hello, I am having an issue with a question in my highwayengineering 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 thelow point is at elevation 82 m and station 1 + 410.000. The PVT ofthe curve is at elevation 83.5 m and the design speed of the curveis 60 km/h. Determine the station and elevation of the PVC andPVI.
