Cold Seal Coat
Allied Blacktop is the exclusive provider of the GSB-Gilsonite™ rejuvenating sealer and binder. GSB is a penetrating sealer that extends the life of the asphalt.
Our Sweeping Equipment: Elgin Pelican pick-up style broom, Roscoe Straight broom, Billy Goat blowers, and push brooms.
Our Sealcoat Process: Allied crews sweep, scrub, and blow the asphalt surface to maximize the sealer’s coverage and penetration. Then, they apply the sealer. A wand attached to a smaller tanker provides precise and accurate coverage for edges and tight corners. Mack Bearcat distributors equipped with computerized rate control spray the Gilsonite in open areas.
Cold Seal Coat Drying Time:
- Day applications with low humidity and sun: 15 minutes
- Night applications: 30 minutes
Black Diamond Silica Sand may be applied at the specified rate to add structure to the seal coat and provide traction.
Rejuvenating sealers are designed to penetrate the asphalt surface and integrate with the existing asphalt binder oil to retard the oxidation process. Rejuvenating sealers should be applied every 2 to 3 years.
Gilsonite is one of the few petroleum-based cold seal coat applications. It is a petroleum-based ore mine on the West Coast. Gilsonite is extracted, combined with Naphtha, and installed on the asphalt surface.
Allied Blacktop Company performs this application nationwide. It is the premier application for malls, shopping centers, and retail stores.
