Abstract: A series of consolidated undrained triaxial shear tests were performed on lime treated expansive soil samples experienced freezethaw cycles. The impact of freezethaw cycling on the shear strength parameters of treated soils has been studied. The relationship between the shear strength of the treated soils and the number of freeze thaw cycles is developed through the study. The failure mechanism of the lime treated expansive soil due to the freezethaw cycling is also presented in this paper.

Key words: lime treated expansive soil, freezethaw cycling, cohesion of soils, shear strength
