MODIFIED ASPHALT COMPOSITION FOR WATERPROOF SHEET, AND WATERPROOF SHEET
PROBLEM TO BE SOLVED: To provide a modified asphalt composition for a waterproof sheet that has low viscosity while having low specific gravity.SOLUTION: A modified asphalt composition for a waterproof sheet contains asphalt, a thermoplastic resin, and glass balloons having a residual content after 106 μm sieving of 35 mass% or less, a bulk density of 0.05 g/cm-0.25 g/cm, and a water floating percentage of 30 mass% or more. The modified asphalt composition has a viscosity at 190°C of 3,000 mPa s-10,000 mPa s.SELECTED DRAWING: Figure 1
【課題】低比重でありつつ、低粘度な防水シート用改質アスファルト組成物を提供する。【解決手段】防水シート用改質アスファルト組成物は、アスファルトと、熱可塑性樹脂と、１０６μｍふるい残分量が３５質量％以下であり、かさ比重が０．０５ｇ／ｃｍ３〜０．２５ｇ／ｃｍ３であり、浮水率が３０質量％以上であるガラスバルーンとを含む。防水シート用改質アスファルト組成物の１９０℃における粘度は、３，０００ｍＰａ・ｓ〜１０，０００ｍＰａ・ｓである。【選択図】図１
