Zusammenfassung:	The present invention relates to: a modified asphalt composition having excellent storage stability and improved high temperature properties; and a method for manufacturing the same. More specifically, the present invention provides a modified asphalt composition and a method for manufacturing the same, wherein the modified asphalt composition contains: an asphalt mixture comprising vacuum tower bottoms (VTB); a modifier; a cross-linking agent; and 8 to 40 parts by weight of the VTB based on 100 parts by weight of the asphalt mixture, thereby preventing phase separation of an asphalt material during storage of asphalt and improving high temperature properties. 본 발명은 저장 안정성이 우수하며, 고온 물성이 향상된 개질 아스팔트 조성물 및 그 제조방법에 관한 것이다. 본 발명에 따른 개질 아스팔트 조성물은 VTB(Vacuum Tower Bottom)를 포함하는 아스팔트 혼합물; 개질제; 가교제; 및 상기 아스팔트 혼합물 100중량부 기준 상기 VTB를 8~40중량부가 포함됨으로써 아스팔트의 보관시 아스팔트 재료의 상분리가 발생되지 않으며, 고온 물성이 개선되는 개질 아스팔트 조성물 및 그 제조방법을 제공한다.
