Full Depth Reclamation (FDR) is an engineered rehabilitation technique. The <br />entire thickness of the asphalt pavement and a predetermined portion of the underlying materials <br />(base, subbase, and subgrade) is uniformly pulverized and blended to provide an upgraded, <br />homogeneous material. The reclaimed materials may be improved and strengthened by using <br />Mechanical, Chemical, or Bituminous stabilization. FDR isn't only for roads in poor condition; it is also <br />a viable design process for increasing pavement's structural capacity in good condition but requires a <br />lot of upfront coordination with various utility agencies to ensure that there are no utility facilities <br />within the existing asphalt and underlying materials that will be pulverized. <br /> <br />Reconstruction <br />Pavement reconstruction is a treatment that is needed when a road has reached the end of its design <br />life, or the pavement has severe cross-section deficiencies due to traffic or environmental factors. <br />These roads typically have a PCI of 25 and below; reconstruction is required to restore the service life. <br />Reconstruction is equivalent to a new pavement that involves rebuilding the pavement layers from the <br />ground up to replace the pavement. This treatment is the most expensive compared to the other <br />treatments in the maintenance strategy. <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br />12 https://roadresource.org/treatment_resources/full_depth_reclamation <br />Page 190 of 228
