This study investigates the use of bio-asphalt, derived from coconut shell (BioCS) and straw (BioST) as an additive to determine its benefits in asphalt mixtures containing reclaimed asphalt pavement (RAP). The study was conducted by determining and comparing the laboratory performance properties of four mixtures and the binders extracted from the mixes. The four mixtures evaluated in this study included 30% RAP mixtures with and without bio-asphalt (BioCS and BioST) and comparable virgin mix. The result showed that bio-asphalt was effective in improving mixture performance of 30% RAP mix close to those of the virgin mix.
