| Abstract This paper is aimed to study some of the hydraulic properties (permeability and water retention) of a stabilized clayey soil selected from Mosul area. The optimum lime stabilization percentage was found to be 4 %. Cement amounts of 6 % and 18 % are needed to achieve a minimum unconfined compressive strength of 1400 and 5600 kParespectively “suggested limits for stabilized soil suitable as a base course”. For the same indicated range of strength, a combination of lime-cement ratios of 1-3 % and 2-9 % respectively were found to be sufficient to achieve this limit.Permeability of natural soil was found to increase with treatment of lime, cement and lime-cement. A maximum increasing in permeability about 17 fold was found using 4 % lime. While the permeability was 1.2 folds as a minimum increase when treating the soil with 18 % cement. The soil-water characteristics curve shows that (S-Shape) curves were maintained for natural and stabilized soil. | ||
