— The Aim of this paper to define improvement of California Bearing Ratio of Sub grade in saline condition in
black cotton soil. Expansive soil have tremendous strength but it become very soft when it getting wet, It expands/swell
due to its mineralogical composition during its wet condition, It creates cracks or consolidated when it is dry. The
stability and performance of the pavements are greatly influenced by the sub grade. Design of Flexible Pavement
according to Indian Road Congress ( IRC) is highly dependent on California Bearing Ratio of Soil. In Black Cotton Soil it
lies between 1-2.5 % which is very low. Low bearing ratio required high Pavement thickness which become very
uneconomical so improvement is necessary. In this paper C.B.R is between 2.0 – 2.5 % which is improved up to 7.8 % in
case Study Area. The Saline soils have excessive concentration of natural soluble salts, mainly of chlorides, sulphates and
carbonates of calcium, magnesium and sodium. The magnesium in magnesium chloride may react with the cement paste
in concrete, weakening the pavement structure. Rutting or Pot holing in granular Pavement & Differential shape resulting
in rough pavement. Both Expansion and Salinity influences pavement failure due to failure in sub grade so it is required
to detail study on stabilization of black cotton soil.
