## Abstract
This research is part of an effort to advance the use of Buton rock asphalt (EBBRA)-an asphalt emulsion derived from extracted bitumen-as a binder.EBBRA, or extraction bitumen Buton rock asphalt, consists of 70% mineral and 30% asphalt.To produce bitumen emulsion, cationic emulsion, kerosene, hydrochloric acid, calcium chloride, and water are combined with the bitumen extracted from EBBRA.Coarse, fine, and filler aggregates are then mixed with the EBBRA-based asphalt emulsion to create an Asphalt Concrete Wearing Course (AC-WC) mixture.Marshall specimens are used to measure the stability of this EBBRAcontaining asphalt emulsion.Test results indicate that bitumen emulsions made with EBBRA deliver asphalt concrete mixes with high stability, satisfactory flow, and a favorable Marshall Quotient (MQ).Moreover, increasing curing time improves stability and reduces flow across all emulsified asphalt mixtures.This study emphasizes the use of environmentally friendly materials, including Buton asphalt and other locally sourced materials from Indonesia.By utilizing Buton asphalt, Indonesia could potentially reduce its reliance on imported petroleum bitumen.
