Question:

Grades of g1 = +5.00% and g2 = +1.50% VPI station 6+300 and elevation 185.920 m. Fixed elevation 185.610 m at station 6+400. (Use 100-m stationing)
Field conditions require a highway curve to pass through a fixed point. Compute a suitable
equal-tangent vertical curve and full-station elevations for the above Problem.
