SEBS Modified-Asphalt Concrete Compositions for Roads Using Styrene Ethylene Butylene Styrene and Constructing Methods Using Thereof
The present invention provides a modified asphalt concrete composition for roads comprising styrene ethylene butylene styrene (SEBS). The modified asphalt concrete composition for roads comprises, based on 100 parts by weight of asphalt: 1 to 25 parts by weight of an SEBS 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; 1 to 10 parts by weight of a modifier; 0.1 to 2 parts by weight of cellulose fiber; 0.1 to 2 parts by weight of wax; 0.1 to 2 parts by weight of an antioxidant; and 0.1 to 2 parts by weight of a stabilizer. The modified asphalt concrete composition for roads according to the present invention, specifically, the modified asphalt concrete composition for roads comprising SEBS has high cohesion and high bonding force and thus has good 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 100중량부 기준으로, 스티렌에틸렌부틸렌스티렌 공중합체 1 내지 25중량부; 석유수지 1 내지 25중량부; 골재 500 내지 2,000중량부; 미분말 골재 30 내지 150중량부; 개질제 1 내지 10중량부; 셀룰로오스 섬유 0.1 내지 2중량부; 왁스 0.1 내지 2중량부; 산화방지제 0.1 내지 2중량부; 및 안정제 0.1 내지 2중량부를 포함하는 SEBS를 포함하는 도로용 개질아스팔트 콘크리트 조성물을 제공한다. 본 발명에 따른 도로용 개질아스팔트 콘크리트 조성물, 특정적으로 SEBS를 포함하는 도로용 개질아스팔트 콘크리트 조성물은 고응집력과 고결합력을 구비하여 내구성이 좋고, 소성변형, 노화 및/또는 박리가 쉽게 발생하지 않으면서도, 침투수 및 포트홀을 방지하고, 저비용으로 타설공정을 용이하게 수행할 수 있도록 하는 등의 효과가 있다.
