Although the Perpetual Pavement Concept was first articulated in 2000, many asphalt pavements that were constructed long ago function as Perpetual Pavements.

For example, many full-depth and deep-strength pavements were built around the country in the 1960s and 1970s.
Perpetual Pavement Award Nomination Form
The Asphalt Pavement Alliance instituted the Perpetual Pavement Award program in 2001 to recognize State Agencies and other owners of pavements that had the foresight to build pavements according to these principles. To qualify for the award, the pavement must be at least 35 years old and must have never had a structural failure.
The first winner of a Perpetual Pavement Award was the New Jersey Turnpike, which was 50 years old at that time. Between 2001 and 2013, a total of 93 pavements qualified for the award. Winners include interstate highways, rural roads, and airport runways. The easternmost winner is in Connecticut, and the westernmost is on one of the Aleutian Islands in Alaska.
  • In addition to having served for 35 years with no structural failure, additional requirements for the award include:
  • Pavement must have hot-mix or warm-mix asphalt binder and surface layers.
  • No rehabilitation or series of rehabilitations over the preceding 35 years that has increased the total pavement thickness by more than 4 inches. Thus, the overall structural gain during the 35 years of a pavement’s life preceding the nomination cannot be more than 4 inches.*
  • Resurfacing intervals of no less than 13 years on the average.*
  • Minimum project length is two (2) miles for all roadway types.
  • In the case of “staged construction,” the 35-plus year time frame against which the award criterion is evaluated begins when all stage construction is completed.

Perpetual Pavement Award Nomination Form for Municipal Roadways
Until now, the Perpetual Pavement Award program focused mainly on Interstate/US and State routes, Turnpikes, Farm to Market roads and Airports. This year we are excited to announce award criteria for Municipal Roadways and Residential Streets. To qualify these pavements must be at least 35 years old with no structural failures and a minimum project length of 1,200 feet (or 4 continuous blocks).
Municipal streets are noted for undergoing extreme traffic loading conditions and asphalt pavements have provided years of service to municipalities throughout the US. This award intends to recognize those pavements that have demonstrated outstanding performance.
