“…A Joint Performance Score (JPS) value for each alternative is determined from the response variables employing the WASPAS method with the help of Equation (4) through Equation (9). First, the normalized decision matrix for beneficial and non-beneficial criteria is obtained by using Equations (5) and (6), as shown in Table 10. Subsequently, by using Equations (7) and (8), the weighted normalized sum model and weighted normalized product model were calculated as can be observed in Tables 11 and 12, respectively.…”

“…However, despite the advantages previously mentioned, the service life of the PA mixture is significantly shorter (i.e., 10-12 years) in comparison to dense-graded asphalt mixtures (i.e., 18 years) [5]. The high air void content of the mix means that the asphalt binder is more exposed to weather conditions; therefore, it is more likely to oxidize, causing a loss of adhesion in the aggregate-mortar matrix and loss of cohesion inside the asphalt mortar bridges, resulting in a reduction of raveling resistance [6][7][8][9].…”

Porous asphalt is a type of mixture characterized by having high air void percentages that offers multiple benefits when used in wearing courses in terms of driving safety, water flow management, and noise reduction. However, the durability of porous asphalt (PA) mixtures is significantly shorter when compared to dense-graded asphalt mixtures. This study investigated the impact of polyolefin–aramid fibers and hydrated lime in the functional and mechanical performance of porous asphalt mixtures. A parametric study based on the concept of design of experiments was carried out through the Taguchi methodology. Accordingly, an experimental design was conducted based on the L18 full factorial orthogonal array. Three control factors—fiber content, binder content, and filler type—were included at various levels, and multiple responses including total air voids, interconnected air voids, particle loss in dry conditions, particle loss in wet conditions, and binder drainage were assessed experimentally. Signal-to-noise ratios were calculated to determine the optimal solution levels for each control factor for the multiple responses. In the second phase of the research, multi-criteria decision-making techniques—namely, criteria importance through inter-criteria correlation and weighted aggregated sum product assessment—were used to transform the multiple-response optimization problem into a single-unique optimization problem and to elaborate a preference ranking among all the mixture designs. The most significant levels for acquiring the optimum overall response value were found to be 0.05% for fiber content and 5.00% for binder content and mixed filler with hydrated lime.

“…In the 2000s, the need to implement PPSs led researchers to search for ways to improve the quality of permeable pavements by incorporating various additives [22,23]. Additives like nanosilica were shown to improve the abrasion resistance of the PAM considerably [24]. Natural fibers such as cellulose fibers are among the most commonly used fibers in PAMs as they improve the binder stability [2,25,26,27,28,29,30,31].…”

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.

“…Pavement damage such as cracking, rutting, and stripping may be caused, in part, by the presence of a significant number of air voids [3,4]. Fiber is one of the additions that may enhance the performance of a pavement, and it is extensively used as a reinforcing agent in bituminous mixes [5,6]. Fiber is one of the additives that can increase the performance of a pavement.…”

Porous asphalt composition is frequently used for the surface extraction layer of pavements because to its open structure and high air void percentage, which lessens disturbance and offers protection during precipitation. Porous asphalt composition has a high air void percentage. This would make it possible for water to be stored horizontally inside the pavement layer as well as moved about within that layer. It is possible that this may lessen the impacts of splash and spray, hence improving drivers’ sight during rainstorms. On the other hand, because to the large percentage of air voids contained inside it, the porous asphalt would be prone to rutting, cracking, and peeling. The goal of this research is to explore the microstructure of porous asphalt that has been mixed with steel fibers in proportions ranging from 0 percent to 0.3 percent. The second objective was to analyze the long-term deformation of porous asphalt that had either 0 or 0.3 percent steel fiber content. In this study, a porous asphalt composition was developed with the help of Marshall mix design. Using sieve analysis, the whole mixture of coarse, fine, filler, bituminous binder, and a range of aggregate sizes was separated into its component parts. Pictures taken using a scanning electron microscope (SEM), an energy dispersive x-ray (EDX), an x-ray diffractometer (XRD), and a fourier transform infrared spectrometer (FTIR) are being used in this inquiry (FTIR). The findings point to the possibility that the performance of porous asphalt mixture might be greatly improved by the addition of steel fiber. Additionally, one may make the case that steel fiber has a longer lifespan than the several other forms of fiber that are used in porous asphalt pavement.
