Abstract

Indonesia has natural asphalt known as asbuton. Bitumen content in asbuton varies from 10-40% and even reaches 90% in several areas such as Kabungka and Lawele. Asbuton has a sufficient deposit of approximately 677 million metric tons which is equivalent to 24 million tons of oil asphalt. This study used Scanning Electron Microscopy (SEM) and Electron Dispersive X-ray spectroscopy (EDX) to determine the chemical composition of Buton Granular Asphalt (BGA). A compressive strength test was performed to investigate the effect of using BGA in the asphalt mixture on strain. The EDX analysis results showed that BGA consists of Carbon (C), Oxygen (O), Calcium (Ca), Silicon (Si), Sulfur (S), Fluorine (F) and Aluminum (Al). Carbon which has a content of 43.1% is the most dominant element in BGA, followed by oxygen 38.3% and sulfur 1.5%. The asphalt mixture with 5% BGA showed a 25% increase in compressive strength and a maximum of stress of 3.54 MPa.
