Description

While perpetual pavement (PP) concepts received heavy attention about 15 years ago, many states continue to apply the concepts to pavement design. Perpetual pavements are intended to last 50 years or more with treatments limited to the top 2 to 3 inches of pavement. To do this, designers specify materials properties and thicknesses that will preclude bottom-of-layer stresses from exceeding elastic limits. The concept can be applied to new and existing pavements. Advancing perpetual pavements requires design beyond AASHTO 93, DARWIN and MEPDG concepts.

This presentation will cover:

  • Design considerations
  • Identifying existing pavements as candidates for PP
  • Case examples from around the country
  • Typical surface treatments used for PPs
