  • Asphalt restoration agent microcapsule and preparation method and use thereof
    Patent number: 10357752
    Abstract: The present invention relates to the field of road restoration, and discloses an asphalt restoration agent microcapsule and a preparation method and use thereof. The asphalt restoration agent microcapsule includes a capsule core containing an asphalt regenerant and a capsule wall wrapping the capsule core and containing graphene and hexamethoxymethylmelamine resin, wherein a mass ratio of the graphene to the hexamethoxymethylmelamine resin is 0.1:100-7:100, and a mass ratio of the asphalt regenerant to the hexamethoxymethylmelamine resin is 1:1-1:4. The preparation method provided by the present invention adopts specific steps and specific material adding sequences, so that the asphalt restoration agent microcapsule prepared through the preparation method has better stability and electrical conductivity and can be added to asphalt mixtures to prolong the service life of asphalt pavements.
