Abstract
Oily-Sludge is a waste that occurs in processing, distributing, and storing petroleum. On the other hand, Buton Asphalt in Buton Island has a natural asphalt content that is not less than 650 million tons, with Buton Asphalt content varies between 10-35% which is equivalent to 170 tons of oil asphalt (Department of Public Works, 2010). The problems faced by the asbuton pavement as a binder is the quality of asphalt concrete produced cannot yet compete the oil asphalt pavement as a binder. In this study, a test is conducted to identify the behavior and characteristics of Marshall and dynamic stability on the mixture of Asphalt Concrete – Wearing Course (AC-WC) with the use of asbuton as binder and OS as the rejuvenation material of asbuton. The variation of asphalt content used are 4,5%, 5%, 5,5%, 6%, and 6,5%. Based on the result of the test, the dynamic stability value of asphalt and asbuton mixture that has been rejuvenated has a higher value than the mixture without asbuton.
