what is superelevation? what are max limit of sperelevation?

Question

Accepted Answer

Superelevation is the banking of a road or highway to counteract the centrifugal force on vehicles during turns.

Superelevation is the slope or banking provided on the outer edge of a road or highway.
It helps vehicles to safely negotiate turns at higher speeds by counteracting the centrifugal force.
The maximum limit of superelevation depends on factors like design speed, curve radius, and type of road.
For highways, the maximum superelevation limit is typically around 6%.
Superelevation is usually achieved by raising the outer edge of the road or by lowering the inner edge.
It is important to design and maintain proper superelevation to ensure safe and comfortable driving conditions.

Accepted Answer

Superelevation refers to the banking of a roadway to counteract the lateral forces experienced by vehicles as they travel around a horizontal curve. In other words, it's the tilt or slope of a road surface to the outside of a curve, which helps vehicles maintain their stability and prevent them from slipping or skidding off the road.

The maximum limit of superelevation is determined by several factors, including the design speed of the roadway, the radius of the curve, and the lateral friction between the tires of vehicles and the road surface. As a general rule, the maximum superelevation for highways is typically limited to 8%. However, some roads may have a higher or lower limit based on specific design requirements. Additionally, the maximum superelevation for low-speed rural roads may be lower compared to high-speed highways, as vehicles travel at lower speeds on rural roads and have a lower risk of losing control.
