Example for Finding Edge of Pavement Elevation | Horizontal and Vertical Alignment for Highways 

CORRECTION: At 1:51 and 2:25, -0.183 should be -0.0183. The answer is correct, but the number is shown in the equation incorrectly (i.e., -1.83% is equal to -0.0183, NOT -0.183).
Determine the outside edge of pavement elevation at station 41+00 and the inside edge of pavement elevation at station 51+50. The curve has a design superelevation of 6.6%. The highway has a constant -1.83% longitudinal grade throughout this two-lane section with 12’ lanes, and the centerline of the highway has an elevation of 1,984.61 ft at station 38+00.
