Experimental Insights into Rutting and Stripping Resistance of Sisal Fiber Reinforced Asphalt Layers

This review paper focuses on the major factors of deterioration, specifically rutting, stripping, and moisture effects, which are key factors affecting road pavements globally. Stressing the need to tackle these distresses, the study aims to improve the performance of asphaltic courses via advancing bio-based reinforcement materials, especially sisal fiber. The paper tries to analyze the mechanism of rutting in asphalt mixtures with a special reference to sisal fibers as an agent to increase resistance to permanent deformation. However, fiber reinforcement with the asphalt mixtures are also briefly described in the subject with the favorable effects of tensile strength, fatigue strength and crack propagation strength. The review further focuses on the ability of fiber reinforcement to enhance pavement service life, address pavement deterioration issues, and improving the service life of road pavements.
