Challenge Problems
Push your limits with advanced challenges
Design a curve with a radius of 600m allowing a design speed of 100 km/h. Calculate superelevation and check all parameters.
💡 Hint: Check your calculations against the IRC maximum values.
A two-lane road's outer edge needs to be raised. Given the radius is 500m, determine how much elevation is required if e is 0.06.
💡 Hint: Use the rotation method for elevation adjustments.
