%X Reclaimed asphalt pavement (RAP) lacks the volatility and became very hard over time due to aging effects. Rejuvenation is one of the methods used in the recycling of aged asphalt pavement to recover its original properties. The study aims to investigate the optimum RSO content to rejuvenate aged 60/70 grade binder and study their compatibility as well as microstructural properties of the binders. The conventional tests showed that the more RSO added, the softer the binder becomes. However, referring to the criteria limitations for both softening point and penetration tests for the 60/70 binder, an optimum percentage of RSO which is 3.25 has been determined. The storage stability test on the 0 and 3 RSO-rejuvenated samples show that the properties enhancement by RSO proves the compatibility of the binder. FTIR and GC�MS chemical characterization has shown important functional groups and chemical compounds that improve the volatility and soften the binder to its original properties. The responsible compounds recognized are palmitic acid, aromatics, oleic acid, oleamide, phthalic acid, disulfides, secondary amine, and aliphatic iodo-compound. Rejuvenation of RAP with RSO has had the bee structures, white spots, and peri-phase decreased while the perpetua phase increased through AFM surface analysis. AFM study concluded that the morphological properties of RAP has been altered by RSO rejuvenation. © 2024, Institute of Technology PETRONAS Sdn Bhd.
