How to derive formula for super elevation or road bending
By going through the following construction video, you can learn the tips for obtaining formula toward full super elevation of highway or road. This video is very useful for land surveying.
Full super-elevation stands for the amount with which the external edge of a curve located at a road or railway is grounded directly above the inner edge. Its units range from meter/meter or feet/feet.
In order to neutralize the consequence of centrifugal force as well as decrease the trend of vehicle to overturn and to slide laterally outsides, pavement outer edge is elevated in regard to inner edge. Consequently, delivering a transverse slope is called Super elevation.
The formula is used for full super elevation = h = Bv2/gR
