The Federal Aviation Association (FAA) Airport Concrete Pavement Technology Program (ACPTP) released the Request for Proposal (RFP) for Alkali-Silica Reaction (ASR) Research:
The FAA-ACPTP has issued a RFP for Mitigating Potential ASR Expansion in Airfield Concrete Pavements. This FAA program, currently administered by the National Concrete Pavement Technology Center (CPTech), was secured by American Concrete Pavement Association (ACPA), Portland Cement Association (PCA), and National Asphalt Pavement Association (NAPA) in the FAA Reauthorization Act of 2018. Those who have an interest in submitting proposals are encouraged to do so!

New Advisory Circular (AC): “Airport Pavement Design & Evaluation”:
The office of AAS-100, Office of Airport Safety & Standards – Airport Engineering Division–FAA has released a new AC: 150/5320-6G – “Airport Pavement Design and Evaluation“. This circular is expected to be a significant improvement to the older FAA design circular. While it is not expected to have much of an impact on pavement thickness directly, it is anticipated some improvement in the design details and the software will include user-friendly improvements. It provides guidance to the public on the design and evaluation of pavements used by aircraft at civil airports. Gary Mitchell, Airport Director-ACPA, ACPA‘s Airport Task Force (ATF) provided a review and input.
The branches involved in this are “Design and Construction” and “Data and Airspace“. The mission of the Airport Engineering Division is to carry out the responsibility for engineering standards and research for design, equipment, and airfield development at civil airports. It is also responsible for airport data, safety-related airport airspace issues, and facilitating innovative methods of improving airport infrastructure.
For reporting of pavement strength, the AC titled “150/5335-5C – Standardized Method of Reporting Airport Pavement Strength” – “PCN AC 150/5335-5, Standardized Method of Reporting Airport Pavement Strength – PCR” provides guidance for using the standardized International Civil Aviation Organization (ICAO) method, called the Aircraft Classification Number – Pavement Classification Number (ACN-PCN) method, to report:
• Airport runway
• Airport taxiway
• Airport apron pavement strength
• Instructions for using the COMFAA program to calculate ACN values to determine PCN
