Black cotton soil is the most expansive soil having less bearing capacity and high swell index. Its stabilization
is required to mainly improve the stated properties. It is found that Black cotton soil mainly stabilized using Fly ash, Lime
and Cement. Agricultural wastes are also used to stabilize Black cotton soil, but they cannot be used as a single stabilizing
component. Combination of Bagasse ash with other additives proves to be very effective and cheaper method of
stabilization.Stabilization of soils is an effective method for improvement of soil properties and the pavement system
performance. Plasticity Index is one of the important properties of soil to determine the behavior of soil in presence of water.
The poorest soil among all is Black Cotton Soil (BC Soil). Laboratory test was conducted on black cotton soil treated with up
to 16% Cement KilnDust (CKD) by dry weight of soil to assess its suitability for use as road pavement material.
