摘要
随着道路交通量增加，轴载和轮胎压力的增大，沥青混合科级配设计方法也有必要更新。本文提出了一种新的沥青混合料设计方法一体积法。根据这种方法设计的沥青混合料粗集料含量高。室内试验和试验路结果表明这种混合料能够提高柔性路面抵抗高温变形的能力，减少低温开裂。当用作表面层时，还具有良好的表面构造和抗滑性及不透水性。
A new method of mixture design - Volume Method of mixture design is presented in this paper. The mixture designed by this method increases the coarse aggregated content compared with the uniformly graded mixture. The results show that this kind of mixture can greatly improve the capacity of the mix to resist deformation and low temperature thormal cracking. In addition, the mixture provides a good skid resistance and waterproofing quality when used as a wearing course.
