“…Este cambio conduce a un ligero aumento en los parámetros volumétricos, una mayor resistencia a la fatiga representada por una mejora en la TSR, y una reducción significativa en el escurrimiento del asfalto. Estos resultados sugieren que las fibras de basalto pueden desempeñar un papel beneficioso en la estabilización de mezclas SMA, y ofrecer un rendimiento superior en comparación con las fibras de celulosa convencionales (Chen et al, 2023c).…”

“…Nanoattapulgite (ATP) [13] is a water-containing magnesium-rich silica-aluminate mineral in fiber or rod form, with a large specific surface area, strong adsorption capacity, and possesses a function similar to that of the lateral root. BF [14] is produced by melting and drawing basalt at high temperatures, with excellent mechanical properties and characteristics of the main root, which has good reinforcement to the asphalt and asphalt mixtures. The plant root system bionic idea is shown in Figure 1.…”

Nano-attapulgite (ATP) is a layered silicate mineral with abundant reserves, large specific surface area, and low cost. The unique structure of ATP has attracted wide attention in the field of adsorption. In this study, a preparation technology of ATP grafting basalt fiber (BF) was proposed by chemical grafting method based on the idea of plant root bionics. The optimal preparation process of ATP grafting BF was determined through the tests of asphalt absorption performance, thermal stability performance, and segregation dispersion performance. The mechanism of ATP grafting BF was analyzed by micro-morphology, functional group changes, and elemental composition. Finally, the adsorption performance of ATP grafting BF was investigated on the basis of adsorption kinetics model and molecular dynamics simulation. The study results indicated that ATP-BFHCl had better compatibility and wettability with asphalt. The quasi-second-order kinetic equation could better fit the adsorption process of ATP-BFHCl on asphaltene, which indicated that ATP-BFHCl adsorbed asphaltene with chemisorption or ion exchange. The diffusion coefficient and diffusion activation energy of the saturate and the aromatic were larger, indicating a smaller molecular weight and faster movement, and lightweight components of asphalt are more easily adsorbed on the surface of ATP. The diffusion activation energy of asphaltene is the smallest and the reaction is the easiest to take place, which indicates that it is the first to react during temperature increase. The research results can provide a theoretical basis and technical support for BF surface treatment technology.

“…The incorporation of fiber materials could improve the road performance of the asphalt mixture [1][2][3][4][5][6][7][8]. Stone Mastic Asphalt (SMA) is a typical gap-graded asphalt mixture, which is widely used because of its excellent high-temperature stability, lowtemperature crack resistance and water stability [9][10][11][12][13]. In order to solve the problem of asphalt drainage and fine material segregation in gap-graded asphalt mixtures, lignin fiber (LF) with a good asphalt absorption capacity was incorporated in an asphalt mixture [14].…”

A basalt fiber asphalt mixture could improve the road performance of pavements and prolong the service life. The oil/asphalt absorption capacity of basalt fiber affects the road performance of asphalt mixtures to a certain extent. However, using kerosene as the medium to measure the oil absorption rate of bundle fibers by the vibration method, as the Chinese specifications recommends, is unreasonable. Therefore, the aim of this paper is to study the effect of the basalt fiber morphology on the oil absorption rate and the oil/asphalt absorption test methods suitable for asphalt mixtures with different structures (dense-graded and gap-graded), and to also explore the appropriate method to determine the oil/asphalt absorption rate of fiber to kerosene and asphalt. The results showed that the filamentous basalt fiber (FBF) was easier to disperse uniformly in asphalt than the bundled basalt fiber (BBF), and the oil absorption capacity of the FBF could more accurately characterize the actual working state of the fiber in the asphalt mixture. For the gap-graded asphalt mixture, the appropriate method to measure the fiber oil absorption rate is the combination of the vibration and centrifugation methods, while the fiber asphalt absorption rate is measured by the vibration method. For the dense-graded asphalt mixture, the combination of the extrusion and centrifugation methods are more reasonable to determine the fiber oil absorption rate, while the extrusion method is suitable for determining the fiber asphalt absorption rate. The concept of an effective fiber oil absorption rate is proposed to characterize the ability of fiber to adsorb kerosene in asphalt mixtures with different structures. A temperature of 160 °C is recommended as the test temperature to determine the fiber asphalt absorption rate. Kerosene as the asphalt absorption test medium could not directly reflect the ability of fiber to adsorb asphalt.
