Performance evaluation of structural properties for soil stabilised using rice husk ash

The present study aims to stabilise local clayey soil with a varying percentage of rice husk ash (RHA). The RHA was collected from rice milling located near Roorkee city. As this material is abundantly available in the local area, efforts have been made to investigate the potential of the RHA–soil mixtures with respect to shrinkage limits, compaction characteristics, unconfined compressive strength (UCS), triaxial test, split tensile strength test and the California bearing ratio (CBR) after subjected to different humidity conditions, so as to utilise in road construction, if found suitable. The laboratory results indicate that admixing of RHA decrease the maximum dry density, but increased optimum moisture content with increase in RHA content. Inclusion of RHA not only improved CBR, UCS and split tensile strength of clayey soil but also, shown considerable improvement on cohesion and angle of internal friction too.
