The main purpose of providing camber on a road surface is to:
Correct answer: B. Drain rainwater away from the pavement
- A. Increase the stopping sight distance
- B. Drain rainwater away from the pavement
- C. Reduce the length of a vertical curve
- D. Provide extra width on a horizontal curve
Explanation
Camber gives the pavement a cross slope that allows rainwater to flow toward the edges. It does not directly determine sight distance, vertical curve length or the widening of horizontal curves.

About Transportation Engineering
Transportation engineering covers highway planning and alignment, traffic studies, road geometric design, pavement materials and flexible or rigid pavement construction. It also includes railway, airport and traffic engineering concepts such as sight distance, superelevation, signals, capacity and level of service, distinguishing pavement failure from poor geometric design.
