SIS SBS Waterproof Asphalt Concrete Composition for Overlay Pavement Using Petroleum Resin Added Hydrogen Stylene Isoprene Stylene and Stylene Butadien Stylene and Constructing Methods of Entire Type Waterproof for Cracks of Surface Using Thereof

摘要

The present invention relates to a waterproof asphalt concrete composition, composed of: 5-35 parts by weight of styrene isoprene styrene; 5-35 parts by weight of styrene butadiene styrene; 5-35 parts by weight of petroleum resin adding hydrogen; 500-2,000 parts by weight of an aggregate; 30-150 parts by weight of micropowder aggregate; 0.1-2 parts by weight of recycled rubber powder; 0.5-25 parts by weight of an ethylene-propylene copolymer; and 0.1-2 parts by weight of cellulosic fibers, with respect to 100 parts by weight of asphalt, and also relates to a waterproof integrated bridge surface crack part repairing method using the composition. Therefore, the bridge surface pavement waterproof asphalt concrete composition using hydrogen-added petroleum resin, SIS, AND SBS can have excellent waterproofing properties and durability by having high cohesion and high binding force, avoid easy plastic deformation, aging and/or delamination, prevent infiltrating water and a port hole, prevent salt damage and neutralization, and repair a crack part on a bridge surface in an integrated way without any additional waterproof treatment.
