Question 8
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.
Question 9
Consider the following statements:
Statement 1: In rigid pavements, the flexural strength of the slab is utilized to resist the loads.
Statement 2: In rigid pavement, major criteria for failure is due to the stresses generated by wheel load action and temperature variations.Question 10
Calculate the frictional stresses developed in a cement concrete pavement slab having a weight density of 2400 kg/m3. The length of the pavement slab is 3.5 m. Assume the coefficient of friction to be 0.15.
