“…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]. It was mentioned by Kumar et al [15] that natural fibers tend to mix thoroughly with dry heated aggregates.…”

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.

“…Se debe realizar una investigación detallada sobre los mecanismos de refuerzo similares de las fibras y cáscaras de cocos, así pues lo manifiestan Lay Ting, T., Putra Jaya, R., Abdul Hassan, N., Yaacob, H., & Sri Jayanti, D. (2015), indican además que las diversas propiedades de estos componentes del coco deben centrarse en el pavimento asfáltico investigaciones futuras, entonces por lo expuesto la presente investigación si podría ser aplicable en el Perú salvo con los ajustes de los porcentajes sobre todo de la fibra de coco y además considerando que el proceso de mezcla cumplan los requerimientos exigidos por el MTC y la normas ASTM.…”

“…176-190 -ISSN: 2313-1926 por lo que los agregados se recubrirán con una película más gruesa. En ese sentido también Lay Ting, T., Putra Jaya, R., Abdul Hassan, N., Yaacob, H., & Sri Jayanti, D. (2015) indican que esto puede reducir la oxidación de las mezclas asfálticas, la penetración y separación de la humedad, sin embargo para Al-Hadidy, A., & Yi-Qiu, T. (2009) todas las aplicaciones de asfalto tienen un problema, se volverá quebradizo a bajas temperaturas y blando a altas temperaturas, en ese sentido puede ser conveniente el uso de la cáscara y la fibra de coco pudiendo aumentar el rango de temperatura del asfalto y así cumplir con las exigencias técnicas de una mezcla asfáltica en caliente y además esta función puede reducir el secado y el agrietamiento que se producen en el pavimento asfáltico convencional cuando se enfrenta sobre todo a diversos climas a lo largo y ancho de nuestro país.…”

Las nuevas tecnologías en la producción de mezclas asfálticas se han visto influenciadas por la utilización de materiales amigables con el medio ambiente tales como polímeros, aceites y fibras naturales siendo en esta investigación el material estudiado el coco, que es un material que se presenta en la mayoría de regiones del Perú, además se facilita su uso, transporte y pues algunos estudios han demostraron que la cáscara de coco puede mejorar la resistencia a la tracción indirecta y el comportamiento de fluencia estática del asfalto, mientras que la fibra de coco puede aumentar la estabilidad, la resistencia al deslizamiento y el módulo de elasticidad. El objetivo de la investigación correspondió a determinar la influencia de la cáscara y fibra de coco en la mezcla asfáltica en caliente, para la cual se estudiaron previamente las características de la cáscara y la fibra para aplicarlos al asfalto como componentes en porcentaje dentro de una mezcla asfáltica en caliente, luego fue necesario evaluar los resultados según la normatividad peruana y la ASTM, finalmente se desarrollo el método Marshall para obtener el porcentaje óptimo de asfalto contrastando dichos rangos con una mezcla asfáltica convencional para de esa manera validar los resultados. Las conclusiones muestran que la cáscara y la fibra de coco si mejoran las propiedades de las mezclas asfálticas en caliente cuando se combinan con un asfalto, sin embargo no se descarta su aplicación en otro tipo de mezclas.

Environmental pollution caused by abundant wastes from agricultural activities has increased in recent years because of increased productivity. Agricultural waste recycling has been employed to solve this problem. Coconut shell charcoal (CSC) ash is a by-product of coconut shell (CS) used as a bitumen modifier to enhance the properties of the binder. This study investigated the effect of fineness charcoal ash from CS on the rheological properties of bitumen. Penetration, softening point, and viscosity tests were performed to determine the properties of the binder. Laboratory simulation of aging called rolling thin film oven test was applied in this study. CSC at different sizes (< 75μm, 75–150μm, and 150–300μm) was added to replace bitumen 60/70 PEN at 0%, 10%, 15%, and 20% by weight of the binder, respectively. Result showed that the bitumen became more viscous and that the softening point of bitumen increased, whereas the rate of penetration decreased when CSC was incorporated. CSC at a proper amount improved the resistance of bitumen to temperature susceptibility. In addition, the modification of bitumen can relieve the effect of aging. Modified bitumen shows better result when incorporated with the finest particle (< 75μm) of CSC compared with other sizes.
