At last through at traditional Marshall design method and Superpave pitch that method compound mix material carry on way compares with and analyses with performance, The result shows , adopt and mix thick, detailed piling up and inlay lock cooperate withpitch who proportion compound mix material have high temperature stability and impervious swimming skill can a good one relatively by ore material that characteristic choose according to one, its surface is coarse, and it is better to resist slippery performance.

通过与传统马歇尔方法和Superpave方法设计的矿料级配在其最佳油石比时的物理力学性能对比分析，发现采用本文提出的设计理论和方法所配制的沥青混合料具有良好的抗高温车辙性能、抗渗水性能以及抗滑性能，而且该方法具有工作量小，在实际工程中易于操作等优点，可以广泛应用于我国高等级公路工程建设。
