Semi extraction type of Asbuton product is available as known as modified Buton asphalt (MBA). Research and development have been conducted to obtain better quality of MBA based asphalt concrete. The utilization of Gondorukem (Regina Colophonia) is expected can increase several parameters such as Marshall stability and indirect tensile strength (ITS) of asphalt concrete. The national and regional road infrastructure development in Indonesia can be sustained by used MBA as binder and Gondorukem as additive in pavement material. The aim of this study is to investigate the properties of asphalt concrete wearing course (AC-WC) mixture using MBA as binder and Gondorukem as additive. The result of Marshall stability and ITS tests showed the sufficient of Marshall stability and ITS can be established by proper aggregate interlocking and adhesive which developed due to the utilization of MBA and Gondorukem in AC-WC mixture.
