Soil compaction is a process of mechanical densification of soil by pressing the soil particles close to each other and removing the air between them. It is of utmost importance in the broad science of Geotechnical engineering playing a significant role in all types of Geotechnical investigations. The principle soil properties affected by compaction include the shearing resistance. The constitutive equations for volume change, shear strength and flow for unsaturated soil have been generally accepted in Geotechnical engineering (Fredlund and Rahardjo, 1993a). The shear strength of an unsaturated clayey soil and soil-water characteristic curve depend on the soil structure or the aggregation which in turn depends on the initial water content and the method of compaction. The aim of this research work is to determine the cohesion, angle of internal friction of the clay soil based on the moisture content. For this clay soils classified as CH, CI are used. Soil samples are chosen on the basis of soil type and clay content (more than 25%). Maximum dry density and Optimum moisture content is are determined after 24-hour soaking, using light compaction. The hydrometer test are carried out for the grain size distribution. For the present work six different type of clayey soils are consider. The sample are taken from Dahej (02), Surat (02) and Bhavnagar (01). All the sample were tested at OMC & MDD as obtain from standard proctor test. The compaction was done at 0.95,1.00 and 1.05 times of OMC. Each sample were tested for triaxial test as well as direct shear at the strain rate of 0.625 mm/min and 1.25 mm/min. direct shear test and triaxial test are conducted for unconsolidated undrained (UU) condition.
