The invention provides water-borne acrylic resin emulsified asphalt concrete which comprises mineral aggregate and water-borne acrylic resin emulsified asphalt which are mixed and stirred together, wherein the weight part ratio of the mineral aggregate to the water-borne acrylic resin emulsified asphalt is 100:(5-40). The water-borne acrylic resin emulsified asphalt concrete is prepared by the steps of preparing the water-borne acrylic resin emulsified asphalt by a one-step method, adding the water-borne acrylic resin emulsified asphalt into the mineral aggregate, stirring uniformly and performing maintenance. The water-borne acrylic resin emulsified asphalt concrete prepared by the invention has the advantages of the traditional cold-mixing asphalt concrete, has excellent mechanical property, stability and pavement performance, greatly prolongs the service life of a road surface, has short maintenance time, namely traffic can be opened after 1-day to 3-day maintenance, and can be applied to preparation of asphalt concrete paving materials, asphalt pavement patching materials, a maintenance thin pulp sealing layer, micro-surface and high-speed railway asphalt mortar.
