New FAA Pavement Design Software

FAA Rigid and Flexible Iterative Elastic Layered Design, known as FAArfield, is a new software package for airport pavement thickness design. As part of the Federal Aviation Administration's transition to computer-based design procedures, FAArfield offers advanced structural and failure prediction models designed to significantly save costs and provide more accurate life predictions for pavement. The author discusses in detail the development and benefits of the new software package, which is scheduled for release in early 2008. Accompanying the software release is the FAA revision of its Advisory Circular (AC) covering Airport Pavement Design and Evaluation. Known as AC 150/5320-6D, the AC revision effectively establishes FAArfield as the standard design procedure. Another new computer program discussed is COMFAA, which is designed to support the FAA’s updated guidance for the reporting of airport pavement strength ( known as AC 150/5335-5A). Other FAA pavement software programs discussed include BAKFAA (Backcalculation – FAA, used in a pavement evaluation program), LEAF (Layered Elastic Analysis – FAA, a structural analysis program), and PROFAA (Profile – FAA, used to compute roughness indices derived from elevation profile data).
