2.
If d is the thickness of a concrete pavement, the equivalent radius b of resisting section for an interior loading, is
b = 0.6 + d2 - 0.675 d
b = 1.6 + d2 + 0.675 d
b = 1.6 + d2 - 3.675 d
b = 1.6 + d2 - 0.675 d

If x% is the gradient of an alignment and y% is the gradient after proper superelevation along a curved portion of a highway, the differential grade along the curve, is
(x + y)%
(x - y)%
(y - x)%
(x x y)%
(y + x)%
