Residual Life Evaluation of Pavement Structure Based on Material Performance
In order to evaluate the remaining service life of asphalt pavement of expressway in service and put forward a reasonable structural reinforcement scheme,based on the fatigue cracking model of inorganic layer and the permanent deformation model of asphalt layer,this paper evaluates the remaining life of the corresponding structural layer through modulus measurement and inversion modulus reduction.Finally,according to the structural reinforcement analysis,the requirements of overlay modulus and rutting resistance per-formance are clarified,and the application demonstration is given in combination with the project.The results show that the proposed fa-tigue cracking model of inorganic layer and permanent deformation model of asphalt layer can effectively evaluate the remaining life of expressway in service.
