Long-Life Pavements, traditionally called Perpetual Pavements, are multi-layer pavement designs built from the bottom up, with each layer engineered to maximize pavement life. Long-Life Pavement designs provide agencies with an approach that reduces the life-cycle costs of a pavement. With this approach, asphalt roads can be built with a structure that lasts many decades with only periodic surface renewal and maintenance required, making it an ideal choice for drivers, engineers and the traveling public.
