The rising gradient is change 0.025 and falling 0.013333 beginning tanget elevation is 21.85 and end tangent elevation is 24.18.

How it will be parabolic?

In highway engineering, we deal with two type of vertical curves summit and valley.
IRC CLEARLY have defined the ideal vertical curves for summit it is circular and for valley it is cubic.

How it is happen? Please explain.

A cubic spiral is suitable to cubic parabola but latter is used mostly because of its ease in setting out. Vertical curves are provided to negotiate the gradient of the two straights. Parabola is most suitable shape for vertical curves since it provides a uniform rate of change of gradient and smooth riding condition.

Ideal curve is circular as per irc code.

Curves are two types they are Summit curve and valley curve.
And the best ideal curve is Summit curve.
And the best ideal curve is Summit curve.

Because the parabolic curve can be either sag or summit curve, in both the cases parabolic curve provides the best curve to provide maximum comfort to the passengers pr driver.

Correct answer is circular.
Ideal summit curve is circular. But IRC recommend parabola.
