Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a modified asphalt composition for waterproof construction, which is suitable for waterproof construction, exhibits little tackiness in execution, and generates little fuming and odoring in heat melting.SOLUTION: A modified asphalt composition for waterproof construction (conforming to JISK2207 waterproof construction asphalt class 3) is prepared by adding a high-fluidity soft-type polypropylene by a metallocene catalyst, a wax and a SEBS (hydrogenated styrenic thermoplastic elastomer) and the like to a straight asphalt, and generates little fuming and odoring in heat melting and exhibits little tackiness in execution.
