植物纤维增强沥青基道路材料研究进展OA

Asphalt pavements often deteriorate under traffic loads and environmental factors,which shortens their ser-vice life and jeopardizes road safety.Plant fibers,which are lightweight,high-strength,abundant,and low-cost,serve as sustainable reinforcements in asphalt mixtures.They improve mechanical performance while reducing cracking and aggregate displacement.This paper introduces the classification and physical properties of plant fibers,summarizes sur-face treatment methods to address their hydrophilicity and improve fiber-asphalt interfacial bonding,and reviews the rheological properties at high and low temperature,fatigue resistance of plant fiber-reinforced asphalt binders,as well as the preparation techniques and pavement performance of asphalt mixtures.Future research should integrate intelligent mix design optimization,multi-scale interfacial mechanism studies,and standardized engineering systems to synergisti-cally advance the high performance,functionalization,and green sustainable development of plant fiber-reinforced as-phalt pavement materials.
