Modified-Asphalt Concrete Compositions for Pavement of Roads Using Styrene Isoprene Styrene, Styrene Ethylene Butylene Styrene, Recycling Asphalt and Aggregate-powder of Improved Grain Size and Constructing Methods Using Thereof

摘要

The present invention is based on 100 parts by weight of new asphalt, 1 to 25 parts by weight of styrene isoprene styrene; Styrene ethylene butylene styrene copolymer 1 to 25 parts by weight; Petroleum resin 1 to 25 parts by weight; Recycled asphalt recycled aggregate 20 to 70 parts by weight; 500 to 2,000 parts by weight of new aggregate; 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 modified asphalt concrete composition for road pavement containing 0.1 to 2 parts by weight of an antioxidant and a construction method using the same. Modified asphalt concrete composition for road pavement according to the present invention, specifically, SIS, SEBS, recycled asphalt recycled aggregate and fine aggregate of fine aggregate with improved aggregate size, is provided with high cohesion and high bonding strength to provide durability. Good, without plastic deformation, aging and / or peeling easily occurs, there is an effect such as to prevent the penetration and portholes, and to easily perform the pour process at low cost.
