Which feature primarily distinguishes a flexible pavement from a rigid pavement?
Correct answer: C. It distributes loads mainly through layered granular action
- A. It requires reinforcement in every pavement layer
- B. It distributes loads mainly through slab flexural action
- C. It distributes loads mainly through layered granular action
- D. It transfers wheel loads directly to the subgrade
Explanation
Flexible pavement spreads wheel loads progressively through its bituminous and granular layers by grain-to-grain contact. Rigid pavement relies mainly on the flexural strength and slab action of concrete.

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.
