Recent Advances in Basalt Fiber Reinforced Asphalt Mixture for Pavement Applications

Abstract

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.

Fiber-Reinforced Asphalt Mixture Design on Anti-Skid Surfacing for Field Testing High-Speed Vehicles on Pavements

“…Fiber has been used as a reinforcing material in road construction since the 20th century, and it can be classified as organic, metallic, mineral, glass, or synthetic (polyester, polypropylene, and aramid). In 1960, Davis from the University of Toronto conducted the first systematic study on asbestos fiber for road use [ 21 ]. After that, studies on asbestos-fiber-modified asphalt mixture continued to be carried out, while asbestos was banned due to its huge harm to the environment and great impact on human health.…”

“…In 1984, lignin fiber replaced asbestos fiber as the stabilizer in SMA mixtures, and thus lignin-fiber-modified asphalt mixture research was carried out. However, there are also certain limitations of using lignin fiber, such as its characteristic of easy water absorption, and that it easily decomposes coke, which pollutes asphalt [ 21 ]. The application of polymer fibers began in the 1980s with a patent by DuPont in the United States, which applied a specially formulated reinforcing fiber made of polyester material to an asphalt mixture.…”

“…The application of polymer fibers began in the 1980s with a patent by DuPont in the United States, which applied a specially formulated reinforcing fiber made of polyester material to an asphalt mixture. Additionally, the research of Freeman showed that polyester fiber could significantly improve the road performance of asphalt mixtures in 1989 [ 21 ]. Polyester fiber was added to the asphalt mixture after the surface, along with an anti-aging treatment that can enhance the bonding strength between the asphalt and aggregate to make the connection closer [ 22 ].…”

“…Fibers can be added to asphalt or directly to asphalt mixtures, and there are generally two methods of adding fibers to asphalt mixtures, including the dry method and the wet method [ 18 , 21 , 26 ]. The dry method is to mix the fiber and mineral evenly and then add asphalt to the mix to form an asphalt mixture.…”

“…Basalt fiber (BF), as a new, environmentally friendly mineral fiber [ 19 , 20 ], has been widely used in asphalt pavement due to its unique advantages: a wide working temperature range, excellent mechanical properties, chemical stability, anti-aging and thermal insulation properties, etc., [ 21 ]. In Celauro’s and Hui’s research [ 22 , 23 ], basalt-fiber-modified asphalt mixtures show a better high-temperature performance with reference to permanent deformation resistance when compared with the traditional mixture. Moreover, the chopped basalt fiber is combined with the asphalt well and distributed in a three-dimensional network structure in asphalt mixtures, which can reinforce the low-temperature performance of asphalt mixture significantly [ 24 , 25 , 26 ].…”
