Simulation of Crack Resistance Evaluation Method of Asphalt Mixture Based on CMOD Method
In order to reduce the error between evaluation results and measured results,a method for evaluating the anti-cracking property of asphalt mixture based on CMOD method was proposed.Firstly,we determined the ratio of asphalt mixture,and built a model of finite element calculation for the specimen,thus obtaining a CMOD curve of the specimen.And then,we combined it with the finite model to obtain a CMOD value.Correspondingly,we imported the parameters into the virtual digital test software to determine the relationship between material microstructure and mechanical properties.According to the requirements of asphalt performance,we determined the experimental environ-ment parameters and the anti-cracking property evaluation indicators to complete the evaluation for the anti-cracking property of asphalt mixtures.Finally,a simulation experiment was designed.The experimental result proves that the e-valuation results are basically consistent with the actual results,so this method has high reliability.
