Full Depth Reclamation (FDR) is an economical, in-place recycling alternative to road reconstruction. It uses a powerful reclaiming machine to turn an old asphalt pavement into a road base by uniformly pulverizing that full thickness of the old pavement and blending it with a portion of underlying material. This process usually adds bituminous emulsion, chemical or mechanical stabilization agents to enhance the strength of the new base that is sealed with an asphalt friction course or a sealing treatment, depending on expected loads. The process allows for correcting drainage and cross slope problems, as well as widening the roadway.
It makes sense when a pavement can't be salvaged with milling, overlaying, or recycling techniques due to severe pavement defects, poor drainage, or an inadequate base.
Road Reclamation is not needed when the existing pavement can be preserved with lesser interventions, such as a Milling and Overlay process.
