Generally, for thin bituminous pavements, the minimum camber should be 2.5% to cater for drainage of the surface runoffs.

In the hilly area where we can provide a minimum of 2.5% camber,& maximum of 10% camber.

Although 7% is max required for the road as per ISI. But in hill road, we can avoid as per position.

Hilly mean heavy rainfall area.

Ajay said:   7 years ago
For camber.

In CC road it is 1 in 50.
Thin bitumen 1 in 40.
Gravel 1 in 33.
Earthen 1 in 25.

Camber for the thin bituminous surface.

In high rainfall - 2.5% or 1 in 40.
In light rainfall -2% or 1 in 40.

Hill roads = Heavy Rainfall = 1in 40 = 2.5.

CC/High Bituminous road - 1.7%(light rainfall), 2%(heavy rainfall).
Thin Bituminous road - 2%(light rainfall), 2.5(heavy rainfall).
WBM/gravel road - 2.5%(light rainfall), 3%(heavy rainfall).
Earthen raod - 3%(light rainfall), 4%(heavy rainfall).

Please, anyone, tell me what is the max limit of camber in hilly roads.

Avnish said:   6 years ago
If the crown is provided then there would be tension in upper and concrete are weak in tension, the crack will produce.
