A +4.2 percent grade intersects a -3.1 percent grade at station 52+41.34 (i.e. the PVI station) at an elevation of 327.50 ft (i.e. the PVI elevation). The curve is 650 ft long. Calculate the centerline elevations for every 100-ft station (i.e. 51+00, 52+00, 53+00, etc.). Calculate the station and centerline elevations for the PVC, PVT, and low/high point on the curve. Sketch the curve; be sure to label the PVC, PVI, and PVT. Is this a sag or crest curve?
