“…ere is a large number of fiber-modified asphalt binders and fibermodified asphalt mixtures that can be used to deal with major flexible pavement problems such as rutting, fatigue cracking, thermal cracking, and loosening [11]. Furthermore, some drainage problems are investigated in porous mixture and the results show that polyester fiber incorporation reduces drainage problems [12,13].…”

With the rapid development of asphalt pavement, the drainage capacity of asphalt pavement is becoming more and more demanding. Therefore, it is imperative to study the permeable asphalt mixture. The air voids and the connected air voids are the main factors affecting the drainage function and low-temperature performance of asphalt pavement. In order to solve the drainage and low-temperature cracking problem, it is proposed to incorporate a certain amount of polyester fiber into the permeable asphalt mixture. This paper studies the air voids and low-temperature performance of asphalt mixture with different polyester fiber contents. It is concluded that with the increase of polyester fiber content, both the air voids and the connected air voids decrease first and then increase and reach the minimum value when the polyester fiber content is 0.4%. At this time, the low-temperature crack resistance of the permeable polyester fiber asphalt mixture is also the best.

“…Moreover, fibers act as a barrier inside the mix, preventing the formation and propagation of cracks [18]. In PA mixtures, it is well known that fibers are good stabilizers preventing binder leakage and so favoring the increase in binder content [19].…”

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.

“…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]. For low-temperature crack resistance, glass fibers can be used [32].…”

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.
