A developer is having a single-lane raceway constructed with a 200-mi/h design speed. A curve on the raceway has a radius of 4500 ft, a central angle of 30 degrees, and PI stationing at 1125 + 10.
If the design coefficient of side friction is 0.20, determine the super elevation required at the design speed (do not ignore the normal component of the centripetal force).
Also, compute the degree of curve, length of curve, and stationing of the PC and PT.
