1. A 4% ascending grade intersect a descending grade at the vertex, V, at station 3 + 500 and at elevation 300 m. The intersecting tangents are connected by an unsymmetrical parabolic curve passing through point X at station 3 + 530 having a curve elevation equal to 296.415 m. The elevation of PT is at elevation 291.6 m and the length of curve on the side of the forward tangent is 120 m. Determine the length of curve on the side of the back tangent, the stationing and elevation of the highest point on the curve. 1.
