The increasing amount of sugarcane fibrous waste presents environmental problems. The reconstruction of existing highways due to modern globalization results in a larger volume of scarified pavement materials that are often discarded as waste. This study attempts to evaluate the geotechnical characteristics of reclaimed pavement materials that can be stabilized with sugarcane bagasse ash (SCBA). Finding an economical and sustainable way of reusing reclaimed pavement soils instead of using verging laterite soil for road construction could potentially unlock a new dimension. The preliminary results show that sugarcane bagasse ash can potentially improve the reclaimed soil’s strength characteristics, with an increased proportion of sugarcane bagasse ash, Unconfined Compressive Strength (UCS), and California Bearing Ratio (CBR) was found to increase by more than 350% and 100% respectively. The overall geotechnical characteristics are significantly improved by increasing the amount of sugarcane bagasse ash, which make reclaimed soil a potential suitor in relaying and repair maintenance of pavements.
