Full-Depth Reclamation (FDR) Case Histories
When it became clear that Tyrone, Georgia's main street needed a complete restoration, city officials turned to full-depth reclamation for the job.
Change to the depth of surface asphalt for a roadway in Thomas County, Georgia, would have cost more than $1 million. PCA-SE worked with the county to redesign the project and increase the FDR depth to 10 inches, relieving the need an additional inch of asphalt and saving the county more than $1 million.
Selfridge Road in Moreau, New York, encountered a myriad of problems throughout the years with numerous complaints of ride quality until a New York transportation decision makers attended a PCA Northeast Region FDR informational lunch and seminar last March.
The rebirth of Fort Worth, Texas' La Gran Plaza is a place that has realized FDR’s true value in the rehabilitation of its parking lot. The resulting reclaimed base using FDR enabled the owners to benefit from a reduced construction time and cost savings while providing the proven long-term performance of a cement-stabilized base.
The South Carolina DOT has been using FDR with cement for over 10 years with excellent results, and the Dennis Corporation thought the same procedure could be used on the county’s gravel roads.
Full-depth reclamation (FDR) with portland cement was the clear choice in the rehabilitation of a 15,000 square yard parking area at the Hanes Mall of Winston Salem, North Carolina. In need of a facelift, the parking area of JCPenney underwent a transformation just in time for the holiday season.
As counties are expanding at an exponential rate, they are faced with maintaining more roads with shrinking maintenance funding and increased roadwork costs. Coweta County in Georgia is overcoming this by implementing full-depth reclamation (FDR) with portland cement.
The Friedman Memorial Airport in Hailey, Idaho selected “full-depth reclamation” with portland cement to meet a master plan objective and economically re-open for traffic in the shortest possible time span and cut costs over $1 million.

For Terminal 115, FDR was found to be the most cost efficient solution—especially when working through Seattle, Washington's naturally wet environment.
In 2005, Elmore County, Alabama, began experimenting with full-depth reclamation (FDR) to meet its growing need to address base failures on a maintenance level rather than by rehabilitating long stretches of roadway.
"They’ve not done any re-work on any of the bases that we’ve [cement] stabilized,” says Sanford LaHue Jr, consulting engineer, Schrickel, Rollins and Associates, Arlington, Texas.
Recognized as a cost-effective method to rehabilitate failed flexible pavements, full-depth reclamation (FDR) with portland cement provides an extremely durable material in a sustainable manner. Its benefits convinced the City of Dallas to embrace the use of FDR in the restoration of many streets.
Case study of a failed city street that was reconstructed using full-depth reclamation (FDR) with cement for the base, and surfaced with ultra-thin whitetopping (UTW).
A 1.7-mile stretch of Franklin County Highway 84 just north of Cedar Lake, Alabama, became the first known FDR project in the state incorporating portland cement.
When a 4.4 mile section of Virginia State Route 30 near Mechanicsville became worn out due to high volumes of heavy truck loading and stripping of lower layers, the Virginia Department of Transportation turned to full-depth reclamation (FDR) with portland cement to create a new durable base.
Old Natchez Trace, a 4.2 mile stretch of highway in Tennessee, is rehabilitated with full-depth reclamation with cement.
Michael Baker International, LLC in Raleigh, North Carolina, upgraded and reconstructed the Raleigh Executive Jetport The project increased the runway’s weight capacity from 80,000 to 100,000 pounds.
When flyash didn't meet the rehabilitation project's compressive strength requirements, cement was chosen as a cost-effective stabilizer.
U.S. Route 60 is the main thoroughfare into and out of Powhatan, Virginia. When a 1.8 mile asphalt section of this heavily used facility was in need of major repair due to structural distress, the Virginia Department of Transportation (VDOT) chose full-depth reclamation (FDR) with cement for rehabilitation.
“…we were able to reduce the asphalt section by 1 to 3 inches and saved another $1 million over and above the savings already realized by FDR.”
A severely deteriorated 30-mile section of the Natchez Trace Parkway southwest of Jackson, Mississippi was recently rehabilitated through a process known as Full-Depth Reclamation (FDR).
They are programming the FDR work in order to build routes of cement stabilized all-weather roads that will not have to undergo spring load restrictions.
Kalia Road is one of the most heavily used roadways in the entire state of Hawaii. The pavement in this area had experienced shoving (serious rutting) and had created serious liability concerns for the owners. Engineers chose to correct the base failure through full-depth reclamation (FDR) and then complete the roadway with a ultra-thin whitetopping (UTW) surfacing.
