Effect of freezing and thawing on strength and permeability of

In this study, the effect of freezing and thawing on the strength and permeability of two clayeysoils (high and low plasticity), which had been stabilized with lime, were investigated. before and afterstabilization, the permeability and strength of the specimens were determined with various freezethawcycles. results of this study indicated that for both clays, 6% lime addition increased the hydraulicconductivity of the specimens 1000 times. however, the hydraulic conductivity of clay with 6% limeincreased 1020 times after only 3 freeze-thaw cycles. the results of strength tests exhibited differenttrends. the strength of stabilized high plasticity clay increased approximately 15 times at the end of 28day curing, whereas the strength of stabilized low plasticity clay increased about 3 times only. the strengthof both stabilized clays decreased 1015% at the end of the freeze-thaw cycles.
