Abstract	The use of glass fibers in bituminous concrete has gained attention as an effective method for improving the performance and durability of flexible pavements. This study examines the impact of glass fibers with different aspect ratios (lengths: 8 mm, 16 mm, and 24 mm) on the mechanical behavior of asphalt mixtures. Key parameters evaluated include Marshall Stability, flow value, air voids, voids in mineral aggregate (VMA), and voids filled with bitumen (VFB). The bituminous mixes were prepared using a dry mixing technique, with glass fibers incorporated at varying proportions (2.5%, 5%, 7.5%, and 10%) As a partial replacement for bitumen by weight Marshall Stability testing was carried out to evaluate the influence of fiber inclusion on structural integrity, resistance to deformation (rutting), fatigue life, and moisture sensitivity. The results demonstrate that the addition of glass fibers enhances both the strength and durability of the bituminous mix, with the most favorable performance observed at a fiber content of 7.5%. Beyond this level, the improvements were marginal or declined slightly. The study also highlights the role of fiber aspect ratio in improving compaction and crack resistance, emphasizing its importance in mix optimization. Overall, the findings support the use of glass fibers as a sustainable modifier for extending the service life of asphalt pavements. Each sample undergoes a Marshall Stability test to assess stability, flow, and void characteristics. Additionally, the study evaluates the impact of fiber addition on rutting resistance, fatigue life, and moisture susceptibility of the asphalt mix. The results indicate that the optimal fiber content significantly improves the stability and durability of the mix, reducing susceptibility to deformation and enhancing load-bearing capacity. The study also explores the effects of fiber size and dosage on cracking resistance, demonstrating that properly optimized fiber incorporation enhances the overall performance of asphalt pavements. This research provides valuable insights into sustainable pavement design, advocating for the effective utilization of glass fibers in bituminous mixtures for improved road performance and longevity.
