Problem 4: Vertical Alignment (35 points) Note: You are allowed to use Excel for calculations and present the results in a tabular form. Vertical alignment data of a section of a highway corresponding to the roadway centerline is given in Table 4.1. Table 4.1: Vertical Alignment Data PVI Number PVI Station Elevation (ft) Vertical Curve Length (ft) Outgoing Grade Beginning of Section 11+25.00 1103.35 1 31+33.00 1037.09 534.75 2 1076.09 388.85 47+25.00 55+05.00 3 1125.23 643.50 4 81+15.00 1031.27 554.40 +2.00% a) Determine the incoming and outgoing vertical curve grades for each curve b) Determine A and K of vertical curves c) Determine the stations of PVC and PVT points Problem 4: Vertical Alignment (35 points) Note: You are allowed to use Excel for calculations and present the results in a tabular form.
