| Cement Concrete and high type bituminous surface | 1 in 50 | 1 in 60 |
| Thin Bituminous surface | 1 in 40 | 1 in 50 |
| WBM, gravel pavement | 1 in 33 | 1 in 40 |

Additional Information
-
Camber is the transverse slope given to the surface of the road to facilitate drainage of surface water toward the sides and prevent water accumulation on the road.
-
It is usually provided in a convex shape, meaning the center of the road is higher than the edges, allowing water to flow off the pavement quickly.
