Expansive soil is which possess poor shear strength with high swelling and shrinkage. The behavior of
the soil under the application of loads changing its physical and engineering properties. When the expansive soil is
exposed to variation in climatic condition leads to increase or decrease in swelling and shrinkage ratio. These
variations can be minimized by admixtures such as Quick lime, Marble Dust, Kota- Stone Slurry, Rice Husk Ash and
Fly Ash. The present study deals with evaluation of physical and engineering properties of expansive soil which is
mixed with admixtures in a varying proportions and the results by comparing it with standard codes and practices.
The experimental study also revealed that with the increase of percentage of different admixtures like Quick lime, Fly
Ash, Marble Dust, RHA and Kota Stone Slurry there is an increase in Maximum dry density values where as there is
considerable reduction in optimum moisture content for the given soil by conducting standard proctor test also with
the conduction of CBR test by varying the percentage of admixtures like Lime, Marble Dust, RHA, Kota Stone Slurry
and Fly ash in the soil mix, there is a gradual increase in the CBR values with the increase in percentage of
stabilizers.
