Abstract Nowadays, road pavement in Indonesia is still dominated by flexible pavement with petroleum bitumen mostly used as a binder. There is a huge deposit of hydrocarbon sedimentary rocks in several areas in Buton Island, Indonesia. One product of Buton natural rock asphalt is refined Asbuton modification which consists of approximately 70% bitumen and 30% minerals. An investigation of the effects of Asbuton modification on the performance of porous asphalt mixture was made using six mixtures based Asbuton modificated were 4.5%, 5.0%, 5.5%, 6.0%, 6.5%, and 7.0%. This paper presents a comparative parallel about resistance to disintegration or cohesion loss from the results of the Cantabro test for raveling resistance. The application of Retona Blend as a binder in the porous asphalt mixture improved the raveling resistance in relationship Asbuton modification content with cantabro loss value.
