- In this video we will learn how to calculate Design Superelevation Rate and Maximum Allowable Speed of Road Using IRC Method
Question: The design speed of a highway is 85 kmph. There is a horizontal curve of radius 200 m on a certain locality. Safe limit of transverse coefficient of friction is 0.15.
Calculate the superelevation required to maintain this speed.
If the maximum superelevation of 0.07 is not to be exceeded, calculate the maximum allowable speed on this horizontal curve as it is not possible to increase the radius.
