Joint Injection Compositions for Concrete of Road Having Stylene Isoprene Stylene, Stylene Butadien Stylene, and Petroleum Resin Added Hydrogen and Constructing Methods Using Thereof

摘要

The present invention is based on 100 parts by weight of asphalt, 5 to 50 parts by weight of styrene isoprene styrene; 1 to 20 parts by weight of styrene butadiene styrene; 5 to 30 parts by weight of hydrogenated petroleum resin; 3 to 10 parts by weight of low density polyethylene; 2 to 8 parts by weight of vegetable oil; 5 to 15 parts by weight of waste tire powder; 1 to 5 parts by weight of the mesophilizing additive; 1 to 3 parts by weight of a rubber anti-aging agent; 0.1 to 2 parts by weight of slaked lime; And it provides a joint injection material composition for concrete roads comprising 0.1 to 2 parts by weight of a stabilizer. The joint injection material composition for concrete roads according to the present invention, specifically, the joint injection material composition for concrete roads comprising SIS, SBS and hydrogenated petroleum resin has excellent tensile strength and elongation, so that the length of the concrete road is elongated by heat or By shrinking, it is possible to prevent the length from being slightly changed according to the change of ambient temperature.
