“…Moreover, the authors concluded that basalt showed the best performance. According to Kou et al [ 159 , 160 ], the appropriate contents of basalt fibers, polyester fibers, and lignin fibers as bitumen modifier are 2%, 3%, and 4% by bitumen weight, respectively. The authors confirmed that these contents remarkably enhanced performance in terms of permanent recovery and cracking resistance.…”

The utilization of synthetic, natural, and waste fibers in asphalt mixtures is constantly increasing due to the capability of fibers to improve the mechanical performance of asphalt mixes. The combination of fibers in asphalt mixes contributes to ecological sustainability and cost benefits. The objective of this paper is to introduce a citation-based review on the incorporation of synthetic, natural, and waste fibers in bitumen, dense-graded asphalt mix, stone mastic asphalt, and porous asphalt mix. Additionally, this article aims to identify research gaps and provide recommendations for further work. The outputs of this article demonstrated that there has recently been a growing interest in the use of natural and waste fibers in asphalt mixtures. However, more future studies are needed to investigate the performance of fiber-modified stone mastic asphalt and porous asphalt mix in terms of resistance to aging and low-temperature cracking. Furthermore, the period of natural fibers' biodegradability in asphalt mixtures should be investigated.

“…Figure 15(b) shows that no new functional groups or absorption peaks were generated in the asphalt binder after the addition of the fbers, indicating that the interaction between the straw fber and asphalt binder was primarily physical [32]. Similarly, the modifed straw fber asphalt binder showed no new absorption peaks, indicating the absence of a chemical reaction between the residual NaOH solution on the surface of the straw fber and the asphalt.…”

In this study, the correlation between the microstructure of straw fibers and the macroscopic properties of asphalt binders is investigated. Penetration, softening point, bending beam rheometer, and toughness tests are performed to investigate the relationship between the pavement properties of fiber asphalt binders and each of the fiber types and contents. Subsequently, a four-component test, SEM, Fourier transform infrared microscopy, and fluorescence microscope tests are performed to analyze the microstructure of the straw fiber and its effect on asphalt properties. The results show that the high-temperature performance and shear resistance of the asphalt binder were enhanced with an increase in the modified straw fiber content. The low-temperature performance and toughness of the asphalt binder were reduced because of excessive fiber, and the recommended fiber content is 1.5%–2.0%. The adsorption capacity of the modified straw fiber for the light components of asphalt increased by 5.4% on average, and the low-temperature creep capacity of asphalt decreased by 9.6%. The surface roughness of the straw fiber increased via modification, and the shear resistance, high-temperature deformation resistance, and stress relaxation ability of the asphalt increased by 23.1%, 6.5%, and 5.7%, respectively. The comprehensive properties of the asphalt binder with modified straw fiber are similar to those of lignin fiber.

“…The rheological properties of short-cut BFs (CBF), wool-like BFs, lignin fibers, and polyester fibers integrated with SBS modified asphalt were investigated by Kou et al [ 69 ]. Shape, tensile strength, elastic modulus, and content of fibers are critical elements in defining the rheological characteristics of asphalt mixture.…”

This paper conducts a thorough review of the literature on the feasibility and current state-of-the-art incorporation of basalt fiber (BF) into asphalt pavement materials, focusing on fiber characteristics, dosage, incorporation methods, mixture properties, and surface modification techniques. The optimum basalt fiber dosage should be determined based on engineering performance parameters such as asphalt type, fatigue cracking, thermal cracking, rutting, and moisture resistance of asphalt mixtures. Basalt fibers are added to asphalt mixes by dry method or mixed method to achieve better dispersion. Adding BF to asphalt mixtures increased performance characteristics like cracking resistance, rutting resistance, and fatigue resistance. Overall, incorporating BF into asphalt mixtures would lower costs while increasing pavement service life. More research is needed to fully understand the effects of different sizes of BF on pavement performance and the possible environmental and economic repercussions of fiber surface alteration.
