Why does FDR matter to FedEx?

A unique process for reconstructing pavement that’s:‐ More durable‐ Less expensive‐ Faster‐ Less disruptive

FedEx Ground has many yards past their design lifeChallenged with reconstructing vital part of the facility without impeding operations

Definition of Full‐Depth Reclamation (FDR)

Method of flexible pavement reconstruction that utilizes the existing asphalt, base, and subgrade material to produce a new stabilized base course for an asphalt, chip seal, or concrete wearing surface.

A new cement recycled base will be stronger, more uniform, and more moisture resistant than the original base, resulting in a long, low‐maintenance life

Advantages of the FDR processUse in‐place materials 

‐ Saves money‐ Conserve virgin material‐ Saves energy by reducing mining and hauling

Limits hauling of materials from site‐ Saves fuel and reduces traffic

Maintains existing grade and restores the cross section‐ Meet existing structures

Advantages of the FDR process

Reliably treats all types of pavement distress‐ Versatile and robust

Reduce construction time Increases the load‐carrying capability of the pavementReduces the environmental sensitivity of the pavement

When is FDR appropriate?

Distress indicates the pavement distress is in the base or subgradeFull‐depth patching is required on more than 15 to 20 percent of the total surface areaPavement structure is inadequate for current or expected future traffic.

Traditional Pavement Reconstruction Challenges

Huge impacts to Hub traffic‐ Required to shut down areas for at least a week‐main drives, dock doors, etc‐ Work area not open to traffic during process‐ Impacts on hub efficiency and lost profitability for FXG

Budget‐Nearly $10,000,000 Expected Costs Schedule‐Expected duration of 7‐8 Months Large potential for undercut change orders, delays Reconstruction susceptible to weather delays‐wet base Safety‐deep excavations within yard to protect

32

Page 33: Stan Bland, PE (SC) Pavement Applications Director ......Piedmont Triad International, NC aprons 20. Elizabeth City, NC. Elizabeth City, NC. Elizabeth City, NC. Parking lots Retail

Decision for FDR:

Reduced impact to Hub:‐ Work areas shut down only a day at a time, opened back up‐ No long shut down of docks, lanes, etc‐ Provides suitable drive surface even during construction process‐ Substantially less construction vehicle traffic on site

Budget‐ $4,000,000. $6,000,000 savings, not accounting for savings on hub efficiency. Schedule‐4 months. Nearly a 50% decrease vs Traditional Much less potential for weather delays. Superior long‐term product Able to regrade poor drainage areas with little effort Less potential for undercut change orders

‐ Entire project completed without any undercut change orders.
