## 2 Literature Review
[22] have compared the performance of Basalt fiber, Lignin fiber and Polyester using Marshall stability tests, three point bending tests and wheel-tracking tests. Results showed increased performance of basalt fiber when compared to other fiber types in terms of low-temperature performance, Marshall stability, and Tensile strength ratio, using an optimum dosage of 0.3%. [PERSON] et al. [23] added basalt fiber with different contents of 0.25%, 0.35%, 4.9% and 5,2% to SBS-modified asphalt mixtures. Results showed increased high-temperature performance using the wheel-tracking tests when compared to SBS only modified mixture samples. [PERSON] et al. [24] have added the basalt fiber to different bitumen grades for performance evaluation of basalt fiber-reinforced asphalt mixtures. Results showed increased fracture resistance and a delay in the crack initiation of pavement structures. [PERSON] et al. [25] have evaluated the effect of adding basalt fiber on the fatigue life of asphalt mixtures. Fatigue damage for the basalt fiber-modified samples was calculated in the form of cumulative dissipative energy of the mixtures. Results showed good performance and increased fatigue life of asphalt mixtures with an addition of 0.3% basalt fiber. [PERSON] et al. [26] have added basalt fiber and diatomite for the fatigue performance improvement of asphalt mixtures for various penetration-grade bitumen types. Results showed enhanced improvement of asphalt mixtures with the addition of basalt fibers and diatomite. [PERSON] et al. [2] have evaluated the effect of basalt fibers on Marshall properties, dynamic stability, and deformation resistance of asphalt mixtures. Results showed increased permanent deformation resistance and decreased rutting of mixtures reinforced with basalt fiber. [PERSON] et al. [11] performed the dynamic shear rheometer testing of bitumen samples reinforced with basalt fiber and compared them against virgin binders. Results showed a higher complex modulus and a lower phase angle with a higher rutting factor when compared to the performance of virgin binders, thereby improving the high-temperature performance of asphalt mixtures. Glass fiber has been previously used for performance enhancement of asphalt mixtures. [PERSON] et al. [15] have used glass fibers to evaluate the long-term and short-term ageing of asphalt mixtures using indirect tensile strength, fracture energy, and moisture susceptibility tests. Result showed an increase in tensile strength, decreased susceptibility to moisture damage, and an increased resistance to rutting damage by using the glass fiber, but with an increase in costs for material procurement. [PERSON] et al. [27] have used the glass fiber for improving the performance of asphalt mixtures. Marshall stability and flow tests were conducted on glass fiber-reinforced samples. Results showed an increase in Marshall stability and a decreased flow value with an optimum percentage of glass fiber at 0.25%. [PERSON] et al. [28] have used glass fibers and different parts of recycled asphalt pavement for a performance enhancement of asphalt mixtures. The dosage of glass fiber used was 0.12% for improvement in crack resistance. Results showed increased cracking resistance of samples when tested under a semi-circular bending tests. [PERSON] et al. [29] have also performed rutting and moisture damage evaluation of glass fiber-modified asphalt mixtures for RAP mixtures. Results showed increased resistance to permanent deformation and moisture susceptibility of the asphalt mixtures with a higher percentage of RAP. However, in the current research, the comparison based on costs of procurement of materials, including basalt fiber, ceramic fiber, and glass fiber, has not been evaluated, and no direct comparison between these fiber types has been performed in terms of fatigue rutting damage. The current research also lacks the use of finite element modelling for a performance comparison of different fiber types used in terms of rutting and fatigue damage.
