ASCE Conference

The American Society of Civil Engineers’ Transportation & Development Institute (ASCE T&DI) hosted their International Airfield & Highway Pavement Conference in Austin, Texas on June 14-16, 2023. Representatives from FAA’s Airport Research & Development Branch (ATR) - Dr. David Brill, Dr. Navneet Garg, Dr. Richard Ji, and Dr. Dan Offenbacker – attended the conference and shared key FAA updates.

Presentations & Workshop Facilitation

Dr. Brill and Dr. Garg, along with Dr. Offenbacker facilitated the 8-hour workshop Airport Pavement Design and Evaluation – Introduction to FAARFIELD 2.0 and ICAO’s ACR-PCR (Aircraft Classification Rating-Pavement Classification Rating) System. FAARFIELD 2.0 (FAA Rigid and Flexible Iterative Elastic Layered Design) uses the global standard ACR-PCR method and is the FAA’s definitive software for airport pavement thickness design, evaluation, and pavement strength reporting.

The workshop spotlights FAA’s role as a global leader in aviation safety and efficiency. Thirty-eight individuals from six countries attended, including consulting engineers, representatives of government and military organizations, and academia.

In addition to the workshop, Dr. Brill delivered the presentation PCN-PCR Comparisons for Large and Medium-Hub Airport Runways and moderated the technical session Airfields – Materials, Modeling, & Design. Dr. Garg presented the session FAA Research Efforts to Address Sustainability at Airport Pavements and was a panelist in the Pavements Opening Plenary Session along with members from the Federal Highway Administration, Texas DOT, and academia.
