Abstract Flexible pavements are widely used for road construction because of their flexibility, ease of construction, and economical performance. However, conventional bituminous pavements may suffer from rutting, fatigue cracking, thermal cracking, and moisture-related deterioration under repeated traffic and environmental conditions. The present experimental study investigates the effect of incorporating glass fiber into bituminous concrete and evaluates its influence on the engineering properties of the pavement mix.
In the proposed experimental program, conventional bituminous concrete is compared with glass-fiber-reinforced bituminous concrete containing different percentages of glass fiber. The Marshall mix-design method is used to determine the optimum binder content and evaluate Marshall stability, flow, bulk density, air voids, voids in mineral aggregate, and voids filled with bitumen. Additional performance tests such as indirect tensile strength and moisture susceptibility may be conducted to assess the improvement in pavement performance.
Glass fibers act as reinforcing elements within the bituminous mixture. They can improve the internal tensile resistance and help distribute stresses within the pavement. Published experimental studies have reported improvements in Marshall stability and resistance to rutting and moisture-related damage at suitable fiber contents, although excessive fiber can cause agglomeration, poor workability, and reduced stability. One recent experimental study reported maximum Marshall stability at 0.5% glass fiber, while another study recommended 0.25% glass fiber for its investigated mix. These differences demonstrate that the optimum fiber percentage depends on the materials and mix design used.
