For a pavement of width 7.5 m if the crown in 6.25 cm, the camber provided is 1 in
60

Solution

The correct option is A 60
Camber can be of straight type or parabolic type or a combination of both
However for a given camber (1 in N), the value of crown is same for both straight and parabolic camber.

For straight line camber
$y = \frac{W}{2 N}$
$0.0625 = \frac{7.5}{2 N}$
$N = 60$
Hence, camber is 1 in 60
