“…Many different composite modified fibres such as bitumen-treated fibres, polymer-added fibres, and more recently rubberized fibres have been introduced and experienced to promote their further application. All of these fibres have a cellulose base because it is better at binder absorption compared to mineral fibres [3,4] and proven effectiveness in many experimental studies and field practices [5]. In the literature, most of the studies were carried out on the possible alternatives for the commonly used cellulose fibres considering the economical and eco-friendly principles.…”

“…A waterproof layer with good surface drainage is formed with only 4% air voids and a high level of macro texture when the material is laid down. Due to their flexibility, asphalt mixtures can resist permanent deformation caused by heavy vehicle traffic without compromising pavement performance [11,27,29,33,43,44]. Fatigue cracking and rutting along the wheel tracks of pavements are caused by traffic loads that are repeatedly applied.…”

“…In addition, the mineral filler is more abundant in SMA than dense-graded mixtures, which have a higher percentage of coarse aggregate. SMA is resistant to permanent deformation and is capable of providing long-term behavior and strength [6,27,28], high resistance to reflective cracking and low noise pollution [24]. Asphalt binder, mineral filler, fine aggregate, and stabilizing additive typically make up the mortar.…”

All over the world, highway traffic is increasing rapidly, as is the population and the road network. The country's maximum and minimum temperatures also vary greatly. Moreover, the pavements are subjected to various types of damage. Pavement binders and mixtures are a constant area of research and development for scientists and engineers. Adding fibers to bituminous mixes may improve the properties of fatigue and strength of the material. Natural fibers may be used to improve asphalt mixtures performance due to their inherent compatibility with asphalt cement and excellent mechanical properties. Also, the high stone content and relatively high asphalt content in SMA mixture led to the occurrence of drain-down of the asphalt mastic from the mixture, and this problem requires the use of stabilizing additives such as cellulose fibers, mineral fibers, or polymers to mitigate this problem and ensure long-term performance. The most public sort of stabilizing additives is cellulose fiber. Overall, natural fibers in stone mastic asphalt mixes are discussed in this paper. An additional focus is on how asphalt concrete will be affected by natural fibers, mixing techniques, and managerial decisions. According to the review, the stabilizing and strengthening impact of natural fibers on the performance of asphalt mixes have been extensively researched. Natural fibers can significantly increase the rut and flow resistance of asphalt mixtures. Adding natural fibers to pavement can increase structural resistance to pavement distress.

“…A way to improve the performance of mixture is adding different materials [9][10][11], for example different kinds of fibres [12][13][14][15][16]. The most commonly fibres employed in asphalt mixture are the cellulose fibres in stone mastic asphalt (SMA) and porous asphalts to attain a higher asphalt content without it draining down during the mixing and placement process [17,18]. However, fibres can have other functions like controlling the cracking process and improves the toughness, residual stress capacity and tensile strength.…”

The addition of fibres to reinforce asphalt mixtures is a prospective field for pavement engineering, where the use of glass or synthetic macrofibers could potentially help not only as reinforcement for new asphalt mixtures, but also as part of asphalt overlays applied on deteriorated pavements to diminish reflective cracking during maintenance operations.In recent studies, it has been found that the addition of macrofibres can improve the rutting and fracture resistance of asphalt mixtures. However, the response of these mixtures to fatigue has not been studied yet. In this study, a complete performance characterization of a gap graded asphalt mixture with the addition of glass and synthetic macrofibres was studied. Also, a reference asphalt mixture without macrofibres was provided for comparison. Results showed that the addition of macrofibres improves water sensibility, rutting performance and stiffness of the gap grade asphalt mixtures studied. Also, it was observed during the fatigue tests that the incorporation of both types of macrofibres greatly improved the durability of the mixtures to fatigue cracking at medium range temperatures. This improved fatigue behaviour correlates to an extended useful life for the fibre reinforced asphalt mixtures. The synthetic macrofibres showed better fatigue behaviour at lower temperatures, while glass macrofibres gave a better response at the higher temperature studied.
