Zusammenfassung:PROBLEM TO BE SOLVED: To provide an asphalt regeneration additive promoting usage of an asphalt pavement waste and enabling resource saving and an asphalt composition containing the same.SOLUTION: An asphalt regeneration additive is obtained by mixing (A) a specific petroleum-based mineral oil of 10 to 70 mass%, (B) aliphatic acid ester of 30 to 90 mass%, (C) a surfactant of 1 to 10 mass%, (D) a rubber emulsified article of 1 to 10 mass%. The asphalt regeneration additive has polycyclic aromatic component of 3 mass% or less, flash point of 250°C or more, kinetic viscosity at 60°C of 80 to 500 mm/s, aromatic component of 15 mass% or less, aniline point of 85°C or less and flow point of -15 or less.SELECTED DRAWING: None 【課題】アスファルト舗装廃材の活用を推進し、省資源化を可能にするアスファルト再生添加剤及びこれを含有するアスファルト組成物を提供する。【解決手段】アスファルト再生添加剤は、(A)特定の石油系鉱油10〜70質量%、(B)脂肪酸エステル30〜90質量%、(C)界面活性剤1〜10質量%、(D)ゴム乳化物1〜10質量%、を混合して得られる。アスファルト再生添加剤は、多環芳香族分3質量%以下、引火点250℃以上、60℃における動粘度80〜500mm2/s、芳香族分15質量%以下、アニリン点85℃以下、流動点−15以下である。【選択図】なし
