    • PURPOSE: A water-resistant and root-resistant modified asphalt composition is provided to stably maintain the durability of a building. CONSTITUTION: A water-resistant and root-resistant modified asphalt composition comprises 30-56 weight% oxidation modified asphalt, 1-8 weight% rubber reforming agent, 20-40 weight% plasticizer, 20-40 weight% mineral stabilizer, 2-8 weight% vegetable fiber stabilizer, and 0.3-5 weight% root resistant additive formed by 2-(4chloro-2-methyl phenoxy)-propionicacid octyl ester. The rubber reforming agent is formed by the mixing of one or more rubbers selected from a SBS(styrene butadiene styrene)-based rubber, a SB(styrene butadiene)-based rubber, a SEBS(styrene ethylene butadiene styrene)-based rubber, SIS(styrene isoprene styrene)-based rubber.
