SPR 18-558 Full-Depth Reclamation of Asphaltic Concrete Pavements

Full-depth reclamation (FDR) is a pavemeut rehabilitation technique in which the full thickness of an asphalt pavement and a predetermined portion of the underlying materials (base, sub base, and/ or subgrade) are uniformly pulverized, blended and compacted to provide an upgraded, homogeneous mate1~al resulting in a stabilized base course. The Kentucky Transportation Cabinet (KYTC) has utilized the full-depth reclamation process as a method to treat asphalt pavements exhibiting widespread base failures by utilizing a Special Note for Cement Stabilization. The Cabinet, through a previous SPR study, has organized and consolidated information about FDR to produce an implementable set of guidelines, criteria, and specifications on the topic. *** This Research Program for the period July 1, 2016 to June 30, 2018 is submitted in compliance with the provisions of Section 307 of Title 23, United States Code, and describes programs and operations for planning activities in the Kentucky Transportation Cabinet (KYTC) and the Kentucky Cooperative Transportation Research Program (KCTRP). This program modifies and updates such programs and is specifically intended to reflect the needs of the Kentucky Transportation Cabinet. It is fully expected that products from this program will also have national applications. The University of Kentucky Transportation Center is the main research group for the the Kentucky Transportation Cabinet. The SPR grant is the funding the is supplied each year for the many topics the Center is asked to research for KYTC The KCTRP is concerned with the development and conduct of a comprehensive research program in cooperation with the U.S. Department of Transportation, Federal Highway Administration (FHWA). In addition to research developed in cooperation with FHWA, the KCTRP may perform other services for the KYTC on a nonparticipating basis. The scope of these services could include activities such as research studies and special investigations of various engineering and operation activities. The Research Program and Implementation Advisory Committee (RPIAC), headed by the State Highway Engineer and coordinated through the Research Coordinator, will give direction to the research program.
