Middle Temperature Asphalt Concrete Compositions Having Styrene Isoprene Styrene, Styrene Ethylene Butylene Styrene 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 asphalt, styrene isoprene styrene 1 to 25 parts by weight; Styrene ethylene butylene styrene copolymer 1 to 25 parts by weight; Petroleum resin 1 to 25 parts by weight; Aggregate 500 to 2,000 parts by weight; 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, and improved aggregate particle size, has good durability, without plastic deformation, aging and/or peeling easily, In addition to being able to easily perform the pour process at low cost, there is an effect of allowing pouring and/or laying at a medium temperature that is lower than that of the general asphalt concrete composition.
