Advanced Airport Pavement Advanced Airport Pavement Design Project BenefitsDesign Project Benefits
Potential capital costs avoided.– Avoid restricting loads of air carriers.– Avoid unnecessary strengthening of existing
pavements and structures.– Avoid cost of delays.
$1.7 billion of capital costs avoided over the next several years.

Pavement Software ProductsPavement Software Products2006 FAARFIELD FAA Rigid and Flexible Interactive Elastic Layer Design: Fully tested
design procedures incorporating 3D Finite Element responses for rigid..
2003 FEDFAA Beta design program incorporates 3D Finite Element response model for rigid pavement, LEAF for flexible pavement.
2003 FEAFAA 3D Finite Element analysis of rigid pavements, runs on desktop PC.
2003 LEDFAA version 1.3
32-bit program uses LEAF for layered elastic analysis. Updated aircraft library includes A380. Incorporated in AC 150/5320-6D, Change 3.
2002 BACKFAA Backcalculation of elastic properties using LEAF. Also used for LEAF development.
2002 COMFAA Computes pavement strength and thickness by ACN and FAA methods.
2001 LEAF Layered Elastic Analysis – FAA: Layered elastic analysis program for 32-bit Windows, replaces JULEA.
1995 LEDFAA version 1.2
Layered Elastic Design – FAA: Pavement design program for Windows, uses JULEA for layered elastic analysis. Part of AC 150/5320-16 (Pavement Design for B-777). Program and AC cancelled April 30, 2004.
All programs for use on desktop PCs

Final ReportDOT/FAA/AR-04/46 Office of Aviation Research Washington, D.C. 20591 December 2004
Operational Life of Airport Pavements
“… airport pavements designed following AC 150/4320-6D have sufficient thickness to provide
a 20-year structural life.”

Report has been prepared and submitted for consideration by the ICAO ACN Study Group.
Pavement Design WorkshopsPavement Design Workshops(FEDFAA Beta / LEDFAA 1.3)(FEDFAA Beta / LEDFAA 1.3)
Four pavement design workshops in 2004:– Tokyo, Japan (May 2004)– Denver, CO (June 22)– Arlington, VA (July 29).– Beijing, China (Sept. 27-29)
Covered updates to LEDFAA 1.3 software.Introduced FEDFAA Beta.Additional workshops planned in 2005-06.
FEDFAA Beta ReleaseFEDFAA Beta Release Evaluation version of FEDFAA posted on
the AAR-410 web site September 2003. FEDFAA 1.3 Beta posted September 8,
2004. http://www.airporttech.tc.faa.gov. The beta release demonstrates all planned
functionality of the new program. Beta design thicknesses are preliminary.
– Version 1.3 gives thicknesses approximately the same to thinner as existing design procedures.
