## Abstract
Abstract This research aims to examine feasibility of local material of limestone as asphalt pavement aggregate and also Buton Granular Asphalt (BGA) was used for petroleum bitumen partial replacement in the Asphalt Concrete Wearing Course (AC-WC) mixture. The research method used is a laboratory experimental. Density of asphalt mix determined by void in mix (VIM) referred to Bina Marga specification, i.e. minimum 2,5%. The results showed that all of the mixtures meet the standard density which compacted by 2 × 75 blows. The secondary density was evaluated by using the specimen compacted with 2 × 200 blows. The secondary density AC-WC mix used limestone and petroleum bitumen pen. 60/70 binder did not meet the Bina Marga requirements, while AC-WC mix used limestone, petroleum bitumen pen. 60/70 and 10,5% BGA satisfied the stipulade of Bina Marga requirements.
