# Laboratory Evaluation and Finite Element Modeling of SBS and Basalt Fiber Modified Mixtures
## 1 Introduction
A dynamic shear rheometer and bending beam rheometer were employed to study the rheological properties of various mixture types. Results showed that basalt fiber 2% with 9 mm fiber size outperformed other mixture types, with temperature performance and low-temperature stress dissipating ability. [PERSON] et al. [5] evaluated the effects of basalt fibers on bitumen and asphalt mixtures using various percentages of basalt fiber. Different tests including viscosity, water stability and splitting tensile strength tests were performed on prepared specimens. Results showed an increased stiffness modulus of asphalt mixtures and increased deformation resistance at the recommended basalt fiber percentage of 0.3%. [PERSON] et al. [19] evaluated the low-temperature performance of basalt fiber-reinforced asphalt mixtures in terms of freezing and thawing cycles. Basalt fiber rubber composite was used for modifying the asphalt mixtures. Results showed further improvement in performance of the basalt fiber-reinforced asphalt mixtures in terms of freezing and thawing action by 0.3%. [PERSON] et al. [20] evaluated the high-temperature properties of bundled basalt fiber, lignin fiber and polyester fiber mixed with asphalt mixtures. Results showed increased fracture energy of the asphalt mixtures mixed with basalt fiber and increased high-temperature performance. [PERSON] et al. [21] evaluated the effect of adding basalt fiber to asphalt mixtures in terms of fatigue cracking, thermal cracking and rutting. Results showed increased cracking and rutting resistance of the asphalt mixtures when reinforced with basalt fiber. [PERSON] et al. [22] used basalt fiber asphalt concrete for the performance enhancement of asphalt mixtures measured using machine learning models including Gradient Boosting, Particle Swarm Eagle and Bald Eagle Search techniques. Results showed increased performance of the basalt fiber asphalt concrete in terms of Marshall stability, with the highest level of prediction exhibited by the Bald Eagle Search model. [PERSON] et al. [23] evaluated the impacts of adding basalt fiber on the viscosity, stability and splitting tensile strength of asphalt mixtures. Result showed an increased tensile strength and stiffness modulus of asphalt mixtures with a percentage of 0.3% basalt fiber. [PERSON] et al. [24] evaluated the effects of adding basalt fiber, lignin fiber and polyester fiber on the toughness,wear resistance and mechanical strength of asphalt mixtures. Results showed superior performance of asphalt mixtures with basalt fibers in terms of increased rutting and fatigue cracking resistance predicted by using the Random Forest model. [PERSON] et al. [25] evaluated the effects of adding basalt fiber to SBS-modified asphalt mixtures on aging, freezing and thawing, rutting and low-temperature bending of asphalt mixtures. Results showed increased high-temperature stability and low-temperature cracking resistance of asphalt mixtures with added basalt fiber. [PERSON] et al. [26] evaluated the effects of adding copped basalt fiber (CBF) on tensile strength, durability, fatigue damage and mechanical strength of asphalt mixtures. Mixtures were prepared with chopped basalt fiber percentages of 3% and 4%. Low-temperature cracking tests, freeze thaw tests and wheel tracking tests were used to evaluate the performance of different percentages and length variations of basalt fiber. Results showed an increased performance of basalt fiber with an optimum fiber length of 6 mm and fiber percentage of 3%. [PERSON] et al. [27] evaluated the effects of adding basalt fiber to asphalt mixtures in terms of the flexural tensile strength of asphalt mixtures. Results showed increased tensile strength and stiffness modulus of fiber-reinforced asphalt mixtures. [PERSON] et al. [28] evaluated the effects of basalt fiber on hot-in-place asphalt recycling mixtures. Recycled asphalt mixtures consisted of 70% Recycled Asphalt Pavement (RAP) and 30% new mixture.
