Full-Depth Reclamation (FDR)

Full-depth reclamation (FDR) is a technique in which the full flexible pavement section and a predetermined portion of the underlying materials are uniformly crushed, pulverized, or blended, resulting in a stabilized base course. This fact sheet highlights FDR research and implementation.

Implementation of New Technologies

Throughout MnROAD’s first decade of operation, the facility’s engineers have introduced, developed, and encouraged the use of new technologies and techniques. This fact sheet highlights three technologies: Intelligent Compaction (IC), the Dynamic Cone Penetrometer (DCP), and Ground Penetrating Radar (GPR).

Low-Volume Roads

Low-volume roadways are often unappreciated and under-researched by pavement engineers when held alongside their high-volume interstate and highway counterparts.

But MnROAD, a key element in TERRA's comprehensive road research strategy, has established itself as a national leader in the study of low-volume road research and construction techniques. In fact, no other test track gives researchers the ability to investigate low-volume roads to the extent of MnROAD. Extensive experiments and continuous data collection on test sections of the MnROAD low-volume road (LVR) have produced a number of benefits to Minnesota roadways and to the larger pavement community.
