• A vertical curve joins a -1.2% grade to a + 0.8% grade . the PVI of the vertical curve is at station 75+00 and elevation of 50.90m. the centerline of road way must clear a pipe located at station 75+40 by 0.80m. if the elevation of the pipe is 51.10m. a. determine the minimum length of the vertical curve that can be used b. check the length of the vertical curve determined above if sufficient for SSD of 180m c. determine the station and elevation of PVC,PVT and the highest/lowest point d. prepare the setting out data at 20m full station
