Definition ofFull-Depth Reclamation (FDR)
“…technique in which the full flexible pavement section and a
predetermined portion of the underlying materials are uniformly crushed, pulverized, or blended,
resulting in a stabilized base course; further stabilization may be obtained through the use of
available additives.” - Asphalt Recycling and Reclaiming Association
FDR is most appropriate under the following conditions:
■ The pavement is seriously damaged and cannot be rehabilitated with simple resurfacing.
■ The existing pavement distress indicates that the problem likely exists in the base or subgrade.
■ The existing pavement distress requires full-depth patching over more than 15 to 20 percent of the surface area.
■ The pavement structure is inadequate for the current or future traffic.
• Uses in-place materials• Requires little or no
material to be hauled off• Maintains or improves
existing grade• Conserves virgin material• Saves cost by using
