scope:

NOTE: This guide specification covers the requirements for gilsonite modified asphalt surface coatings (not coal tars products, only Gilsonite modified asphalt emulsion sea coats with a bituminous base residue containing no less than 20 percent Uintaite or Gilsonite, here after referred to as Gilsonite modified asphalt emulsion.) for low volume roads, parking areas, airfield secondary and tertiary pavements (low-speed taxiways, shoulders, overruns), and other general applications with or without aggregate applied on the applied coating. An asphalt seal coat without aggregate, more commonly called a 'fog seal", can be considered for use on pavements with low to moderate weathered surfaces (as defined by ASTM D5340). The use of Gilsonite modified asphalt emulsion should be used whenever possible. The use of this product on a runway must be approved by cognizant NAVFAC (Echelon III), AFCEC, MAJCOM or TSMCX Pavement Engineer).
