Maximum Allowable Superelevation on Hilly Roads

Superelevation is the banking of a road or a railway track on a curve. It is done to counteract the centrifugal force that acts on a vehicle or a train moving along a curve. Superelevation is measured in terms of percentage and is denoted by the symbol e. The maximum allowable superelevation on hilly roads not bound by snow as prescribed by IRC is taken to be 10%. Let's understand this in detail.

What is IRC?

IRC stands for Indian Road Congress. It is a professional body that formulates and publishes standards and guidelines for roads and highways in India. It was established in 1934 and is headquartered in New Delhi.

What are Hilly Roads?

Hilly roads are roads that are built on hilly terrain. These roads are characterized by steep slopes and curves. They require special attention in terms of design and construction to ensure safety and comfort for the users.

What is Superelevation?

Maximum Allowable Superelevation on Hilly Roads

The maximum allowable superelevation on hilly roads not bound by snow as prescribed by IRC is taken to be 10%. This means that the road can be banked up to 10% on a curve to ensure the safety and comfort of the users.

Why is Superelevation Important?

Superelevation is important because it helps to counteract the centrifugal force that acts on a vehicle or a train moving along a curve. If the road is not banked properly, the vehicle or the train may skid or derail, leading to accidents. Superelevation also helps to increase the speed of the vehicle or the train on a curve, thereby reducing travel time.

Conclusion

In conclusion, the maximum allowable superelevation on hilly roads not bound by snow as prescribed by IRC is taken to be 10%. This is important to ensure the safety and comfort of the users. Hilly roads require special attention in terms of design and construction to ensure that they are safe and comfortable for the users.
