The construction of road infrastructure relies heavily on petroleum-derived bitumen, resulting in significant greenhouse gas emissions and depletion of fossil fuel resources. Bio-bitumen has emerged as a sustainable alternative produced from renewable biomass sources such as lignin, agricultural residues, waste cooking oil, and algae. This study reviews the production methods, engineering properties, environmental benefits, challenges, and global applications of bio-bitumen. Various international case studies demonstrate the potential of bio-based binders in reducing carbon emissions while maintaining pavement performance. The findings indicate that bio-bitumen can partially replace conventional bitumen and contribute to sustainable pavement construction practices. Future research should focus on large-scale implementation, performance monitoring, and development of standardized production techniques.
