What Is Gradient of Road?

The gradient is the rise and fall of the gradient with respect to the horizontal line. Gradients are mainly four types those are-

Types of Gradient of Road

Gradients are mainly categorized into six categories, those are-

1. Limiting Gradient of Road

Limiting gradient is that type of gradient which is steeper than the ruling gradient. This limiting gradient is mainly used in rolling terrain and hilly terrain. This gradient is also known as a maximum gradient.

2. Ruling Gradient of Road

The ruling gradient is that type of gradient which is used to make the alignment of the road. This is adopting widely because this gives maximum safety at minimum cost.

3. Exceptional Gradient of Road

Exceptional Gradient is that type of gradient which is steeper than limiting gradient, this is used only for special situations. This gradient is adopted in an unavoidable situation like mountainous terrain that’s why the gradient is steeper ad it causes more fuel requirement and frictional losses.

4. Average Gradient of Road

The rate of fall or rise between two points along the road alignment is known as an average gradient.

5. Floating Gradient of Road

The floating gradient is a gradient where vehicles are moving smoothly with constant speed without using braking or other application.

6. Minimum Gradient of Road

The minimum gradient is that type of gradient where we provide a minimum slope for drainage purposes of rainwater.
