Modified-Asphalt Concrete Composition for Railroad and Constructing Methods Using Thereof
The present invention provides a modified asphalt concrete composition for railway and a construction method thereof. According to the present invention, the modified asphalt concrete composition comprises with respect to 100 parts by weight of asphalt: 1 to 25 parts by weight of styrene-isoprene-styrene; 1 to 25 parts by weight of hydrogenated petroleum resin; 500 to 2,000 parts by weight of aggregates; 10 to 90 parts by weight of fine powder aggregates; 0.5 to 10 parts by weight of a modifier; 0.5 to 25 parts by weight of ethylene-propylene copolymer; 0.1 to 2 parts by weight of cellulose fiber; and 0.1 to 2 parts by weight of an antioxidant. Accordingly, the modified asphalt concrete composition for railway provides high coagulation force and high binding force, thereby providing effects of good durability and easily performing base pavement on a railway track bed at low cost without easily generating plastic deformation, aging, and/or defoliation.
본 발명은 아스팔트 100중량부 기준으로, 스티렌이소프렌스티렌 1 내지 25중량부; 수소가 첨가된 석유수지 1 내지 25중량부; 골재 500 내지 2,000중량부; 미분말 골재 10 내지 90중량부; 개질제 0.5 내지 10중량부; 에틸렌-프로필렌 공중합체 0.5 내지 25중량부; 셀룰로오스 섬유 0.1 내지 2중량부; 및 산화방지제 0.1 내지 2중량부를 포함하는 개질아스팔트 콘크리트 조성물 및 이를 이용한 시공방법을 제공한다. 본 발명에 따른 철도용 개질아스팔트 콘크리트 조성물은 고응집력과 고결합력을 구비하여 내구성이 좋고, 소성변형, 노화 및/또는 박리가 쉽게 발생하지 않으면서도, 철도용 도상에 저비용으로 용이하게 기초 포장을 수행할 수 있도록 하는 효과가 있다.
