The invention discloses an epoxy-resin concrete repairing material, a preparation method and a usage method. The epoxy-resin concrete repairing material comprises a single-composition epoxy resin and a mineral material with the weight ratio of 10-30:100. Epoxy resin is used to prepare a capsule particle and is separated from a curing agent and the mineral material, thereby facilitating storage and overcoming the problems in the prior art that mixing is needed on site, equipment investment is large and construction is not convenient. When the restoration material is used, an infrared heating and vibration rolling combination technology is employed, and the technology is capable of rapidly breaking the wall of the microcapsule epoxy resin, performing curing reaction and accelerating the reaction, and thus transport is opened after the strength is reached and construction is convenient. An SBS modified asphalt watertight strip is employed as a new-old paving interface seaming material, gives play to good bonding and waterproof effects, and is capable of effectively delaying the secondary cracking time of the seam.
