1. A 1600 ft long sag vertical curve (equal tangent) has a PVC at station 120+00
and elevation 1500 ft. The initial grade is -3.5% and the final grade is +6.5%.
Determine the elevation and stationing of the low point, PVI and PVT.
2. A 500 ft long equal-tangent crest vertical curve connects tangents that intersect
at station 340+00 and elevation 1322 ft. The initial grade is +4.0% and the final
grade is -2.5%. Determine the elevation and stationing if the high point, PVC, and
PVT.
3. A +5.1% grade intersects a -2.8% grade at station 68+70 at elevation of
327.50 ft. Calculate the centerline elevation for every 100 feet and station
for a 500 feet vertical curve.
4. The preliminary design of a vertical curve shows the following elements:
G1=-4.2%, G2=+1.6%, Station PVI= 16+70, Elevation PVI-608.99', and
Design Speed-60 mph
Find:
a. The minimum length of the curve
