Abstract
AbstractExpansive soil always creates higher problems for lightly loaded structures than the moderate to heavy loaded structures by changing its volume along with the seasonal moisture variation and unequal settlement. As a result, damage to foundation systems, structural elements and architectural features defeats the purpose for which the structures are built. Geotechnical researchers are searching for various options to mitigate the adverse nature of the expansive soil. In the present study, an attempt is made to investigate the feasibility of mixing the fly ash and palm oil fuel ash to the expansive soil in order to reduce its plasticity characteristics to stabilize the expansive soil. Test results show that stabilizing with fly ash and palm oil fuel ash enhances the properties and the strength of the expansive soil as compared to untreated expansive soil.KeywordsExpansive soilFly ashPalm oil fuel ashStabilization
