▎ 摘　　要

NOVELTY - Graphene aerogel self-healing asphalt concrete comprises an asphalt mixture matrix and a graphene aerogel shaped asphalt self-healing agent distributed in the asphalt mixture matrix. The carbon nanomaterial is graphene and/or carbon nanotubes. The graphene aerogel matrix is fiber-type graphene aerogel matrix, particle-type graphene aerogel matrix, and/or fiber-type graphene/carbon nanotube composite aerogel matrix. USE - The concrete is useful to electro-thermal self-repairing field (claimed). ADVANTAGE - The concrete has good electrical conductivity and significantly improves the mechanical properties and durability of asphalt concrete, promotes the efficient healing of crack damage of asphalt concrete under the maintenance condition of electrothermal excitation mechanism, improves the self-repair timeliness of asphalt pavement in the actual application process, and greatly improves the service quality and service life of asphalt pavement. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic diagram of the graphene aerogel self-healing asphalt concrete. 1Asphalt mixed material matrix 2Graphene gas gel shaping asphalt self-repairing agent
