CONCLUSION Expansive soils also called swelling soils are prone to volume changes corresponding to change in moisture content. Expansive soils have been reported from many parts of the World, mainly in the arid or semi-arid regions of the tropical and temperate zones like Africa, Australia, India, South America, United States and some regions in Canada. About one-fifth of the land area in India is covered by these soils. Because of the alternate Swelling and Shrinkage, lightly loaded structures such as foundations, pavements, canal linings and residential buildings founded on them are severely damaged. Design and construction of Civil Engineering structures on and with expansive soils is a challenging task for civil Engineers.
For countering the problems of expansive soils, different innovative techniques were suggested in the literature. Several investigations were carried out in India and Worldwide to stabilize expansive soils and normal(clay) soils like moorum soil using different additives like Cement, Lime, and asphalt emulsion.
The scope of the present investigation encompasses studying the Strength and Deformation characteristics of mechanically stabilized expansive soils using lime, cement and asphalt emulsion. All the test results are analysed to study the effect of stabilizing agents on moisture-dry density, strength and deformation characteristics of clay. Based on the results present in this investigation, the following conclusions are drawn.
Optimum moisture content of all soils increases by adding stabilizing agents like lime and cement. Dry density values decreases with increasing of lime and cement proportions up to certain limit and then again dry density values increasing. The shear parameters like angle of internal friction and cohesion values of soils increases with addition of lime cement and emulsion when compared to normal soils. CBR values of all soil samples increases soils with stabilizing agents when compared soils without stabilizing agents. For clay soil stabilization 6% lime is best suitable and it gives better results
For poorly graded soils 2% emulsion also gives better results
Lime, cement and emulsions are best suitable for stabilization of clay.
