IRC Recommendations for grade compensation:
IRC gave the following guidelines for grade compensations:-
  • Grade compensation is not required for grades flatter than 4% because the loss of tractive force is negligible.
  • Grade compensation is (30+R)/R%, where R – radius of horizontal curve in m.
  • The maximum grade compensation is limited to (75/R)%
Calculation:
Given:
The gradient of the Curve = 

⇒ GC = 0.75%
∴ Compensated Gradient = ((1/25) x 100) - 0.75 = 4 - 0.75 = 3.25%
But, Compensated Gradient (C.G) should be ≥ 4 %
Since the gradient of the curve is 4 %, no grade compensation is required. 
∴ C.G = 4%.
