The present invention relates to an asphalt composition for road pavement, a method for producing the same, and a road pavement method, which are excellent in dry strength, water immersion strength and bending strength. [1] An asphalt, a polyester resin, and an aggregate, wherein the polyester resin is a specific polyester, and a ratio of the polyester resin is 2 parts by mass or more and 30 parts by mass with respect to 100 parts by mass of the asphalt. The asphalt composition for road paving, [2] asphalt, polyester resin, and aggregate at 130 ° C. or more and 200 ° C. or less, wherein the polyester resin is the polyester of [1] Obtained by a method for producing an asphalt composition for road pavement, wherein the ratio of the polyester resin is 2 to 30 parts by mass with respect to 100 parts by mass of the asphalt, and [3] the production method of [2]. The road pavement method which has the process of coating the obtained asphalt composition and forming an asphalt pavement material layer. [Selection figure] None |
