What are the Advantages of Superelevation In Road?


1. It allows running of the vehicle at high speed on a curved path as on a straight path without any danger of overturning and thus results in increased volume of traffic.

2. It provides more or less even distribution of load on wheels and hence uniform stress is offered on the foundation which results in less wear on wheel tyres and springs as well as the economy in maintenance cost of the road.

3. It also helps to keep the vehicles to their proper side on the pavement and thus prevents collision of vehicles moving in opposite directions on a curved portion of the road.

4. It provides drainage of the whole width of the road towards the inner side. Thus, there is no necessity of providing a side drain on the outer side of the road.
