Construction of any civil engineering structural project (whether it is building, bridge, dam or road etc) is done on or below the surface of earth. The main purposes of any structure is to transmit the load to the soil beneath, so the soil beneath should be strong enough to bear the upcoming loads without undergoing any failure. Construction of any structure over a weak soil is highly difficult and unsafe as the soil undergoes differential settlements due to high compressibility and poor shear strength. Hence it is most important for us to check the engineering properties of soil before construction.Sub grade is the underlying soil that supports the applied wheel load .
