Research on the Influence of Resilience Modulus Subgrade Parameters on Highway Pavement Design
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.
