Question
A crest vertical curve connects a +4.44 % grade and a -6.87 % grade. The PVI is located at station 43 + 50.00 at an elevation of 1,240.00 feet. The design speed is 30 mph.
Determine the following:
- The length of the vertical curve using the AASHTO method (“K” factors) (1/8 pts.)
- The station of the PVC/BVC (1/8 pts.)
- The station of the PVT/EVC (1/8 pts.)
- The station of the high point (1/8 pts.)
- The elevation of the PVC/BVC (1/8 pts.)
- The elevation of the PVT/EVC (1/8 pts.)
- The elevation of the high point (1/8 pts.)
- The elevation of station 44+ 23.23 (1/8 pts.)
