The invention discloses a simulation analysis method for cracking of microcapsules in an asphalt mixture mixing process. The simulation analysis method mainly comprises the following steps of: 1) calculating volume parameters of a microcapsule asphalt mixture multi-scale model; 2) estimating equivalent mechanical parameters of microcapsules; 3) calculating equivalent mechanical parameters of asphalt mortar and asphalt mortar; 4) constructing a mixture mixing model; 5) determining mixture optimal mixing parameters; (6) constructing an asphalt mortar aggregate stress model; 7) constructing an asphalt mortar monomer stress model; (8) extracting the maximum normal force borne by the microcapsules in the model based on the monomer stress model, and establishing a microcapsule stress model on the basis of microcapsule material parameters; and 9) determining the stress distribution, the rupture state, the rupture position and the survival rate range of the microcapsules based on the microcapsule stress model.
