Recycling asphalt technology is a technology that reuses of aged asphalt pavement that has been damaged and recycled as a new asphalt mixture material which in using it requires a modifier to restore the performance of aged asphalt. Bio-asphalt which is a fraction of bio-oil derived from biomass containing lignin has the potential as a modifier/rejuvenator for aged asphalt. The objective of this study is to determine the potential of the bio-asphalt as a modifier. Bio-asphalt modified aged asphalt binder is tested and evaluated based on AASHTO requirements. Best bio-asphalt content is suggested for modifying aged asphalt binder. Bio-asphalt modified aged asphalt binder were tested to know the mechanical properties by dynamic shear rheometer (DSR) temperature sweep test and frequency sweep test. In this study, the bio-asphalt used are coconut shell bio-asphalt (BioCS) and BitutechRAP, each of which was mixed with Aged asphalt binder from recycled asphalt pavement (RAP) extraction and controller asphalt binder use pen 60/70 (PG 64). The result showed that bio-asphalt can improve the mechanical performance of aged asphalt binder close to pen 60/70 as a controller.
