The Virginia Center for Transportation Innovation and Research, a partnership of the Virginia Department of Transportation (VDOT) and the University of Virginia, has released a report that assesses the condition of three full-depth reclamation (FDR) trial sections constructed by VDOT during the 2008 construction season.
According to the report, FDR has become an increasingly common technology to restore the service life of pavement structures requiring deep rehabilitation and to stretch available funding for pavement rehabilitation. FDR consists of pulverizing the existing bound flexible pavement layers along with a portion of the unbound layers (or all the unbound layers and a portion of the subgrade); adding a stabilizing agent; compacting the mixture; and surfacing with a new bound material layer(s) or surface treatment.
