Highway Engineering
- The desirable length of overtaking zone as per IRC recommendation is equal to
- On a single lane road with two way traffic, the minimum stopping sight distance is equal to
- Compared to a level surface, on a descending gradient the stopping sight distance is
- Camber in the road is provided for
- The shoulder provided along the road edge should be
- Coefficient of friction is less when the pavement surface is
- When the path travelled along the road surface is more than the circumferential movement of the wheels due to rotation, then it results in
- The stopping sight distance depends upon
- For water bound macadam roads in localities of heavy rainfall, the recommended value of camber is
- The shape of the camber, best suited for cement concrete pavements, is
- Nagpur road plan formula were prepared by assuming
