Q: A high steep camber is NOT desirable to:
  • A. transverse tilt and skid of vehicle
  • B. remove rain water from pavement surface
  • C. prevent entry of water into bituminous pavement layers
  • D. prevent the entry of surface water into subgrade soil
Correct Answer: Option A - Camber–It is the convexity provided to the cross-section of the surface of carriageway and is the difference of level between the highest point known as the crown. The reason for providing camber on the road surface are– 1. To drain surface water 2. To separate the traffic in the two direction 3. To improve the appearance of the road • In general a steel camber is to be preferred in areas of heavy rainfall and flat camber in regions of low rainfall. • It is prevet entry of water into subgrade and bituminous pavement layers.
