Zusammenfassung:The utility model discloses a high-mixing-amount waste asphalt mixture regenerated pavement structure which is of a layered composite structure. The composite material sequentially comprises a first epoxy asphalt regenerated mixture layer, a first water-borne epoxy resin emulsified asphalt bonding layer, a second epoxy asphalt regenerated mixture layer, a second water-borne epoxy resin emulsified asphalt bonding layer and a base layer from top to bottom, epoxy asphalt regenerated mixtures in the first epoxy asphalt regenerated mixture layer and the second epoxy asphalt regenerated mixture layer comprise epoxy asphalt and milling materials, and the mixing amount of the epoxy asphalt accounts for 1.5%-2.5% of the milling materials. According to the high-mixing-amount waste asphalt mixture regenerated pavement structure provided by the utility model, the epoxy asphalt regenerated mixture is paved on the upper surface layer or the middle surface layer of the pavement, and a layered composite pavement structure is
