MARSHALL MIXED CHARACTERISTICS AC-BC USING BUTON GRANULAR ASPHALT (BGA) 15/20 AS MATERIAL COMPOSITION OF FINE AGGREGATE

Abstract

Indonesia has developed an asbuton product that is BGA (Buton Granular Asphalt). BGA can be used in hot mix asphalt and cold mix asphalt. BGA is used as part of the asphalt material that can reduce the use of fine aggregate/sand. However, the use of BGA is still not optimal. The study was conducted to determine the use of the mixture to produce a good composition. The variation percentage of BGA is used 20%, 40%, 60%, 80% and 100% with the addition of bitumen 4.5%, 5%, 5.5%, 6%, 6.5% and 7%. The results of this study showed the addition of BGA can increase stability and decrease the value of AC-BC mixture flow. The best composition is the use of BGA by 40% with the addition of asphalt 5.5% and 6%.
