Currently many Asbutonpavmenttechnologies were developed. However, investigation of the effect of Asbuton bitumen on asphalt binder rheology is very limited. Because asphalt binder rheology is very important in analyzing road pavement, this paper exhibits the investigation results of the effect of Asbuton bitumen content on asphalt binder rheology. The method in this study is by testing and analyzing the rheological characteristics of asphalts that consist of 0%, 25%, 50%, 75% and 100% Asbuton bitumen. The results were indicated that higher Asbuton bitumen content caused the binder become more elastic, more viscous, more resistant to rutting, and less resistant to fatigue. Eventhough less resistant to fatogue, until 50% Asbuton bitumen is resist to fatigue because the various temperature there is not fatigue factor values (G*sin[ ]) more than 5,000 k Pa.
