Curve 2: A +7.00% grade meets a -6.00% grade at station 4+80 and elevation 705.70 ft, 80-ft curve, staked 10ft apart. Get a rough estimate in cubic yards of how much soil that must be brought in (fill) and/or removed (cut) to create a 14-foot wide roadway that starts at your PVC/BVC, ends at your PVT/EVC, and follows your curve elevations. Make sure to state which curve your group was assigned in the calculations. Trapezoidal Area Estimation is key. ground has the following elevations starting from the PC and ending at the PT; 702ft, 703ft, 704ft, 705ft, 706ft, 705ft, 704ft, 703ft,and 702ft.

A 3.0% grade passing at station 19+85.00 at an elevation of 99.10 m meets a -2.0% grade passing at station 20+35.00 at an elevation of 99.60 m. Please note that these two elevations and stations DO NOT correspond to BVC and EVC. Determine the station and elevation of the point of intersection of the two grades./ If the highest point on the curve must lie at station 20+40.00, find the elevation of this point and the length of the curve...

A tangent section of highway has a -1.0% grade and ends at station 0+145 and elevation 26 m. It must be connected to another section of highway that has a -1.0% grade and that begins at station 1 + 350 and elevation 40 m. The connecting alignment should consist of a sag curve, constant grade section, and crest curve, and be designed for a speed of 80 km/h. What is the lowest grade possible for the constant grade section that...
