What is P-601 Fuel-Resistant Hot Mix Asphalt (HMA) Pavement?
For more than a century, asphalt pavements have improved incrementally with the introduction of new methods and technologies. Most notably, these include the Hveem Mix Design in the 1920’s, the Marshall Mix Design in the 1930’s, the introduction of rejuvenators in the 1960’s, and the development of Superpave technology in the 1990’s. The Superpave technology was developed to design asphalt pavements based on environmental conditions and traffic. The technology established a system (i.e. “performance grades” or “PG”) for asphalt binders based on their ability to perform under a range of temperatures. The addition of polymers to the asphalt binder was proven to improve the pavement’s resistance to rutting, fatigue and cracking at higher temperatures.
On July 21, 2014, the FAA issued Technical Specification P-601 Fuel-Resistant Hot Mix Asphalt (HMA) Pavement as part of Advisory Circular 150/5300-10G. This specification utilizes a high-polymer asphalt binder, PG82-22 (or better), that not only provides a long-lasting, rut-resistance pavement, but also provides fuel-resistance. With applications at three airports in Florida to date, this stiffer mix has demonstrated the workability required to ensure a strong, dense asphalt pavement which requires less maintenance and improves the pavement life.

Presenter: Lee Lewis, Principal & Regional Manager, AVCON Engineers & Planners
Lee Lewis is a Principal & Regional Manager with AVCON Engineers & Planners, an airport consulting firm in the southeast. AVCON is in their 27th year of airport planning and design, offering expertise in airfield lighting & NAVAIDs as well as airfield pavements. Lee was born and raised in Naples before graduating with a degree in civil engineering from the University of Florida. He joined AVCON in 1991. In 1998, he opened AVCON’s office in Northwest Florida where he continues to manage numerous airfield projects on commercial service, general aviation, and military airports.
In 2011, Lee managed a revolutionary apron rehabilitation project at Bob Sikes Airport (CEW) in Crestview that was the first to apply a new non-proprietary asphalt specification. This award-winning project was funded by the state of Florida and resulted in a low-maintenance, fuel-resistant, long-lasting asphalt pavement that has been referred to as “the future of airport pavement.”
FAA recognized the benefits of this asphalt technology and released “P-601 Fuel-Resistant Hot Mix Asphalt (HMA) Pavement” as a new airport standard on July 21, 2014 as part of Advisory Circular 150/5300-10G. This asphalt specification was successfully installed in a terminal apron expansion project at Northwest Florida Beaches International Airport last May, the first FAA-funded project using the P-601 technology at a commercial-service airport. The airport’s FBO (Sheltair) is currently initiating an apron expansion project that will apply this same asphalt technology.
Representatives from the U.S. Army Corps of Engineers, the U.S. Navy, and the U.S. Air Force are collectively evaluating the formal adoption of this specification as a new military standard.
