“…Mohammed et al [ 96 ] concluded that modifying the binder with 12 mm long glass fibers at a proportion of 1% by bitumen volume led to better performance than the unmodified bitumen and modified bitumen with cellulose fibers in terms of cracking and rutting resistance. Fu et al [ 97 ] evaluated an amended asphalt mix with glass fiber at the optimum content of 0.5% by mix weight. The outputs of the study emphasized that adding glass fiber enhanced the tensile strength and cracking resistance 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 advantage of 12 mm BFs in improving the ductility of asphalt mixes was more obvious. Fu et al [ 28 ] utilized the acoustic emission technique to investigate the failure load of BF asphalt mixes splitting at −10 °C. The addition of BFs increased the breaking load of the mix by 38.8%.…”

This paper conducts a thorough review of the literature on the feasibility and current state-of-the-art incorporation of basalt fiber (BF) into asphalt pavement materials, focusing on fiber characteristics, dosage, incorporation methods, mixture properties, and surface modification techniques. The optimum basalt fiber dosage should be determined based on engineering performance parameters such as asphalt type, fatigue cracking, thermal cracking, rutting, and moisture resistance of asphalt mixtures. Basalt fibers are added to asphalt mixes by dry method or mixed method to achieve better dispersion. Adding BF to asphalt mixtures increased performance characteristics like cracking resistance, rutting resistance, and fatigue resistance. Overall, incorporating BF into asphalt mixtures would lower costs while increasing pavement service life. More research is needed to fully understand the effects of different sizes of BF on pavement performance and the possible environmental and economic repercussions of fiber surface alteration.

“…Türkiye'de de Karayolları Genel Müdürlüğü tarafından aşınma, binder ve bitümlü temel tabakalarında kullanılacak agregalara ait dane büyüklüğü dağılımı, alt ve üst limitlere sahip olan gradasyon zarfı olarak belirlenmiştir [10]. Gerek yurtiçi gerekse yurtdışı çalışmalarda, araştırmacıların gradasyon zarflarındaki orta hattı yani ortalama gradasyon değerlerini tercih ettikleri görülmektedir [2,[11][12][13][14][15][16]. Agrega, bitüm ve karışımla ilgili diğer özellikler aynı kalsa dahi, agrega gradasyonu olarak zarftaki ortalama değerlerden farklı gradasyon kullanılması ile karışım özelliklerinin değişim göstereceği açıktır.…”

Gradation properties of the bituminous mixture in Turkey, according to the layer to be used, are specified in the Highway Technical Specification. In this study, it was aimed to investigate the effects of five different aggregate gradations created as lower, middle and upper limits as well as by offsetting the lower and upper limits of the Type-1 gradation envelope defined for wearing course in the specification on the mechanical properties of bituminous mixtures. With the determined five gradations, both the effect of variations in the gradation envelope and the expansion potential of the gradation envelope were investigated. For this purpose, Marshall designs were applied on the bituminous mixtures created with different aggregate gradations. According to the test results, optimum bitumen requirement of the mixture increased as the aggregate gradation got thinner. It has been determined that as the gradation gets thinner, the void filled with bitumen ratio (Vf) and the percentage of voids in mineral aggregate (VMA) increase, while the unit weight (Dp) decreases at the optimum bitumen ratio. At the same time, it was observed that the gradation envelope defined for Type-1 may have an expansion potential.
