Problem 2.
A new interstate highway is being built with a design speed of 70 mi/h. For one of the horizontal curves, the radius (measured to the
innermost vehicle path) is tentatively planned as 2500 ft. What rate of superelevation is required for this curve? Note: g = 32.2
ft/s² and fs = 0.10.
PROBLEM 7
A +2 percent grade on an arterial highway intersects with a -1 percent
grade at station 535 + 24.25 at an elevation of 300 ft. If the design speed of the
highway is 65 mi/h, determine the stations and elevations of the initial point of
vertical curve (PVC), the final point of vertical curve (PVT), the high point, and the
elevation of each 100-ft station.
A horizontal curve is to be designed for a section of a highway having a design speed of 60 mi/h. (a) If the physical conditions restrict the radius of the curve to 500 ft, what value is required for the superelevation at this curve?(b) Is this a good design?
