PROBLEM TO BE SOLVED: To improve rutting resistance by increasing strength characteristics immediately after road paving, and to improve asphalt mixture flow resistance at high temperature, crack resistance at low temperature, and resistance to scattering of aggregates. Providing a composition. SOLUTION: (A) 75 to 93% by weight of asphalt, (B) 1 to 5% by weight of epoxy resin, (C) 6 to 20% by weight of thermoplastic polymer modified with maleic acid [(A) + (B) + (C) = 100 wt%], wherein the (B) epoxy resin comprises (i) a lower α-olefin, (ii) a lower alkyl acrylate or methacrylate, and (iii) glycidyl acrylate Alternatively, an asphalt epoxy resin composition characterized in that it is a terpolymer made of glycidyl methacrylate, and the terminal of the molecule has a glycidyl group.
