Which pavement distress is identified by longitudinal depressions formed in the wheel paths of an asphalt pavement?
Correct answer: A. Rutting
- A. Rutting
- B. Ravelling
- C. Bleeding
- D. Polishing
Explanation
Rutting consists of permanent longitudinal depressions in the wheel tracks, usually caused by accumulated deformation in the asphalt layers or subgrade. Ravelling is the loss of aggregate particles from the surface.

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.
