Modified-Asphalt Concrete Compositions for Pavement of Roads Using 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 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 modified asphalt concrete composition for road pavement comprising fine powder aggregate of SIS, SEBS, and improved aggregate size, has high cohesiveness and high bonding strength, has good durability, plastic deformation, It is effective in preventing aging and/or peeling easily, preventing infiltration water and portholes, and easily performing a pour process at low cost.
