- Abstract
Hot mix asphalt (HMA) with buton granular asphalt has long been known in Indonesia with maximum use of 15%. With this dose, the use of binder asphalt Pen 60/70 is still needed. Bioasphalt is a fraction of bio-oil derived from biomass resulting from the pyrolysis process whose raw materials are coconut shells and straw. This study tries to determine whether the results of the pyrolysis of coconut shells (BioCS) and straw (BioST) can be categorized as bioasphalt. In addition, it also aims to analyze the potential of bioasbuton, namely a binder consisting of BioCS and bitumen of Asbuton B 50/30 (ASB) as a binder in the AC-WC HMA. From this study, it is known that the BioCS and BioST can be categorized as bioasphalt. The addition of bioasphalt to ASB bitumen can produce bioasbuton with different properties from the original asbuton. The addition of 6% BioCS or 8% BioST to ASB bitumen produces bioasbuton with relatively similar properties to Pen 60/70. The effect of BioCS on changes in rheological properties ASB bitumen is stronger than BioST. The use of bioasbuton made from 15% ASB (by weight of HMA) and 25% BioCS (by weight of ASB) can produce an AC-WC HMA which is equivalent to using pen 60/70. Bioasbuton can be used as an alternative binder to substitute the use of Pen 60/70 in HMA.
