MODIFIED ASPHALT CONCRETE COMPOSITION FOR ROAD PAVEMENT USING SIS, SEBS, RECYCLING ASPHALT, AND AGGREGATE POWDER OF IMPROVED GRAIN SIZE AND CONSTRUCTION METHOD THEREOF

摘要

The present invention relates to a modified asphalt concrete composition for road pavement and a construction method using the composition, wherein the modified asphalt concrete composition contains, based on 100 parts by weight of new asphalt: 1 to 25 parts by weight of styrene isoprene styrene; 1 to 25 parts by weight of a styrene ethylene butylene styrene copolymer; 1 to 25 parts by weight of a petroleum resin; 20 to 70 parts by weight of recycled asphalt recycled aggregate; 500 to 2,000 parts by weight of new aggregate; 30 to 150 parts by weight of aggregate powder; 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 modified asphalt concrete composition for road pavement according to the present invention, the modified asphalt concrete composition for road pavement using SIS, SEBS, recycling asphalt, and aggregate powder of improved grain size to be specific, is highly durable by having high levels of cohesiveness and binding force. In addition, plastic deformation, aging, and/or peeling is unlikely to occur, infiltrating water and potholes can be prevented, and a pouring process can be carried out with ease and at a low cost.;COPYRIGHT KIPO 2020
