Abstract

Soil stabilization is the process of improving the engineering properties of soil and thus making it more stable. It is required when the soil available soil for construction is not suitable for the intended purpose.. It can be done by the use of controlled compaction, proportioning and the addition of suitable different types of admixtures and stabilizers. Soil stabilization is very necessary for various construction works like road pavement and foundation because it improves the engineering properties of BC Soil. The objective of this work is to estimate the effect of lime and Eggshell powder on some geotechnical properties of black cotton soil, in order to determine the suitability of lime and Eggshell powder for use as a modifier or stabilizer in the treatment of black cotton soil for roadwork. This work represents a study of the lime and Eggshell powder as the admixtures or stabilizers in improving some engineering Properties of Black Cotton (BC) soils. This experimental program evaluates the effect of the lime and Eggshell powder on the some basic engineering properties of BC soil such as Unconfined compression test, Compaction, and California Bearing Ratio (CBR) of BC Soil. The study on effect of Eggshell powder (ESP) on the stabilizing potential of lime on expansive clay soil. Tests were carried out to determine the optimal percentage of lime- ESP combination; the optimal quantity of lime was gradually replaced with suitable amount of Eggshell powder. The lime stabilized and lime-ESP stabilized mixtures were subjected to engineering tests. The optimal percentage of lime-ESP combination was attained at a 5% ESP+ 5% lime, which served as a control. Results of the, California Bearing Ratio( CBR), and triaxial compression test indicated that lime stabilization 10% is better than the combination of 5% ESP + 5% lime.
