Q: A road pavement should have which of the following qualities?
  • A. Undulation
  • B. Deflection
  • C. Non yielding
  • D. Yielding
Correct Answer: Option C - Non-yielding of pavement– The road pavement must be non-yielding in order to withstand the heavy wheel load and allow the movement of traffic with the least resistance possible. There must be no undulations in the pavement to allow smooth riding and comfort to passengers. • Rigid pavement is the one that has a concrete slab as the topmost layer but in flexible pavement is the one that has bituminous material as the topmost layer and it has negligible flexural strength. • Truncated cone shape is the compressive strength distributed in a flexible pavement.
