Stripping in an asphalt pavement most directly refers to the:
Correct answer: B. Loss of adhesion between bitumen and aggregate
- A. Permanent deformation of the subgrade
- B. Loss of adhesion between bitumen and aggregate
- C. Formation of transverse concrete cracks
- D. Polishing of railway ballast particles
Explanation
Stripping is the separation of bitumen from aggregate, usually because water weakens the bond. Rutting and cracking are different forms of pavement distress, while ballast polishing is unrelated.

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.
