Study on the Reuse of Biochar as a Supplement of Stone Dust in Asphalt Mix

This study investigates the feasibility of using biochar as a partial replacement for stone dust in asphalt mixtures.Stone dust, a traditional filler material, is supplemented by biochar, a byproduct of biomass pyrolysis, to assess its mechanical and environmental benefits.The incorporation of biochar into asphalt mixtures is explored to improve performance and reduce costs.Key laboratory tests such as FTIR, XRD, Marshall Stability, Rotational Viscometer, and Wheel Tracking are conducted to evaluate the mechanical properties and durability of biochar-modified asphalt.The results indicate that biochar enhances the mechanical properties of the asphalt mix, leading to improved stability and durability.Additionally, the use of biochar offers environmental benefits, contributing to sustainable waste management by repurposing biomass byproducts.The study suggests that incorporating biochar in asphalt not only improves performance but also aligns with cost-effective and environmentally sustainable construction practices.
