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 statements is
I: True II: False
I: False II: True
I: True II: True
I: False II: False
Given that r=radius of load distribution E=modulus of elasticity of concrete K=modulus of subgrade reaction μ=Poissons’s ratio of concrete h=thickness of slab P=wheel load
The combination of parameters required for obtaining the radius of relative stiffness of cement concrete slab is
E,K,μ,r
h,K,μ,r
E,h,K,μ
P,h,K,μ
