As a roadway designer you are asked to design a horizontal curve for a two-lane road that are 12' wide each. There is an enormous boulder in the way of the construction zone and the minimum distance needed to excavate towards to the center must be solved for. The distance is required to sustain a speed of 55mph at a maximum super-elevation of 10%. Find the minimum distance from the boulder to the center of the road that fulfils the design requirement

Expert Solution
Step 1
Given:-
The width of the two-lane road = 12 ft
The design speed of the curve = 55 mph
The maximum super-elevation = 10%
To determine:-
The minimum distance from the boulder to the center of the road that fulfils the design requirement
