Advantages of camber
Short answer
Camber provides quick drainage of rainwater, protecting pavement and subgrade from water damage, reducing potholes and maintenance costs. It improves skid resistance by minimizing water film, enhances lane discipline, and improves road appearance. Excessive camber is avoided due to discomfort and safety issues.
What are the advantages of providing camber?
Camber is the cross slope given to the carriageway on straights to drain rainwater. Its advantages:
- Quick drainage: surface water runs to the side drains, so the pavement dries faster.
- Protects the pavement and subgrade: less water enters the pavement layers and subgrade, so strength and life are preserved; fewer potholes.
- Better skid resistance: reduces water film, aquaplaning and accidents in rain.
- Reduces maintenance cost.
- Improves the appearance of the road.
- Lane discipline: the slope helps drivers keep to their own side of the crown.
(Excess camber is disadvantageous, so values are limited.)
