Camber in the road is provided for
Proper sight distance
Counteracting the centrifugal force
effective drainage
all of the above
effective drainage
Camber, also known as cross-slope, is the transverse slope provided to the road surface to allow for the quick drainage of rainwater from the pavement. It helps prevent water logging, which can damage the road structure and cause skidding due to hydroplaning.

Camber works by creating a higher central point (crown) or a continuous slope from the inner edge to the outer edge of the carriageway. This gravity-driven mechanism ensures that surface water flows laterally towards the shoulders or side drains, keeping the subgrade dry and maintaining the pavement's structural integrity.
Camber protects the road subgrade by preventing moisture ingress.
It enhances safety by reducing the risk of hydroplaning during heavy rainfall.
The amount of camber depends on the type of road surface and intensity of rainfall.
Common shapes include parabolic, straight, or a combination of both.
Protects pavement structure from water damage.
Reduces the risk of accidents caused by slippery surfaces.
Increases the lifespan of the road.
Steep camber can cause vehicles to drift towards the shoulders.
Excessive cross-slope can be uncomfortable for passengers.
Bituminous roads
Concrete pavements
Earthen and gravel roads
For thin bituminous surfaces, a steeper camber is generally preferred.
Option A (Sight distance) is primarily affected by vertical curves, not camber.
Option B (Centrifugal force) is compensated by Super-elevation, not camber.
C is correct тАФ Camber is specifically provided to facilitate effective drainage of rainwater from the road surface.
Remember that while Camber handles transverse drainage, Super-elevation (e) is the specific geometric feature designed to counteract centrifugal force on horizontal curves.
