“…The use of natural fibers in asphalt mixtures to improve the moisture damage resistance and rutting resistance has been proposed in many researches, such as fibers from banana trees [4], bamboo plants [5], cellulose [6], coconut [7,8], hemp [9], jute [10], kapok [11], peat [12,13], and sisal [14]. The capability of water absorption of each type of fiber is different.…”

Moisture is one of the critical failures affecting asphalt pavement. It has been recently found that moisture created by rainwater and undrained water deteriorate the bonding interface between asphalt mastic and aggregate. Using different mineral fillers can lead to different moisture resistance in the same mix design. Nowadays, waste natural materials allow agriculturists to receive more income by recycling in many industries. In this study, the researchers adopted bagasse and coconut peat grinding into very fine particle passing through the sieve number 200 (0.075 mm) to replace the mineral fillers. Although the indirect tensile strength (ITS) test is commonly used for evaluating the moisture damage resistance of hot-mix asphalt (HMA) in a laboratory, there are some shortcomings in using this test, such as costly, heavy and indirect equipment. Another potential test that is likely to be more advantageous than the ITS test for evaluating the moisture damage resistance is the pull-off tensile strength (POTS) test. However, it is typically measured on a concrete surface, and no results using an asphalt mixture have been reported. The objectives in this study were to investigate the effects of waste natural fillers in asphalt mixture on adhesive bonding caused by moisture, and to determine whether the POTS test is a potential method in measuring moisture damage resistance in a laboratory. Results showed that the tensile strength ratios (TSR) of asphalt mixture with bagasse and coconut peat fillers are approximately equivalent to those with mineral fillers. Results also showed that asphalt mixtures with bagasse and coconut peat fillers can effectively prevent the moisture damage resistance. In addition, with the preliminary result, it was found that the POTS test showed a very good R square (R2) for a relation of TSR with the ITS test. As a result, the POTS can be a valid tool of quantifying moisture damage resistance with better simulating to field behavior, lower cost of equipment, and light weight.

“…To reach a homogeneous distribution of peat fibers in the asphalt mix, mixing should be performed only by the second approach; with the first approach, this homogeneity cannot be reached (see Figure 16). This is remarkable, since, considering the type and length of fibers, it has been reported in the literature that dry mixing was supposed to be sufficient [4,9,15,26] or it was not mentioned at all how fibers were mixed in the asphalt mixes [5][6][7][8]11,16]. 20 variable-speed stirrer at speed of 300 rpm in hot bitumen at the temperature of 150 °C with specially designed steel blades before adding it to the hot aggregates mix (see Figure 15b).…”

In this study, the feasibility of a natural peat fiber and finely ground peat powder as a modifier for bitumen was investigated. Initially, the as-received peat material was characterized in detail: the material was ground to various degrees, separated into fiber and powder fractions, and the gradation of the powder fraction as well as the size of the fibers were determined. A possible solubility in bitumen, the moisture content, and the density of both fractions were evaluated, and a limited chemical characterization of the fibers was conducted. Secondly, the rheological behavior of the powder and the fibers when blended with bitumen was evaluated. Additionally, a limited asphalt study was conducted. The rheological data showed the stiffening effects of the powder fraction and the presence of a fiber network, which were obvious as a plateau modulus towards lower frequencies. The fiber network was strain-dependent and showed elastic effects. This was further confirmed by the multiple stress creep recovery (MSCRT) tests. These tests also indicated that the fibers should improve the rutting resistance, although it was not possible to confirm this in asphalt rutting tests. Asphalt drainage tests demonstrated that adding dry peat, whether this is ground or not, is effective in reducing the binder drainage. However, the data also revealed that the amount of added peat fibers and powder should be limited to avoid difficulties in the compaction of these asphalt mixes.

“…Por otro lado, está el uso de diversas fibras naturales. Dentro de este tipo se usó las fibras de bambú, que, a partir de este estudio se evaluó la mejora del desempeño con el diseño de dos tipos de mezcla, una patrón y una con adición de fibra, siendo sometidas a pruebas de seguimiento de ruedas y vigas de flexión de tres puntos, se demostró que se fortaleció la conducta de formación de surcos y de agrietamiento a baja temperatura (Sheng et al, 2019). Dentro de la misma categoría se hace presente el uso de fibras de yute que, a partir del estudio que indagó la conducta a baja temperatura del cemento asfáltico Warmmix (mezcla producida a 20-25°C menos que el cemento asfáltico típico) reforzado con estas fibras, se obtuvo resultados favorables respecto a la mejora de la resistencia a la tracción (Mansourian, Razmi, y Razavi, 2016).…”

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.
