What is Full-Depth Reclamation?

Full-Depth Reclamation (FDR) with cement is a type of Soil-Cement and pavement rehabilitation method that involves recycling an existing deteriorated asphalt surface and its underlying base, subbase, and/or subgrade materials into a new stabilized base layer.  The FDR process consists of the in-place pulverization of the existing roadway materials, applying and uniformly blending in portland cement and water, compacting with rollers, shaping with motor graders, and proper curing.  The result is a stiff, stabilized base layer that is ready for a new bituminous or concrete surface course.  FDR with cement saves money and reduces the carbon footprint of roadway construction projects by reducing mining, hauling, and disposal of basic construction materials.

Recycling Saves Money and Natural Resources

Full-depth reclamation uses the materials from the deteriorated asphalt pavement, and, with the addition of cement, creates a new stabilized base.

A surface consisting of a thin bituminous chip seal, hot-mix asphalt, or concrete completes the road. The recycled base will be stronger, more uniform, and more moisture resistant than the original base, resulting in a long, low-maintenance life. And most important, recycling costs are normally at least 25 to 50 percent less than the removal and replacement of the old pavement.    

Material Conservation: A Wise Choice

Conserving construction materials through recycling with cement makes smart economic and strategic sense. A century of modern growth and urbanization in America has depleted once plentiful aggregate supplies. Frequently, aggregates either come from distant quarries at great expense or from local sources offering only marginal quality. Continuing to exhaust these valuable resources to rebuild existing roads only propagates and accelerates the problem.
