A crest vertical curves joining a +3% and -4% grade is to be designed for 90 km/h. If the tangents intersect at station 3+400,00 at an elevation of 76,00 m, determine the stations and elevations of the BVC (beginning of the vertical curve) and EVC (end of the vertical curve). Also calculate the elevations of intermediate points on the curve at the whole stations every 40m.

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.
