Document Type and Number:
WIPO Patent Application WO/2018/134921
Kind Code:
A1
Abstract:
An asphalt composition for road paving which is excellent in terms of dry strength, water-immersion strength, and petroleum-immersion strength; a method for producing the asphalt composition; and a method for paving a road. [1] An asphalt composition for road paving which comprises asphalt, a polyester resin, and an aggregate, wherein the polyester resin has been melt-kneaded and is contained in an amount of 5-50 parts by mass per 100 parts by mass of the asphalt; [2] a method for producing an asphalt composition for road paving, the method comprising the step of mixing asphalt, a polyester resin, and an aggregate at a temperature of 130-200°C, the polyester resin to be used in the mixing step having been melt-kneaded and being mixed in an amount of 5-50 parts by mass per 100 parts by mass of the asphalt; and [3] a method for paving a road, the method comprising the step of applying an asphalt composition obtained by the production method described in [2] above to form an asphalt pavement material layer.
