Zusammenfassung:	To provide a performance-restoring substance, a reclaimed asphalt composition comprising the same, and a reclaimed asphalt mixture containing the asphalt composition.SOLUTION: A performance-restoring substance comprises 25 wt.% or less of saturated hydrocarbon and 60 wt.% or more of aromatic hydrocarbon, where the kinematic viscosity is 80-200 cSt at 60°C, and 5-40 cSt at 100°C, the difference between the kinematic viscosity at 60°C and the kinematic viscosity at 100°C is 75-195, the specific gravity is 0.94-1.00, and the flash point is higher than 250°C. Also provided are an asphalt composition comprising the same and a reclaimed asphalt mixture containing the same.SELECTED DRAWING: None 【課題】性能復元物質、これを含む再生アスファルト組成物および前記アスファルト組成物を含む再生アスファルト混合物を提供する。【解決手段】２５重量％以下の飽和炭化水素および６０重量％以上の芳香族炭化水素を含み、動粘度が、６０℃で８０〜２００ｃＳｔであり、１００℃で５〜４０ｃＳｔであり、６０℃での動粘度と１００℃での動粘度との差が７５〜１９５であり、比重が０．９４〜１．００であり、引火点が２５０℃よりも高い性能復元物質、これを含むアスファルト組成物およびこれを含有する再生アスファルト混合物を提供する。【選択図】なし
