Homework Answers
Given,
Design speed,v=60mph=88ft/sec
e=0.04
f=0.12
Radius,R=?
Using relation given below
e+f=v²/(gR)
R=v²/((g)*(e+f))
R=(88²)/((32.1741)*(0.04+0.12))
R=1504.315583ft≈1510ft
Options B 1510ft is most appropriate.

A developer is having a single-lane raceway constructed with a 120 mph design speed. A curve on the raceway has a radius of 1200 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 superelevation required at 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. 4.
