na certain road construction, it was decided to connect a forward tangent of 3% and a back tangent of -5% by a 200m symmetrical parabolic curve. It was discovered that the grade intersection at station 10+100 whose elevation is 100m falls on a rocky section with an outcrop of 2.67m directly above the grade ntersection. To avoid rock excavation, the project engineer decided to adjust the vertical parabolic curve in such a way that the curve will just clear the rock without altering the position of PVC and the grade of the tangents.
