Beschreibung
Zusammenfassung:	The invention discloses high fluidity grouting modified asphalt and a preparation method thereof. The high fluidity grouting modified asphalt comprises, by mass, 38.5%-63.55% of matrix asphalt, 30%-50% of C9 petroleum resin, 1%-3% aromatic oil, 4%-6% a SBS modifier and 1.5%-2.5% of hydroxyethylethylene bis-stearamide. The high fluidity grouting modified asphalt has high hardening strength, good stability and good flow performances. 本发明公开了种高流动度注浆改性沥青及其制备方法，其以质量百分数计包括以下组分：38.5％～63.5％的基质沥青；30％～50％的C9石油树脂；1％～3％的芳烃油；4％～6％的SBS改性剂；1.5％～2.5％的羟乙基乙撑双硬脂酰胺。本发明的高流动度注浆改性沥青硬化强度高、稳定性好、流动性能好。
