Question 2
Consider the following statements in the context of cement concrete pavements.
I: Warping stresses in cement concrete pavements are caused by the seasonal variation in temperature
II: Tie bars are generally provided across transverse joints of cement concrete pavements
The correct option evaluating the above statement is

Question 3
A subgrade soil sample was tested using standard CBR apparatus and the observations are given below
Assuming that the load-penetration curve is convex throughout, the CBR value (%) of the sample is
Assuming that the load-penetration curve is convex throughout, the CBR value (%) of the sample is
Question 4
In a pavement slab of thickness 18 cm the modulus of elasticity of concrete and Poisson's ratio are 3 x 105 kg/cm2 and 0.15 respectively. Plate bearing test shown the pressure of 1.2 kg/cm2 corresponding to 1.25 mm penetration. What is the radius (in cm) of relative stiffness of pavement slab?
Question 5
As per IRC:37-2012, in order to control subgrade rutting in flexible pavements, the parameter to be considered is
Question 6
The stress at interior edge of a cement concrete pavement using Westerguard’s equation is _____kg/cm2. (up to 3 decimal places)
Given, wheel load (P) = 4000 kg
Radius of relative stiffness 
= 50 cm
Pavement thickness (h) = 18 cm
Radius of equivalent resisting section = 11.5 cm
Radius of contact area = 12 cm
