hello, I am having an issue with a question in my highway engineering course.
the question is:
An equal tangent sag vertical curve has an initial grade of –2.5%. It is known that the final grade is positive and that the low point is at elevation 82 m and station 1 + 410.000. The PVT of the curve is at elevation 83.5 m and the design speed of the curve is 60 km/h. Determine the station and elevation of the PVC and PVI.
