The recently published Federal Aviation Administration's revised Advisory Circular contains new and revised "P" Specs. One of the new additions is P-608 Emulsified Asphalt Seal Coat, which calls for Gilsonite Modified Asphalt Emulsion to be used on all airfield pavements, including runways and high-speed taxiways. Although P-608 is a new FAA specification, Gilsonite Modified Asphalt Emulsions have been used as highly effective airfield pavement preservation tools for over 40 years.
