The attainment of super elevation by rotation of pavement about the inner edge of the pavement

In flat terrain, the conventional method of achieving superelevation by raising the outer edge of the pavement results in a drainage problem. The raised outer edge of the pavement obstructs the flow of water, leading to the accumulation of water on the pavement, causing skidding and hydroplaning. Rotation of pavement avoids this problem by achieving superelevation without raising the outer edge of the pavement.
