| Choose the correct option:

A. Grade compensation is not necessary for gradient flatter than 3%.

B. Ideal shape of summit curve is circular because sight distance available throughout remains constant.

C. For large deviation angle circular curve and parabolic curve are same.

D. Valley curve consists of two transition curves along with circular curve in between them.

Please scroll down to see the correct answer and solution guide.

Grade compensation is not necessary for gradient flatter than 4%.

Ideal shape of summit curve is circular because sight distance available throughout remains constant.

For small deviation angle circular curve and parabolic curve are same.

Valley curve consists of only two transition curves and no circular curve in between them.
