This thesis develops a novel constitutive model for unsaturated compacted soils, incorporating the traditional compaction curves. Dubbed as generalised MPK model, it couples hydraulic and mechanical behaviour incorporating environmental stabilisation concepts and strain accumulation upon wet-dry cycles. The model was validated by reproducing a range of phenomenological observations for isotropic and triaxial stress states both qualitatively and quantitatively.
