Abstract :

Roads are one of the infrastructure that is urgently needed in improving the accessibility of an area and has a crucial role as a connecting infrastructure that facilitates the transportation of people and goods. This road must be able to handle the volume of traffic according to the plan, so planning must ensure smooth transportation. Asbuton can be used as a binding material on road pavements. However, the use of buton asphalt as a road construction material in Indonesia has not had a significant impact on infrastructure development carried out by the government. The purpose of this study is to analyze the characteristics of Marshall’s test value using Buton Granural Asphalt as a substitute for filler and Fine Aggregate in the mixture of Asphalt Concrete – Wearing Course (AC – WC). The type of data used is primary data obtained from laboratory test results and secondary data obtained from SNI Bina Marga 2018 rev.2. The results showed that with the addition of 19% BGA (Buton Granular Asphalt) as a filler and fine aggregate material, the stability of the mixture could be increased up to 2369,8 kg with the addition of BGA, when compared to aggregate without BGA, the stability value was higher. Based on the test of the characteristics of the 0% BGA mixture marshall obtained a density value of 2,304 t/m³, stability of 1240,6 kg, fatigue of 3.4 mm, Marshall Quotient (MQ) of 366,0 kg/mm, VMA of 16,3%, VFB of 76.2%, VIM of 3.9%. Marshall testing on a mixture of 19% BGA obtained a density value of 2325,0 t/m³, Stability of 2369,8 kg, Fatigue of 3.4 mm, Marshall Quotient(MQ) of 697,1 kg/mm, VMA of 15,4%, VFB of 80,0%, VIM of 3.1%.

All test parameters meet the standards set out in the 2018 General Bina Marga specification for revision 2 road and bridge construction work, so that AC-WC asphalt concrete with 0% and 19% BGA substitution can be used.
