Question

A reverse curve is being designed to join two roadways whose centerlines are parallel and 72 ft apart. The two simple circular curve components are identical. The line connecting points x and y in the figure is 500 ft long; line x-y is tangent to the curves at the PRC. The station of the PI1 for the first component curve (point x) is 23+45.67

Determine:

 The central angle of each component curve

 The length of each component curve

 The station of the PRC

 The station of the PT
