“…However, most of the studies are focused on the macro-performance. Due to the complexity of the types of fiber used in different studies [16,17,18,19,20,21], it is difficult to find some generalized conclusions. At the same time, research on the mechanism of fiber-reinforced asphalt is relatively limited, and there are still many problems to be solved.…”

This paper presents an experimental study about the influence of interfacial properties on the performance of fiber-reinforced asphalt. In this study, four types of fiber including one fiber-reinforced plastic (FRP), two lignin fibers, and one basalt fiber are used, and also four types of asphalt: Asphalt No. 90, asphalt No. 70, one styrene-butadiene-styrene (SBS) modified asphalt, and asphalt rubber are used. The surface energy parameters of various asphalts and fibers and the shear strength of various fiber-reinforced asphalts are measured. On the basis of these measurements, the influences of surface properties of asphalt and fiber on the performance of fiber-reinforced asphalt are analyzed. The results show that the shear strength of asphalt binder can be significantly increased by adding fibers, and the reinforcement effect is closely related to the types of asphalt and fiber. It was discovered, for the same asphalt, that the basalt fiber has the best reinforcement effect, followed by the two lignin fibers, and the FRP. For the same fiber, asphalt rubber was the most reinforced, followed by the SBS modified asphalt, asphalt No. 70 and asphalt No. 90. It was also discovered, for the same asphalt, the higher the surface energy of the fiber, the better the fiber reinforcement effect. The analysis indicates a good correlation between the work of adhesion between asphalt and fiber and the effect of fiber reinforcement. The results can be used as a basis for the selection of the proper fiber-asphalt combination to improve fiber reinforcement effects.

“…Kassem y colaboradores afirmaron que son muchas las fibras sintéticas utilizadas en las mezclas asfálticas, dentro de los diferentes tipos utilizados, las fibras de aramida y poliolefina tienen un efecto positivo sobre el desempeño de la mezcla asfáltica cuando se usan en las mezclas con un tamaño de agregado máximo nominal grande (Kassem, Saleh, Zalghout, y Chehab, 2018). Además, Bueno y Poulikakos (2020) estudiaron no solo el uso de fibras de aramida y poliolefinas (tipo A), sino también de fibras de poliacrilonitrilo (tipo B), demostrando la idoneidad de su uso en las mezclas asfálticas, al mostrar efectos positivos superiores al de una mezcla ordinaria.…”

La demanda del uso de pavimentos flexibles va creciendo raudamente debido a su buen desempeño, pero este está siendo afectado de manera considerable debido al aumento del tráfico y las variaciones climáticas, esto trae consigo la presencia de fallas considerables en el pavimento, causando que su desempeño disminuya y, por ende, se acorte su tiempo de vida útil. Este documento tiene como objetivo realizar una revisión sistemática de los distintos tipos de fibras usados en las mezclas asfálticas para la mejora de sus propiedades mecánicas, además de estudiar los porcentajes y longitudes óptimas, las pruebas utilizadas, el desempeño de las mezclas según el tipo de betún, el tipo de mezcla asfáltica y, finalmente, se revisa la rentabilidad que proporciona el uso de fibras en las mezclas asfálticas. Se revisaron 81 artículos publicados en las bases de datos de Scopus y Ebsco, entre los años 2014 al 2021, los cuales tuvieron el mismo objetivo de estudiar las características mecánicas de las mezclas asfálticas con adición de fibras. Se concluyó que las fibras, además de mejorar las propiedades de los pavimentos flexibles, son rentablemente buenas ya que, a pesar de tener un aumento en el costo inicial, demuestran un incremento en el ciclo de vida, siendo así económicamente factibles para proyectos viales que se realicen con el uso mezclas asfálticas, además se recomendó proseguir con estudios encaminados a utilizar este tipo de mezclas asfálticas.

“…The influence of addition of polyolefin and aramid fiber depends on the type of the binder, as the effectiveness of fibers is higher on the unmodified binder than on the SBS-modified binder [100]. Chen et al [21] studied the working mechanism of mineral, cellulose, and polyester fibers in asphalt mixtures and pointed out that, due to higher interfacial area in the case of mineral fibers, mineral fibers with lower diameter have greater toughness than the polyester fibers of higher diameter.…”

Incorporation of Additives and Fibers in Porous Asphalt Mixtures: A Review

Despite the numerous benefits for preserving the hydrological cycle, permeable pavement systems (PPSs) found their major application in parking spots and for light traffic scenarios due to their limited durability and strength. To make the PPSs suitable for heavy traffic conditions without significant distresses, research is shifting toward the adoption of novel binders and additives for designing multifunctional porous asphalt mixtures which make up the surface course of PPSs. Certain additives are well known for enhancing the durability of dense graded asphalt mixtures and improving fatigue and rutting resistance. However, the studies on the influence of additives on abrasion resistance and binder draindown, which are the common problems in porous asphalt mixtures (PAMs), are still not well established. This paper summarizes best practices performed on PAMs and recommends possible future research directions for its improvement. Particular emphasis is placed on strength and resilience of PAMs by incorporating additives like nanosilica, crumb rubber, warm-mix additives, fibers (such as cellulose, glass, steel, and synthetic fibers), and some eco-friendly materials. It was found that different additives seem to have different effects on the properties of PAMs. Moreover, the combination of additives has synergistic benefits for the performance of PAMs, especially in urban pavements.
