| 摘 要： | 设计了5种连续级配的沥青稳定碎石配合比，并采大马歇尔试验对混合料性能进行检测，结果表明空隙率和饱和度在确定沥青稳定碎石混合料最佳沥青用量时起主要作用；不同级配对混合料的各项性能均有一定的影响．在进行配合比设计时要找出最佳级配曲线。

| Abstract: | In this paper,mixture performance of 5 kinds of continuons grade asphalt treated mixture is tested by large scale Marshall test. The results show that porosity and saturation play on important role in the determination of optimum asphalt content. Different grade show certain effects on the performance of mixture, so the optimum grade curve is important in mix design. |
