The Kentucky Transportation Cabinet (KYTC) has used a full-depth reclamation (FDR) process over the past few years to rehabilitate asphalt pavements exhibiting widespread base failures. FDR transforms existing hot-mix asphalt (HMA) pavement and underlying granular materials into a stabilized base layer. The stabilized layer is then overlaid with a new pavement surface layer. Until now, deciding when and how to use the FDR process has not been well specified in Kentucky — the Cabinet has commonly used a Special Note for Cement Stabilized Roadbed as guidance and relied on the contractor for acceptable materials design. Previous research conducted by the Kentucky Transportation Center (KTC) and funded by KYTC proposed guidelines for FDR pavements and considered various binding compounds including, cement, asphalt emulsion, and foamed asphalt. Guidance also included a process for identifying potential projects for the FDR process and recommendations for examining material sampling, testing, mixture design, structural design parameters, and selection requirements for FDR treatment established through preconstruction planning activities. It also addressed quality control and quality assurance. This report builds on those guidelines by providing a special note for the use of the FDR in Kentucky.
