During midnight in summer the stresses of a pavement are as follows; load stress = 15 kg/cm2, warping stress = 11.5 kg/cm2 and frictional stresses are 3 kg/cm2. Determine the critical stress at the top of the pavement.
The pressure corresponding to 1.25 mm deflection in a plate load test is 0.45 kg/cm2. The modulus of subgrade reaction of the soil is
Statement 1: The load required to cause 2.5 and 5mm penetration in a CBR test is 66 kg and 85 kg respectively. The CBR value of the material is 4.13%
Statement 2:CBR is defined as ratio of load required to penetrate a soil mass to a standard load.
