Description: Reprint of an article from March 2006 issue of Asphalt Contractor magazine, which reports on the use of full-depth reclamation (FDR) to rehabilitate 150 lane miles of secondary roads in South Carolina. More then 450,000 tons of material was processed using Portland cement as the stabilizing material. Using a conventional reconstruction method, 600,000 tons of material would have been trucked out and into the project. The FDR process allowed the width of the pavement to increase to 24-ft from existing widths that varied from 18 to 22-ft. Depth of the stabilized material was typically 8 to 9-in. Surface treatment consisted of two layers of chip seal followed by a final sand sealer coat to hold the aggregate chips in place. According to the District engineer, when 15 to 25% or more of the designated road requires full-depth patching, it generally becomes a candidate fro the FDR process. The article includes a detailed description of the project, equipment, and benefits of FDR as well as quotes from the District engineer and contractor. 4 pages. Sold in packs of 25.
