ACC Online Learning
Associated Asphalt is a full-service asphalt supplier to the asphalt paving industry with an extensive product line. Founded in 1948 and headquartered in Roanoke, VA, Associated Asphalt is the largest asphalt supplier in the eastern United States with 34 asphalt terminals. Associated Asphalt has a complete line of specialty asphalt products, including the StellarFlex® line of polymer-modified asphalts, the FlexGard® high performance overlay mix system, J-Band® - a Void Reducing Asphalt Membrane (VRAM) for longitudinal joints, and ready-to-use warm mix asphalt binders. StellarFlex® polymer-modified binders are specifically formulated to solve challenging pavement applications – StellarFlex® SP for heavy-duty pavements, StellarFlex® BD for bridge deck pavements, StellarFlex® CR for mitigating reflective cracking, and StellarFlex FR® for fuel resistant asphalt pavements.
StellarFlex FR® is a highly polymer-modified asphalt formulated to resist damage from jet fuel spills and de-icing chemicals when used in an FAA P-404 mix. . The polymer modification not only provides fuel resistance, it also provides excellent resistance to rutting and cracking, which results in improved durability and increased pavement life. StellarFlex FR® meets all requirements for the FAA “P-404 Fuel Resistant Asphalt Mix” specification. The product was first placed in 2002 on a taxiway at LaGuardia Airport, and has been used on airfield pavements at both large commercial and general aviation airports across the United States over the past eighteen years. P-404 mixes containing StellarFlex FR® binder have demonstrated outstanding durability and long life in all applications to date.
Associated Asphalt distinguishes itself from typical asphalt suppliers with experienced technical and marketing groups that have developed specialty products such as StellarFlex® FR and provides field support to ensure successful installation.
ACC Lunch and Learn On-Demand Webinar - Development and Performance History of the FAA P-404 Fuel-Resistant Asphalt Mix Specification
This complimentary ACC on-demand Lunch & Learn webinar - generously sponsored by Associated Asphalt Pavement, LLC - will provide an overview of the development of the FAA P-404 Fuel-Resistant Mix specification. Jet fuel, hydraulic oil and de-icing chemicals cause damage to asphalt pavement on airfields. Coal tar sealers have been used to protect airfield pavements from fuel damage, but they are carcinogenic.
Associated Asphalt developed an environmentally friendly, highly polymer-modified asphalt binder that makes the asphalt pavement resistant to fuel and oil spills and eliminates the need for hazardous sealers. This presentation will document the history of use of fuel-resistant binder beginning at La Guardia Airport in 2002. It will describe the development of a generic fuel-resistant mix specification that is a modified version of the P-401 specification. The P-401 mix specification was modified to optimize the properties of a highly-polymer modified liquid asphalt and produce a mix that is highly resistant to rutting and cracking, as well as resistant to damage from jet fuel, hydraulic oil and de-icing chemicals. The result is a fuel-resistant mix that will last significantly longer than a P-401 mix.
This specification was first used at Logan Airport in 2004. The FAA adopted the Logan Airport fuel-resistant mix specification in 2014, after evaluating the performance over a ten-year period. This program will include extensive laboratory testing documenting the superiority of the P-404 mix and a field performance history dating back to 2002. The webinar will provide participants the knowledge necessary to select P-404 mix for appropriate airfield pavement applications.
At the end of this ACC on-demand Lunch & Learn webinar, participants will be able to:
• Recognize the dangers associated with the use of coal tar sealers.
• Compare P-401 mix design criteria with P-404 mix design criteria.
• Assess the mix performance testing data of P-404 mixes.
• Apply the information presented to correctly specify P-404 pavements.
