρmax的影响因素。在骨料含量、水泥掺量、粉煤灰掺量三个因素作用下,利用正交试验设计进行击实试验,通过极差分析法分析对最优含水率w opt及最大干密度ρmax影响的最显著因素。Compaction test of the recycled aggregate mixture with different particle size was conducted,and the influence factors of the optimum moisture content(w opt)and the maximum dry density(ρmax)were analyzed.Considering such three effective factors including aggregate amount,cement amount and fly ash amount,the compaction test was conducted using orthogonal experimental design.The primary relationship for the influence of the optimum moisture content and maximum dry density was analyzed by the extremum difference analysis.
