Camber is the slope of provided on the road surface
in longitudinal direction
in inclined direction
in regular fashion
in transverse direction
in transverse direction
Camber is the transverse slope provided to the road surface to drain off rainwater from the road, preventing water stagnation. It is essential for protecting the pavement structure and ensuring the safety of road users.

Camber(n)=N1=HalfWidthRise — defining the slope ratio of the crown
Camber functions as a drainage mechanism. When precipitation occurs, gravity acts on the water droplets; the transverse slope creates a velocity component perpendicular to the direction of travel, forcing the water to flow towards the shoulders or drainage channels.
Camber is essential for life-cycle maintenance of the road surface.
It helps in reducing the duration of contact between water and pavement, preventing degradation.
The type of camber (Parabolic, Straight, or Composite) depends on the road material and speed.
Concrete and high-quality bituminous roads require less camber than earth roads.
Surface water drainage
Pavement protection
Improved visibility and driving safety
Increased risk of vehicles sliding towards shoulders on high slopes
Difficulty in maintaining uniform shape over time
Highway design
Airport runways
Urban road infrastructure
Standard values vary from 1 in 50 for thin bituminous surfaces to 1 in 25 for earthen roads.
Option A is incorrect because longitudinal slopes are referred to as gradients, not camber.
D is correct — Camber is defined as the transverse slope provided to a road surface to facilitate drainage.
Remember that 'Camber' is for cross-sectional (transverse) slope, whereas 'Gradient' is for longitudinal slope. Confusing these is a frequent error in civil engineering exams.
