Middle Temperature Asphalt Concrete Compositions Having 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 medium-temperature asphalt concrete composition comprising 0.1 to 2 parts by weight of antioxidant and a construction method using the same. The medium temperature asphalt concrete composition according to the present invention, specifically the medium temperature asphalt concrete composition comprising fine powder aggregate of SIS, SEBS, recycled asphalt recycled aggregate and improved aggregate particle size, has good durability, plastic deformation, aging and/or peeling easily. While it does not occur, it is possible to easily perform the pour process at low cost, and has an effect of allowing pouring and/or laying at a lower temperature than the normal asphalt concrete composition.
