In Kentucky, the roads are comprised primarily of two types of pavement. The first being Portland Cement Concrete (PCC) a rigid pavement, and the other is Asphaltic Concrete (AC), a flexible pavement. There is a noticeable difference in their appearance, ride, cost and performance. Since Kentucky utilizes both pavements, as many states do, it is necessary to have a system in place to consistently identify pavement distress and categorize their overall performance.
