Abstract:
The reuse of reclaimed asphalt pavement (RAP) offers an effective solution to reduce construction costs, energy consumption, and emissions. This study investigates bio-oil/RAP-based recycled asphalt pavement (BORAP) using bio-oil as a rejuvenator and graphene oxide (GO) to enhance mechanical performance, replacing high-modulus additives. Tests identified 70% RAP as the optimal content, achieving peak dynamic modulus and rutting resistance. A life cycle assessment revealed that 70% RAP reduced total embodied energy (TEE) and greenhouse gas (GHG) emissions by 41.48% and 41.59%, respectively, compared with hot-mix asphalt (HMA). BORAP provides a sustainable alternative for pavement construction.
