Problem #4: Vertical curve

A vertical curve is define by gradient lines. The gradient of the back tangent is +4.2% and the

gradient of the forward tangent is -3.75%. The BVC station is at 45+00 and has an elevation of

215.00 feet. For a vertical curve with a length of 12 stations, determine the following:

a. The station and elevation of the PVI.

b. The station and elevation of the EVC.

c. The elevation of the vertical curve at station 48+00.00.

d. The station and elevation at the high point of the vertical curve.
