Abstract
Natural Buton rock asphalt consists of bitumen and mineral onder goes a refinery process to provide extracted bitumen from natural asphalt, subsequently the extracted bitumen is mixed with the petroleum bitumen to produce modified Buton bitumen. In this study modified Buton bitumen was used as bituminous material and mixed with aggregate and filler to produce asphalt concrete binder course (AC-BC) mixture. The were two prepared specimens in this study. Specimens without aging process and specimens subjected to artificial long term aging in the laboratory after aging process completion, tensile strength of specimens with stress strain relationship were evaluated.
