摘要:In order to accurately evaluate the bearing capacity of asphalt pavement structure, the research group, on the basis of real-time temperature data of five kinds of asphalt pavement structure in Daxin experimental road, obtain the dynamic modulus main curves of various types of pavement materials and FWD dynamic modulus of the load acting frequency through dynamic modulus research in laboratory, and determine the dynamic modulus of the pavement structure material true value. According to the principle of dynamic deflection equivalent, this paper puts forward the evaluation method of predicting the bearing capacity of asphalt pavement based on composite modulus determination, pavement structure inverse calculation and bending stiffness modulus attenuation threshold. The evaluation results of five kinds of asphalt pavement structure bearing capacity of experimental road are consistent with the actual performance, which shows that the evaluation method of bearing capacity of asphalt pavement structure based on dynamic deflection equivalent is reasonable and effective.
