In a particular location two ground slopes meet whose grades are -3.92 % and +0.16 %. Authorities decided to construct a road through this location and as a part of this an equal tangent parabolic vertical curve needs to be designed that connects the two ground slopes. The design vertical curve should have an optimized length of 240 m. By surveying the elevation and the station of the vertex point where the two ground slopes meeting are found to be 4+265 and 450.42 m. Compute the station and elevation of the curve's high point and the curve for stake out at an increment of 40 m.?
