WebIt is the maximum gradient within which the designer attempts to design the vertical profile of a road. It is also known as design gradient. As per IRC, the recommended value of ruling gradient for plain or rolling terrain is 1 in 30 or 3.3 %. Exceptional Gradient. Exceptional gradients are very steeper gradients given at unavoidable situations. Weband is most commonly expressed as a percentage.Vertical curves used to effect gradual changes between tangent grades consist of two types, sag and crest, and can either be symmetrical or .
