| In order to promote in-depth research on biomass materials in road applications, this paper comprehensively reviews the research and application of pavement biomass materials on. Classifying pavement biomass materials into three categories-bio-oil, bio-fiber, and bio-filler-based on different application forms, weconducted a comprehensive analysis and summary of the performance of thesematerials. The analysis results indicate that the low-temperature performance of asphalt modifiedwith general bio-oil is effectively enhanced. To further improve it, consideration could be given to the addition of styrene-butadiene-styrene (SBS) or other compatible biological components for composite modification. For the bio-asphalt mixture, there is a general improvement in low-temperature crack resistance and fatigue resistance, although there may be a trade-off with reduced high-temperature stability and moisture resistance. As a rejuvenator, bio-oil can restore the high-temperature performance of aged asphalt and enhance its low-temperature properties. The addition of bio-fibers significantly improves the stability of asphalt and the high-temperature stability, low-temperature crack resistance, and moisture resistance of the mixture. Most bio-fillers can enhance the stability of asphalt and the fatigue resistance of asphalt mixtures. In conclusion, biomass materials are widely used on pavement, showing the potential to reduce dependence on petroleum products and possessing significant developmental prospects. Future research can focus on the following aspects: establishing a unified system for the joint preparation of biomass materials and bio-asphalt, enhancing standardization; strengthening microscopic research to expedite the identification and extraction of effective components in bio-oil; intensifying research in the field of bio-oil regeneration, specifically in resisting secondary aging; exploring more effective compound formulations. |
