Deteriorating pavement is a constant problem for roads, parking lots and airports. To help our clients, SME’s pavement experts turn to a process called full-depth reclamation (FDR).

FDR rebuilds worn out asphalt pavements with a new and stronger foundation, and saves money by recycling the existing materials. FDR eliminates excavation and replacement with new materials to expedite construction time and reduce costs. The old asphalt and base materials are pulverized, mixed with cement and water or/or other chemical agents, and compacted to produce a strong, durable base for either an asphalt or concrete surface.


Sampling and laboratory pre-testing is critical to provide a satisfactory mix design that will provide a stable and functioning newly developed subbase course as expected.

Quality Control

The success of an FDR project depends upon the careful attention to the quality control factors including adequate pulverization, proper cement content, proper moisture content, adequate density and adequate curing.

Mix Design

Material samples from the site should be pulverized in the lab to create an aggregate-soil mix that will be similar to that expected from the FDR process. The mix design procedure is the same as that performed for soil-cement.
