👉Road Camber – Engineering for Safer Roads

🔖Definition

🧷Road camber is the transverse slope provided on the road surface.

⏺It ensures rainwater drains quickly, preventing waterlogging and enhancing vehicle safety, stability, and comfort. 

🔰Types of Camber

- Straight (Normal) Camber: Road is raised at the center (crown) and slopes down to both edges. 
  - Advantages: Quick drainage, safe and comfortable driving. 
  - Disadvantages: Minimal under normal conditions. 
- Sloped Camber: Road slopes in one direction only. 
  - Advantages: Ideal for hilly terrain, fast drainage.

✳️Disadvantages
🔖Unsuitable for flat plains, uneven wear possible. 
- Parabolic Camber: Road curves downwards in a parabolic profile from crown to edges. 
  - Advantages: Smooth ride, superior drainage. 
  - Disadvantages: Slightly higher construction cost.

💫Methods of Providing Camber

- Raising the center of the road. 
- Lowering the edges. 
- Combination of both. 
- Proper compaction and surfacing.

🔗Purpose

- Quick drainage of rainwater. 
- Enhanced safety and stability of vehicles. 
- Improved driving comfort.

🪧Results

- Reduced water logging. 
- Increased pavement life. 
- Better vehicle control. 
- Comfortable driving experience. 

🚧Typical Values

- Expressed as a percentage of road width. 
- Highways generally use 2.5% to 4% camber.
