Description/Instructions Date
AIRPORT PAVEMENT DESIGN
Flexible Pavement Design (MS Excel) Flexible Pavement Design Manual (PDF) (Updated 7/16/2002) Updated 10/31/2005
Rigid Pavement Design (MS Excel) Rigid Pavement Design Manual (PDF) (Updated 7/16/2002) Updated 4/30/2004
Layered Elastic Pavement Design Version 1.3 (ZIP) Layered elastic design software discussed in Chapter 7 of AC 150/5320-6, Airport Pavement Design and Evaluation. Software updated in June 2004 to include new commercial aircraft models and many general aviation aircraft. Updated 7/26/2004
FAARFIELD 1.302 (3/20/2009) FAARFIELD 1.302 replaced the previous version that accompanied Draft AC 150/5320-6E. The FAARFIELD program became the FAA standard for airfield pavement design upon publication of AC 150/5320-6E, which required the use of the FAARFIELD program.  
COMFAA 2.0
(You will need to scroll down on linked page to view software and related guidance.)
COMFAA, as introduced in version A of AC 150/5335-5, is capable of calculating Aircraft Classifications Numbers in accordance with the International Civil Aviation Organization (ICAO) procedure.  
COMFAA 3.0 (Updated 3/2/2012)
(You will need to scroll down on linked page to view software and related guidance.)

COMFAA 3.0, as introduced in version B of AC 150/5335-5, is the recommended method to determine airport runway, taxiway, and apron pavement strength with the Aircraft Classification Number - Pavement Classification Number (ACN-PCN) method. The software is capable of calculating Aircraft Classifications Numbers in accordance with the International Civil Aviation Organization (ICAO) procedure.

Support Spreadsheet for COMFAA 3.0 (MS Excel, 1.78 MB) (Updated 3/2/2012)
Facilitates flexible and rigid pavement information required in COMFAA 3.0 for PCN calculations.

PAY REDUCTIONS FOR AIRPORT PAVEMENT PROJECTS
(AC 150/5370-10, Standards for Specifying Construction of Airports)
Asphaltic Concrete - Payment Adjustment for Densities and Air Voids, Item P-401 (MS Excel) The pay equations in this spreadsheet are consistent with the percent within specification limits (PWL) based pay adjusments in Item P-401 as published in versions B and higher of AC 150/5370-10 but are not valid for previous versions of Item P-401. Updated 2/4/2008
Asphaltic Concrete - Payment Adjustment for Densities and Air Voids, Item P-401SP (MS Excel) This spreadsheet is consistent with Item P-401SP as published in Engineering Brief #59A. Updated 3/30/2007
PCC Pavement - Payment Factor for Strength and Thickness, Item P-501 (MS Excel)

The pay equations in this spreadsheet are valid for versions of Item P-501 published in versions C and higher of AC 150/5370-10.

*Update fixes spreadsheet error that occurred when number of lots exceeded 102.
