Sugarcane Bagasse Fibers for Enhancing Moisture Susceptibility Properties in Stone Mastic Asphalt

Stone mastic asphalt (SMA) mix amended with sugarcane bagasse fibers (SBFs) as a stabilizer was investigated experimentally in the present study. The SBF content combination varied (0, 0.15%, 0.30%, 0.45% and 0.60%) to produce different mixtures. prepared mixtures were then assessed for properties, such Marshall stability, tensile strength, draindown, which are crucial performance of flexible/bituminous pavements. experimental results revealed enhanced stability flow value, greater filling voids bitumen, reduced air SMA SBF. In addition, improvement strength observed. An increase ratio also susceptibility entry moisture into pores by performing draindown test, that exhibited due presence Therefore, it inferred inclusion beneficial enhancing achieving higher resistance penetration. study demonstrated use an active ingredient would result improved flexible pavements while reducing waste burden landfills aiding effective management.
