A cement concrete pavement of a certain thickness laid over a sub grade has a radius of relative stiffness 85 cm. If the thickness of the pavement were to be doubled, what would be the percentage reduction in the flexural stress by the Westergaard's corner load formula under wheel load P. Given that the area of the tyre contact (assumed circular) is 1540 sq. Cm.
