Calculate the super elevation to be provided for a horizontal curve of radius

50 m

for a design speed of

40 k m p h

in snow bound hilly terrain. What is the maximum super elevation that can be provided and what will be the coefficient of friction then? Is the design safe? If it is not safe, what remedy do you suggest?

] = [0.1019,

restricted

t o 0.10

which is greater than

0

15,

hence not safe. Remedy is to increase the radius or post road sign restricting the speed.
