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. The asphalt composition includes asphalt, a polyester resin, and an aggregate. The polyester resin is a specific polyester, and the amount of the polyester resin ranges from 2 through 30 parts by mass, based on 100 parts by mass of asphalt. The method for producing an asphalt composition for road pavement, includes a step of mixing asphalt, the polyester resin, and an aggregate at 130° C. or higher and 200° C. or lower, wherein the polyester resin is used in an amount ranging from 2 through 30 parts by mass, based on 100 parts by mass of the asphalt. The road paving method including a step of laying the asphalt composition, thereby forming an asphalt paving material layer.
