You are being asked to obtain the length of a vertical curve for the following situation: The location having the vertical curve is aligned under a crossroads at station 199 + 20. The bottom elevation was measured as 158 m above sea level. The PI station is located at 200 + 00 with road centerline elevation of 150 m. The vertical curve is located at the intersection of the tangents with grades -2.5% and 1.5%. The clear distance between the road surface and the overhead structure should be 5.75m. If we know that in five years the road surface will be overlaid with a 100 mm asphalt concrete pavement layer, what should be the length of the curve to allow sufficient clearance now and after five years of service.
