Question: A 400 m vertical curve connects a -2.00 % grade to a +4.00% grade. The PVI is located at station 150+00 and elevation 60.00

A 400 m vertical curve connects a -2.00 % grade to a +4.00% grade. The PVI is located at station 150+00 and elevation 60.00 m above sea level. A pipe is to be located at the low point on the vertical curve. The roadway at this point consists of two 3.6 m lanes with a normal crown slope of 2%. If the lowest point on the surface of the roadway must clear the pipe by 0.75 m, what is the station and maximum elevation of the pipe?
