The grade compensation on a horizontal curve of radius 50 m on a hill road with ruling gradient 5% will be

The compensated gradient on a horizontal curve of radius 80 m on a hill road having ruling gradient of 6.5% will be

A valley curve is formed by a descending gradient of 1 in 30 meeting an ascending gradient of 1 in 20. Calculate the length of valley curve for comfort condition if design speed on the curve is 70 kmph. Assume coefficient of centrifugal acceleration to be 0.54 m/s³.

A vertical summit curve is to be formed at the intersection of two gradient +5% and -4%. Design the length of summit curve to provide stopping sight distance of 135 m.

A valley curve is to be formed having a deviation angle of 1 in 15. Calculate the length of valley curve for a design speed of 55 kmph. Assume allowable rate of change of centrifugal acceleration is 0.65 m/s³ and stopping sight distance required on the curve is 75 m.
