| description | The invention provides an asphalt mixture discrete element model construction method based on intersection discrimination and convex optimization, and the method specifically comprises the steps: 1, setting a designated region in Matlab, and putting aggregate in the designated region; 2, the aggregate contour information is imported into PFC2D, and a polygonal wall corresponding to the aggregate contour is established; step 3, constructing a designated area which is the same as the designated area in the step 1 in the PFC2D to serve as a designated area wall body; the polygonal wall body in the second step is arranged in the wall body of the designated area; then circular particles are generated in the wall body of the designated area and are arranged to be full of the whole wall body of the designated area; step 4, simulating aggregate formed by polygonal walls, and identifying small circular particles outside all the polygonal walls as asphalt mortar particles; and 5, establishing a two-dimensional asphalt |
