The construction of any civil engineering structural project (whether house, bridge, dam or road, etc.) is carried out on or below the surface of the earth. The main aim of any structure is to transfer the load to the ground below, so that the soil below can be strong enough to support the coming loads without any loss. The building of any structure on a weak soil is very difficult and dangerous as land undergoes unequal settlements due to high compressibility and low shear strength. It is therefore of the utmost importance for us to test the engineering properties of the soil prior to construction.The current research focuses on improving the shear strength of the soil (which is one of the most technological properties of the soil) by using cement as an additive to minimize subgrade failure. Thus, the present study offers an idea for improving the geotechnical engineering properties of the soil used for subgrade pavement by using an additive that has been blended into the soil to achieve the desired result to fulfil the strength criteria. Similar standards may be extended to roads and airfields with a far stable surface layer. This can be done by combining the sandy soil and the Ordinary Portland Cement with the water and compacting the mixture to produce a stronger composite content. The present investigation therefore defines the behavioural dimension of soils mixed with 0 per cent, 5 per cent, 10 per cent and 15 per cent cement by soil volume to increase soil load bearing capacity. The shear strength and index properties, such as water content, MDD, OMC, Liquid Limit, Specific Gravity, etc., have been calculated and evaluated for the improvement of the pavement subgrade.
