Abstract Lime is flexible hydraulics which has the property to improve the soil mechanics characteristics. For the muddy and argillaceous grounds, the traditional interaction between lime and their minerals is noticed immediately. The ground becomes friable and is drained, especially with the quicklime; the mixtu re can be stored for one short period (a few weeks) without its intrinsic properties not changing. For a good soil stabilization with lime it is necessary to lay out of certain relative data to the soil mechanics properties, like plasticity, granulometry a nd the water content to evaluate the possibilities for improvement. This work consists at the presentation of the results of a laboratory study on the treatment of a clay soil in the area of the Inhabitant of Algiers by incorporation of various contents extinct lime. For that, physical and mechanical tests such as (unconfined compression test, classification tests of the grounds in 1st place and shear test) were carried out and the results obtained highlight an unquestionable and definitely better improvement of the characteristics geotechnics such as the resistance of compression, resistance of shearing (angle of friction and cohesion)
