Question 1.
Find the required superelevation for a curve with a radius of 200m at a design speed of 60 km/h.
Show hintHide hint
Use the formula e = (0.75v)^2 / gR.
Question 2.
What is the maximum permissible superelevation in hilly terrain?
Show hintHide hint
Refer to IRC guidelines.
3Question 3.
What is the formula for calculating superelevation?
- e = (0.75v)^2/(gR)
- e = (0.9v)^2/(gR)
- e = (0.5v)^2/(gR)
Show hintHide hint
Think of the parameters involved in lateral forces.
4Question 4.
True or False: The maximum permissible superelevation in urban areas is 7%.
- True
- False
Show hintHide hint
Recall the IRC specs for different terrains.
Question 5.
Design a curve with a radius of 600m allowing a design speed of 100 km/h. Calculate superelevation and check all parameters.
Show hintHide hint
Check your calculations against the IRC maximum values.
Question 6.
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.
Show hintHide hint
Use the rotation method for elevation adjustments.
