摘　　要：为了更科学、精准地完成公路路面设计工作,定量分析回弹模量路基参数与公路路面设计的关系,更精准地测算和衡量路基参数对公路路面设计的影响,全面提升公路设计水准,本文首先从回弹模量概念出发,其次提出了基于回弹模量的路基设计PFWD测试法及参数评估标准,最后采用实际工程的模拟测试实验结果衡量了回弹模量参数变化与公路路面设计之间的关系,从而分析了不同参数下路面设计各层级稳定性的变化。In order to complete highway pavement design more scientifically and accurately,quantitative analyze the relationship between resilience modulus subgrade parameters and highway pavement design,so as to more accurately actualize and measure the influence of subgrade parameters on highway pavement design,and comprehensively improve the level of highway design,this paper firstly starts from the concept of resilience modulus,and then proposes the PFWD method of subgrade design and parameter evaluation criteria based on resilience modulus,finally,simulation experiment test results of practical engineering are used to measure the relationship between the change of resilience modulus parameters and highway pavement design,so as to analyze the change of stability at each level of pavement design under different parameters.
