Investigation of Performance Requirements of Full Depth Reclamation Stabilization

The Minnesota Department of Transportation (MnDOT) recognizes the value of stabilized full-depth reclamation (SFDR) recycling practices and wishes to promote further use of SFDR in its state. Before widespread application of SFDR is attainable, it is imperative that the performance requirements for SFDR be determined. Since there is an absence of such a specification in Minnesota, the structural capacity of SFDR may not be fully attained. The objective of this research project is to determine optimal properties that SFDR material should attain to be used as a base layer for hot-mix asphalt (HMA) roadways. Optimum SFDR material properties are achieved when rutting and low temperature cracking is minimized. The stabilizing materials used to achieve these parameters are to be determined by the agency that is investigating a specific SFDR project. SFDR is used to correct structural deficiencies in pavement; these deficiencies include deep rutting, load-associated cracks, thermal cracks, reflection cracks, and maintenance patches such as spray, skin, potholes, and deep hot mix. SFDR can correct inconsistencies in the subgrade base as well as the asphalt layers.
