Question

15 points) A horizontal curve is being designed for a new two-lane highway (12-ft lanes). The PI is at station 250 00, design speed is 65 mph, and a maximum superelevation of 0.08 ft/ft is to be used. If the central angle of the curve is 35 degrees, design a curve for the highway by computing the radius and stationing of the PC and PT.

Answer 1

Answer:

59.78 m

Explanation:

Data:

PI station = 250 will allow a speed of 65 mph

The maximum superelevation will be  = 0.08 ft/ft

Central angle of the curve                    =  35 degrees

A figure will be used to present the information. This gives the height of 59.78 m as the maximum elevation for the safe speed of the vehicle.
