Question 6

In case of governing equations for calculating wheel load stress using Westergaard’s approach, the following statements are made.
Statement-I: Load Stresses are inversely proportional to wheel load.
Statement-II: Modulus of subgrade reaction is useful for load stress calculation.
Which of the following options are correct?

Question 7

The rigid pavement are made of

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.
