Pavement designers and contractors have learned that some intersections need special attention. Heavy, slow-moving vehicles that are stopping, turning, or accelerating expose intersections to some of the highest stress levels found on pavements. High-stress locations also include climbing lanes, truck weigh stations, rest areas, and other slow-speed areas. Giving special attention to these areas can ensure that high-stress areas deliver the same outstanding performance as other asphalt pavements. Pavement engineers have adopted a four- point strategy to ensure good performance for intersections and other high-stress applications.
