NOTE:

This guide specification covers the requirements for gilsonite modified asphalt surface coatings (not coal tars products, only GSB-88 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 GSB-88 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).

This specification can be used for high volume or high speed roads, taxiways and runways only with the incorporation of a suitable aggregate in order to maintain adequate surface friction and only with the written approval of the cognizant NAVFAC (Echelon III), AFCEC, MAJCOM or TSMCX Pavement Engineer. At present, only the GSB-88 emulsion, seal coat product with aggregate should be considered for use on airfield runway pavements.

This specification includes requirements for proprietary products that have been demonstrated to the Government to be acceptable for use. The project designer is encouraged to specify generic products to their fullest practical extent. Proprietary products cited herein may be specified with proper justification for use in a contract document, specified as required proprietary products.

If used on Design/Build projects involving high volume or high speed roads or any airfield pavement, this section must be prepared by the Government RFP preparer and must not be further edited by the Contractor's Designer of Record.
