Zusammenfassung:	To provide a modified asphalt waterproof sheet including a modified asphalt composition layer and a polyvinyl chloride sheet layer, the modified asphalt waterproof sheet capable of preventing the softening of the modified asphalt composition layer.SOLUTION: A modified asphalt waterproof sheet 20 includes: a modified asphalt composition layer 2; and a polyvinyl chloride sheet layer 10 that includes a polyvinyl chloride sheet 6 formed over the modified asphalt composition layer 2. The polyvinyl chloride sheet 6 has an amount of volatilized substance of 5.0 g/m2 or less when the polyvinyl chloride sheet 6 is heated at 80°C for 2 weeks.SELECTED DRAWING: Figure 1 【課題】改質アスファルト組成物層とポリ塩化ビニルシート層とを備える改質アスファルト防水シートにおいて、改質アスファルト組成物層の軟化を抑制することが可能な改質アスファルト防水シートを提供すること。【解決手段】改質アスファルト防水シート２０は、改質アスファルト組成物層２と、改質アスファルト組成物層２上に設けられた、ポリ塩化ビニルシート６を含むポリ塩化ビニルシート層１０とを備える。ポリ塩化ビニルシート６は、ポリ塩化ビニルシート６を８０℃で２週間加熱したときの揮発物質の量が５．０ｇ／ｍ２以下である。【選択図】図１
