Volumetric constitutive behaviour of an unsaturated basaltic expansive clay stabilised using lime

This research project extended the understanding and developed a new model in relation to volumetric behaviour of a lime-stabilised unsaturated expansive clay by using net stress, void ratio, and moisture ratio, where suction was the dependent variable. The clay selected was a residual soil derived from a weathered quaternary basalt deposit located in Victoria, Australia. The new model has extended the current Monash Peradeniya Kodikara framework proposed by Kodikara (2012).
