The present invention is based on 100 parts by weight of asphalt, styrene isoprene styrene 1 to 25 parts by weight; Styrene ethylene butylene styrene copolymer 1 to 25 parts by weight; Petroleum resin 1 to 25 parts by weight; Aggregate 500 to 2,000 parts by weight; 30 to 150 parts by weight of fine powder aggregate; Cellulose fiber 0.1 to 2 parts by weight; 0.1 to 2 parts by weight of wax; And it provides a high-grade waterproof asphalt concrete composition comprising 0.1 to 2 parts by weight of antioxidant. The high-grade waterproof asphalt concrete composition according to the present invention has high cohesiveness and high bonding strength, so it has excellent waterproofness, PG grade performance is a common grade with high grade (PG 82-34), good durability, plastic deformation, aging and / Or even if peeling does not occur easily, it has the effect of preventing penetration water and port holes. |
