摘　　要：通过对新旧公路路基路面规范中有关路基顶面回弹模量规定的对比,指出静态回弹模量、动态回弹模量的物理力学意义及试验方法、路基设计状态的区别,以及路基顶面弯沉检测的变化,使工程技术人员加深对现行规范的理解及正确的应用。By comparing the modulus of resilience of subgrade top in the new and old specifications of highway subgrade, this paper points out the physical and mechanical significance and test method of static modulus of resilience and dynamic modulus of resilience, the difference of subgrade design status, and the change of detection for subgrade top deflection, which makes engineers deepen the understanding of current specifications and correctly use the current specification.
