What is maximum & minimum gradient according to IRC?

1:60, 1:75gradient is wrong or right according to IRC?

Deekshith said:   7 years ago
According to IRC, grade compensation is not provided for gradients flatter than 4%.

Sam said:   7 years ago
3% is the answer.

Actual Percent - (75/R) = 3 - (75/300) = 3 - 0.25 = 2.75.

Although Grade compensation = 30 + R / R = 1.1 and maximum limit of grade compensation = 75/ R = 0.25 but less than 1.1 so,

Compensiated grade = 3% - 0.25% = 2.75% which is less than 4%.

Please, Justify the necessity of grade compensation in a hilly area.

G.p.gausinha said:   6 years ago
Option E is correct because given gradient is 3% while grade compensation is provided if gradient is greater than 4%.

Vaibhav said:   6 years ago
As per IRC,
If R> 45 use75/r , otherwise 30+r/r.

Grade compensation is not provided below 4% so, the answer is E.
