Full-Depth Reclamation

Full Depth Reclamation
Full depth recycling or full depth reclamation (FDR), is a process that rebuilds worn out asphalt pavements by recycling the existing roadway.
Old asphalt and base materials are pulverized using a specialized machine called a reclaimer. On top of the pulverized material, water is added to reach the optimal moisture content for compaction and then a variety of materials, such as dry cement, lime, fly ash, or asphalt emulsion are incorporated for stabilization. A reclaimer is used again to mix all the materials. After shaping and grading, the new base is compacted to produce a strong, durable base for either an asphalt or concrete surface.
