SIS Waterproof Asphalt Concrete Compositions Having Urethane Resin Stylene Isoprene Stylene and Aggregate of Improved Particle-Size Distribution and Constructing Methods Using Thereof
The present invention provides a waterproof asphalt concrete composition which comprises, based on 100 parts by weight of asphalt: 1 to 15 parts by weight of a urethane resin; 1 to 25 parts by weight of styrene isoprene styrene (SIS); 1 to 25 parts by weight of a styrene ethylene butylene styrene copolymer; 1 to 25 parts by weight of a petroleum resin; 500 to 2,000 parts by weight of aggregates; 30 to 150 parts by weight of fine powder aggregates; 0.1 to 2 parts by weight of sodium benzoate; 0.1 to 2 parts by weight of cellulose fiber; 0.1 to 2 parts by weight of wax; and 0.1 to 2 parts by weight of an antioxidant. The waterproof asphalt concrete composition according to the present invention, specifically, the waterproof asphalt concrete composition comprising a urethane resin, SIS, and fine powder aggregate having an improved aggregate particle size has high cohesion and high bonding force and thus has excellent waterproof performance, has good viscoelasticity and durability, can prevent plastic deformation, aging, and/or peeling from occurring easily, can prevent infiltrating water and portholes, and can enable a placing process to be easily carried out at low costs.
본 발명은 아스팔트 100중량부를 기준으로, 우레탄 수지 1 내지 15중량부; 스티렌이소프렌스티렌 1 내지 25중량부; 스티렌에틸렌부틸렌스티렌 공중합체 1 내지 25중량부; 석유수지 1 내지 25중량부; 골재 500 내지 2,000중량부; 미분말 골재 30 내지 150중량부; 소듐벤조에이트 0.1 내지 2중량부; 셀룰로오스 섬유 0.1 내지 2중량부; 왁스 0.1 내지 2중량부; 및 산화방지제 0.1 내지 2중량부를 포함하는 방수아스팔트 콘크리트 조성물을 제공한다. 본 발명에 따른 방수아스팔트 콘크리트 조성물, 특정적으로 우레탄 수지, SIS 및 개선된 골재 입도의 미분말 골재를 포함하는 방수아스팔트 콘크리트 조성물은 고응집력과 고결합력을 구비하여 방수성이 우수하고, 점탄성 및 내구성이 좋으며, 소성변형, 노화 및/또는 박리가 쉽게 발생하지 않으면서도, 침투수 및 포트홀을 방지하고, 저비용으로 타설공정을 용이하게 수행할 수 있도록 하는 등의 효과가 있다.
