On a section of an existing highway, a vertical alignment is used. The two grades (-4% and +2%) are joined with a symmetrical parabolic curve of 200 m length. Determine the vertical clearance (in meters) required between the pavement surface (within the vertical curve) and a structure above it. - Height of eye = 2.4m. - Height of object = 0.6m. - Perception-Reaction time = 2.5 sec. - Design speed = 110 kph.
