A backward tangent having a slope of 7% intersects the forward tangent having a slope -4% at stations 6 + 300 having an elevation of 230m. It is required to connect two tangents with an unsymmetrical parabolic curve that shall pass through point on the curve having an elevation of 227.57m at station 6+270. The length of the curve is 60m on the side of the back tangent. Determine the stationing of the highest point of the curve.

Curve setting

A curve is a turn that is provided horizontally or vertically in the design of highways, railways, and runways. A curve connects two straight lines that are separated by the deflection angle. It helps to change the direction and alignment of the highways, railway tracks, and runways. Therefore, the gradual change in their alignment is made by using a curve to provide comfort to the passengers and this also provides an easy turn to change the direction of the moving vehicle.
