A high-grade asphalt composition includes 100 parts by weight of asphalt; 40-80 parts by weight of styrene-isoprene-styrene; 20-60 parts by weight of a polymer resin; 10-50 parts by weight of an anti-rutting agent; 2-15 parts by weight of a filler; 5-30 parts by weight of ceramic nanoparticles; 5-10 parts by weight of a binder; 3-15 parts by weight of an antioxidant; 1-10 parts by weight of a stabilizer; 5-20 parts by weight of a fiber; and 2-20 parts by weight of an adhesion promoter. A construction method is provided using the asphalt composition. The present asphalt composition is not easily rutted, aged and/or stripped. At the same time, the present asphalt can prevent water penetration and potholes, can reduce noise, and enable the roads to be paved at low costs.
