FULL DEPTH RECLAMATION (FDR) OF FLEXIBLE PAVEMENT. Description . This work consists of the Full Depth Reclamation (FDR) process to reclaim existing flexible pavement by pulverizing the bituminous asphalt layers, mixing the pulverized material with the existing base and subgrade layers, and adding a specified amount of cement and water …
Details
Process. FDR is the process of pulverizing the full thickness of the asphalt pavement and a predetermined portion of the underlying materials (base, subbase and/or subgrade) with a reclaimer or recycler. If no stabilizing agents are required, a single pass is often sufficient to uniformly pulverized and blend the materials.

In the milling process, a cold planer typically drives down the street and driving a spiked drumhead into the asphalt, ripping and capturing it. A series of conveyor belts then carry the milled asphalt to the plant. This old asphalt is then mixed with new paving. The milling process does not impact the sub-base, leaving it intact.
