Embodiment Construction
[0013] The invention provides a method for analyzing the drainage characteristics of double-layer porous asphalt pavement based on the discrete element method. The specific implementation steps are as follows:
[0014] (1) Design the mix ratio of the asphalt mixture on the upper and lower layers of the double-layer porous asphalt pavement respectively, and determine the gradation of the upper and lower layers of the double-layer porous asphalt pavement, the optimal asphalt ratio and void ratio;
[0015] (2) Through the parameter calibration test, the shear modulus, density, dynamic and static friction coefficient, and collision recovery coefficient of the aggregate on the double-layer porous asphalt pavement and the lower layer are obtained;
[0016] (3) Construct a three-dimensional particle model framework of coarse and fine aggregates with different particle sizes, and import the discrete element software to fill the particle frame to generate coarse and fine aggregate enti...
