NCHRP's "Full-Depth Reclamation" (FDR) report documents current practices used by state DOTs, including classification of FDR types, site selection, specifications, and guidelines for mix design and test methods to evaluate FDR quality.
Full-depth reclamation is a method to recycle in-place asphalt material for reconstruction and rehabilitation of flexible pavements, which utilizes existing asphalt concrete and base layers as the base layer for a new surface wearing course. The environmental and economic performance of pavement can be improved by optimizing the reuse of in-place materials, thus minimizing construction time and associated traffic disruptions.
While FDR is a widespread practice across the U.S., state DOTs employ diverse construction practices and quality assurance procedures. The primary objective of this synthesis is to document the current state of DOT practices and procedures related to the use of FDR.
The National Cooperative Highway Research Program conducts research in problem areas that affect highway planning, design, construction, operation, and maintenance in the United States.
Administered under the Transportation Research Board (TRB), NCHRP is a collaborative effort between the Federal Highway Administration (FHWA) and the National Academy of Sciences.
