A crest vertical curve connects a +4.90 percent grade and a -1.85 percent grade. The PVI is at station 77+00.00 at an elevation of 770.00 ft. The design speed is 60 mi/h. Determine: a. The length of the vertical curve using the AASHTO method ("K" factors) b. The station of the BVC c. The elevation of the BVC d. The station of the EVC e. The elevation of the EVC f. The station of the high point g. The elevation of the high point h. The elevation of station 75+30.00 Also, provide a tabulation showing the elevations at each full station on the curve, including the distance from the PVC for each full station, the elevation on initial tangent, the offset, and the elevation on the vertical curve.
