About this document
Elevation Calculation for PVT in Vertical Curve by Johnclaude Chamandi is a document available to read on EtoBox.
The document provides the steps to calculate the elevation of a point of vertical tangent (PVT) given information about the grades and location of a vertical curve. It is determined that for a 70 mph curve with an initial grade of +2%, final grade of -1%, and high point of 1011.4 ft, the elevation of the PVT is 1008.93 ft. This is calculated by first finding the minimum length of the curve, then using that to determine the stationing of the high point from the PVC and PVT, and finally applying the grade to
