With reference to IRC 58-2011, consider the following statement made:
P. Radius of relative stiffness is directly proportional to \({h^{\frac{3}{4}}}\) (where h is the thickness of cc pavement slab).
Q. Radius of relative stiffness increases with an increase in modulus of subgrade reaction.
R. Radius of relative stiffness decreases with increase in poisons ratio of the cement.concrete.1
