A vertical curve with a length of 440 feet, and initial (PVC to PVI) grade of +3.9%, and a final (PVI to PVT) grade of +0.7% has a PVC at Sta. 13+60 with a PVC elevation of 521.43 You can assume this road is a two-lane, two way road.
A. Sketch the vertical curve and tangents as described (include PVC, PVI, PVT, G1 and G2).
B. Calculate the PVI station and elevation (show your calculations).
C. Calculated the PVT station and elevation (show your calculations).
D. Calculate the algebraic difference for the curve.
E. Calculate the rate of change (K) value.
F. Calculate the Station and Elevation of the high point on the curve.
