What is "Perpetual Pavement"?

"Perpetual Pavement" is the name coined to describe a three-layer, flexible pavement design and construction concept. Application of the concept produces a deep-strength asphalt pavement that can resist structural fatigue distress for a long time (at least 50 years) and, thus, results in a long-lived pavement.& These long-lasting structural bases can be economically maintained by replacing just the surface, never needing total removal and replacement.

For more information on the "Perpetual Pavement" concept, see the Perpetual Pavement section on Asphalt Pavement Alliance.
