Question

The type of the camber which is best suited for the cement concrete pavement is
1. Straight line
2. Parabolic
3. Elliptical
4. Composite

Answer 1

Correct Answer - Option 1 : Straight line

Explanation:

Camber:

• Camber is the slope provided in the transverse direction of the road to drain off the rainwater from the road surface.
• Usually, a camber is provided in the straight roads by raising the center of the carriageway with respect to the edges forming the highest point at the center.
• The straight slope of the camber is easier to be cast and maintained in the case of concrete pavement.
• Parabolic shaped camber is difficult to construct and maintain. It has steeper edges which are inconvenient to use. However, it is kept in bituminous pavements for better drainage of water.
