The present invention relates to an asphalt composition for road pavement, which is excellent in drying strength, strength after immersion in water, and bending strength, a method for producing the same, and a road paving method. [1] An asphalt composition for road pavement including asphalt, a polyester resin and an aggregate, wherein the polyester resin is a specific polyester, and the ratio of the polyester resin is 2 parts by mass or more and 30 parts by mass or less based on 100 parts by mass of asphalt; [2] a method for producing an asphalt composition for road pavement, including a step of mixing asphalt, a polyester resin, and an aggregate at 130°C or higher and 200°C or lower, wherein the polyester resin is the polyester in [1], and the ratio of the polyester resin is 2 parts by mass or more and 30 parts by mass or less based on 100 parts by mass of asphalt; and [3] a road paving method including a step of laying the asphalt composition obtained by the method of [2], thereby forming an asphalt paving material layer.
