Abstract

Full Depth Reclamation (FDR) allows old deteriorated asphalt pavements to be recycled and stabilized with an additive, creating a new base that will provide an excellent foundation for long-term pavement performance. The principal stabilizing additives in use today for FDR are cement, asphalt emulsion, foamed asphalt, and lime/fly-ash. This paper will briefly discuss the differences in how the stabilizing additives work, and present in detail the specific use of cement in the FDR process. The concept of recycling existing pavement materials is especially attractive in locations where quality aggregates may not be readily available. Cost savings and environmental benefits result from use of existing pavement materials, reduced hauling associated with removing old materials and placing new materials, and from the longer expected life of a pavement with a cement-stabilized base. The paper will include the engineering and construction steps involved in designing and building a reclamation project, with examples of successful projects in northern climates.
