“…Norhidayah et al [ 164 ] concluded that introducing 0.3% coconut fibers by mix weight into a porous asphalt mix composed of coconut shells as coarse aggregates reduced the drainage of the mix. In another study conducted by Haryati et al [ 165 ], the potential integration of 10% coconut shell and 0.3% coconut fibers in a porous asphalt mix was assessed. The study findings demonstrated that the addition of coconut shells and fibers notably boosted the rutting resistance and stability of the asphalt mix.…”

The utilization of synthetic, natural, and waste fibers in asphalt mixtures is constantly increasing due to the capability of fibers to improve the mechanical performance of asphalt mixes. The combination of fibers in asphalt mixes contributes to ecological sustainability and cost benefits. The objective of this paper is to introduce a citation-based review on the incorporation of synthetic, natural, and waste fibers in bitumen, dense-graded asphalt mix, stone mastic asphalt, and porous asphalt mix. Additionally, this article aims to identify research gaps and provide recommendations for further work. The outputs of this article demonstrated that there has recently been a growing interest in the use of natural and waste fibers in asphalt mixtures. However, more future studies are needed to investigate the performance of fiber-modified stone mastic asphalt and porous asphalt mix in terms of resistance to aging and low-temperature cracking. Furthermore, the period of natural fibers' biodegradability in asphalt mixtures should be investigated.

“…The tests were performed on the same equipment to obtain the resilient modulus. The test conditions were a haversine loading wave, a frequency of 1 Hz, and a temperature of 25 • C. Four tension levels (20,25,30, and 35% of tensile strength) were applied, and three samples were tested at each level. The fatigue curve is represented by Equation (9).…”

“…The porous mixture's durability enhancement and fatigue resistance improvements can be achieved using modified asphalts [23]. Some authors have confirmed the porous asphalt mixtures' mechanical performance improvements through the introduction of fibres [25][26][27] or fatty acid amides [28] and by using modified asphalts, such as epoxy [29], polyurethane [30], rubber from waste tires [31], and styrene butadiene styrene-SBS [32][33][34].…”

One alternative measure to minimise the stormwater runoff volume and its pollutants and reduce impervious areas is to use permeable pavement. However, due to weak mechanical performance under heavy-load traffic related to fatigue resistance, porous mixtures and permeable pavements have restricted applications, i.e., parking lots and low-traffic roads. This work aims to evaluate the fatigue resistance of a porous asphalt mixture produced with highly modified asphalt (HiMA) and its potential contribution to reducing stormwater runoff and pollutants. In order to estimate the capability of runoff pollutants and stormwater flood reduction, a case study was performed on an urban road. A permeable pavement was designed using the porous mixture as a surface layer. The mixture volumetric parameters and asphalt content were established using the Marshall method, considering the void content, interconnected voids, permeability, Cantabro test, and moisture damage test evaluation. The resilient modulus and fatigue resistance tests were performed on a diametral compression device. The mixture design resulted in an asphalt content of 5.1% and a void content of 21.5%. The resilient modulus was 2764 MPa, and the porous mixture obtained excellent fatigue performance, allowing its application in diverse traffic conditions. The porous mixture efficiency infiltration capacity was 90%, and some runoff pollutants could be reduced after being filtered by the pavement surface, contributing to minimizing environmental contamination. This work filled part of a gap in predicting porous mixtures’ fatigue performance, collaborating to popularise and expand its use for various purposes.

“…On one hand, Diatomite filler enhances the rutting resistance, moisture damage, resilient modulus, and indirect tensile strength, on the other, hydrated lime improved the cohesion and reduced particle loss. Haryati et al [ 14 ] added coconut shells to PA mixtures as substitutes to aggregates and fibers as additions. It was concluded that coconut shells and fibers improve stability and rutting resistance.…”

Recent studies have shown that fibers improve the performance of porous asphalt mixtures. In this study, the influence of four different fibers, (a) regular aramid fiber (RegAR), (b) aramid fiber with latex coating (ARLat), (c) aramid fiber with polyurethane coating (ARPoly), (d) aramid fiber of length 12 mm (AR12) was evaluated on abrasion resistance and toughness of the mixtures. The functional performance was estimated using permeability tests and the mechanical performance was evaluated using the Cantabro test and indirect tensile strength tests. The parameters such as fracture energy, post cracking energy, and toughness were obtained through stress-strain plots. Based on the analysis of results, it was concluded that the addition of ARLat fibers enhanced the abrasion resistance of the mixtures. In terms of ITS, ARPoly and RegAR have positively influenced mixtures under dry conditions. However, the mixtures with all aramid fibers were found to have adverse effects on the ITS under wet conditions and energy parameters of porous asphalt mixtures with the traditional percentages of bitumen in the mixture used in Spain (i.e., approximately 4.5%).
