The invention relates to the field of road restoration, and discloses an asphalt restoration agent microcapsule and its preparation method and application. The microcapsule includes a capsule core and a capsule wall wrapping the capsule core, the capsule core contains an asphalt regenerant, and the capsule core contains an asphalt regeneration agent. The capsule wall contains graphene and methylated hexamethylolmelamine resin, the mass ratio of graphene and methylated hexamethylolmelamine resin is (0.1‑7): 100, the asphalt regeneration agent and methylated hexamethylolmelamine resin The mass ratio of the base melamine resin is 1: (1‑4). The preparation method provided by the invention adopts specific steps and a specific order of adding materials, so that the prepared asphalt repair agent microcapsules have better stability and conductivity, and adding them to asphalt mixture can improve the use of asphalt pavement life. |
