“…A proper amount of binder is required in order to coat properly the fibers. According to scientific literature, a maximum value of 20% on 𝑃𝑃𝑎𝑎 𝑑𝑑𝑑𝑑𝑑𝑑 response is considered admissible [10,21]. Under the action of water, the particle loss of PA mixtures were higher as expected.…”

“…The determination of air voids percentage is based on the on the permeability performance of OGFC. Fibers are commonly added to OGFC mixtures to increase durability; however, this has an impact on the interconnection of the air void distribution and permeability performance [10]. Anik Gupta et al [11] investigated the impact of different aramid fibers on the permeability and the study results showed slight permeability decreases, which might be due to fibers blocking some of the air voids in the mixes.…”

This research evaluated permeability and hydraulic conductivity of Open Graded Friction Course (OGFC) in multiple directions. Using Computational Fluid Dynamics (CFD), Ansys Fluent was utilized to simulate the laminar flow model for twelve cubic specimens of OGFC with different geometry and various porosities. Reynolds number (Re ), permeability (K), and hydraulic conductivity (k) were computed for each simulation horizontally and vertically. According to the study, the horizontal permeability measurements were greater than the vertical measurements. Moreover, the permeability of OGFC is governed by the percentage of the air voids, aggregate particle size, and the thickness of the specimens. As the diameter and percentage of air voids increased, the permeability increased. Specimens with large size of aggregates and larger thicknesses have the highest values of permeability, while specimens with the small size of aggregates have the lowest values of permeability. In addition, the velocity of the flow inside the voids decreased as the diameter and percentage of air voids increased, while the pressure increased, according to the study.

“…Many investigations have reported advances in behaviour of Fibre Reinforced Asphalt Concretes (FRAC) [3,[19][20][21][22][23][24][25][26][27][28][29][30][31]. However, all mentioned works refer to short fibres (length \ 25 mm, less than the maximum size of the aggregate).…”

Fatigue behaviour of macrofiber reinforced gap graded asphalt mixtures

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.
