SIS Half-Elastic Modified Asphalt Concrete Composition Using Petroleum Resin Added Hydrogen and Stylene Isoprene Stylene and Constructing Repairing Method of Entire Type Waterproof for Cracks of Surface Using Thereof

摘要

The present invention relates to a semi-elastic modified asphalt concrete composition composed of: 5-35 parts by weight of styrene-isoprene-styrene (SIS); 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; 0.5-25 parts by weight of an ethylene-propylene copolymer; 0.1-2 parts by weight of sodium benzoate; 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 unit repairing method using the composition. Therefore, the semi-elastic modified asphalt concrete composition using hydrogen-added petroleum resin and SIS can have excellent waterproofing properties by having high cohesion and high bonding force, have excellent durability, avoid easy plastic deformation, aging, and/or delamination, prevent infiltrating water and a port hole, prevent salt damage and neutralization, improve viscoelasticity and elasticity, and repair a crack part on a bridge surface in an integrated way without any additional waterproof treatment.
