Example 2: A crest vertical curve joining a +3% grade and a -2% grade is to be designed for a two-lane highway with a design speed of 60 mph. If the tangents intersect at station (187+40.00) at an elevation of 180 ft., use the K-value to find the length of curve and determine the stations and elevations of the PVC. Also, find the location of the high point. Give: u 60 mph; G₁=+3.0 % %; G2=-2.0%; STAPVI = 187+40.00; Epv1 =180 ft.
