What are the best practices for identifying and excavating the repair area during a full-depth reclamation treatment?

Full-depth reclamation, or FDR, can be a more cost-effective, durable, and environmentally-friendly option to rehabilitation or removal and replacement techniques. FDR addresses problems with the base or subgrade, typically indicated by depressions, pumping, bottom-up fatigue cracking (thin pavement structure), and underlying stripping.
Example of fatigue cracking that can be addressed by FDR.
According to the Pavement Preservation and Recycling Alliance, FDR:
  • Is 40 to 80% less expensive than alternative reconstruction techniques.
  • Allows for same-day road reopening to light traffic.
  • Reuses up to 100% of existing materials.
  • Limits importing and exporting of materials reduced by as much as 90%.

Identify the Repair Area:

The first step in FDR construction is to identify the area to be repaired. The entire distressed area needs to be removed with repairs extending 12 inches into non-distressed pavement. (Note that the condition of the pavement is usually worse at the bottom than at the top!)

Other Tips:
  • Mark straight boundary lines with areas as rectangular as possible. It is difficult to get good density at corners.
  • On moderately-to-heavily trafficked roads, do not mark a boundary in the 2.5-foot zone that defines the wheel path.
  • Avoid leaving a thin strip of asphalt pavement (less than 18-inches wide) along the pavement edge. Thin strips of asphalt pavement along the pavement edge tend to crack and deteriorate faster under traffic loading. It is better to extend the repair to the pavement edge.
  • Verify the patch boundaries are wide enough to accommodate both the removal equipment and the compaction equipment.


For small patches, use a jackhammer with a spade bit or a masonry saw. Make vertical cuts through the full depth of the asphalt pavement surface. If a jackhammer is used, work from the center of the patch area outward to avoid damaging good pavement.


Avoid leaving small areas between repairs.

For medium to large patches, use a diamond-bladed saw to cut the edges. If the distress is only at the surface and the pavement is thick enough, consider a partial-depth cut for thick asphalt pavement surfaces to retain some interlock with the remaining structure.

Be sure to remove all of the defective material in each distressed area using a backhoe. Do not leave a small area between repairs. To avoid damaging the sound pavement, the material needs to be removed starting at a location away from the boundary.


Milling is effective at removing certain types of surface distress that can affect the performance of an overlay, such as rutting, surface wear, and cracking. Milling is sometimes needed to remove not only the surface but underlying bound layers to correct problems with rutting, stripping, and other severe forms of pavement deterioration. Some milling machines can remove up to 14 inches of pavement for the full lane width in one pass.
