Two primary causes of asphalt deterioration are surface oxidation and moisture damage. GSB-88® is designed to mitigate these impacts by reintroducing essential binders to the pavement matrix, enhancing the structure and adding years of life, while simultaneously sealing the surface to help repel water. The binders also prevent or cure surface raveling, which produces foreign object debris (FOD) that can damage or destroy jet engines. Based on nearly three decades of projects, and studies, the Department of the Navy concluded that the average treatment cycle for GSB-88 is five years. This is considerably longer than coal tar products and much more environmentally friendly as well.
GSB-88® (gilsonite sealer-binder emulsion) is an environmentally friendly restorative sealer for pavements that are in fair to good condition. Economical and versatile, it has been used for pavement preservation since 1988. Axtell’s, Inc. began applying GSB-88® in 2015 and is specialized specifically in Airport applications.
The GSB-88® material is produced by Utah based Asphalt Systems, Inc. This gilsonite-based, environmentally-friendly emulsion product enhances, seals, and extends the life of asphalt at a low cost per square yard. Formulated in 1988, it is applied on pavements ranging from high-speed state highways to parking lots, city streets, county roads, and more than 500 military & civil airport runways – from Alaska to Florida and Maine to California. This product fully meets all Federal P-608 specifications for pavement preservation. Axtell’s, Inc. currently services airports in all states East of the Mississippi.
The GSB-88®/RPS sealer has a proven history of success through wide applications and great tolerance for extreme environmental conditions. Throughout the past decade, the GSB-88®/RPS sealer has been successfully applied on commercial and general aviation runways (grooved and un-grooved), taxiways, and ramps. The sealer’s environmental performance has been tested under all four regions of the U.S.: wet-freeze, dry-freeze, wet-no freeze, and dry-no freeze.
GSB-88® is the only product in the asphalt industry to undergo rigorous independent third-party environmental testing. After an intensive 2011 Life Cycle Assessment by the Institute for Environmental Research & Education (IERE), GSB-88® earned an Environmental Product Declaration (EPD) attesting to the significant environmental benefits of its use in preserving pavement. GSB-88® has also been honored with a GreenCircle®/LEED Certification, recognizing that one application every five years can significantly extend the life of asphalt and help reduce global warming, acidification and eutrophication by nearly 50% when compared to reconstruction.
Benefits of GSB-88®:

GSB-88®® EMULSIFIED SEALER/BINDER
Technical Instructions & Specifications
GSB-88® Emulsified Sealer/Binder is a chemically engineered asphalt preservationproduct comprised of a cationic emulsion with Gilsonite, rejuvenators and specially selected plasticizers. This chemical colloid stabilized emulsion has been specifically formulated for sealing asphalt parking lots, city streets, roads, highways, airport aprons, taxiways, and runways. GSB-88® provides a durable yet flexible seal coat, while special plasticizers and oils penetrate the service binders. The result is an emulsified sealer/binder that restores vital components to asphalt which are lost during the aging and oxidation process, providing a long wearing anti-oxidative seal. GSB-88® also helps to rebind the surface and thereby mitigate raveling issues. It dries to an absolute black color, which beautifies the pavement surface and provides tangible cosmetic benefit. Furthermore, GSB-88® has achieved Green Circle Certification®, which compares the lifespan of a standard asphalt road without GSB-88® treatments and a road with GSB-88® treatments. (Reference: Environmental Product Declaration)

Storage and Handling Instructions
GSB-88® is to be stored in vertical storage tanks and shall be handled like any standard asphalt emulsion. The storage tank should be equipped with a slow revolution mechanical agitator. Hot water heating coils, electrical coils, or electrical heaters are required in colder climates to prevent the emulsion from freezing. Positive displacement gear pumps should be used to transfer and apply GSB-88® materials. Storage and handling temperature are 50°F (10°C) to 160°F (71oC). GSB-88® should be protected from freezing, or whenever outside temperature drops below 40°F (4°C) for prolonged time periods.
Equipment: GSB-88® is to be applied with standard bituminous distributors. The equipment must be in good working order, and contain no contaminants or dilutents in the tank. Spreader bar tips must be clean, free of burrs, and adjusted for regulated flow. Any type of tip or pressure source is suitable that will maintain predetermined flow rates and constant pressure during the application process. The equipment should be tested under pressure for leaks and to insure it is in working order before use. No special mixing equipment is necessary since GSB-88® concentrate may be easily diluted with water in the spreader tank.
Dilution: GSB-88® concentrate must be diluted with water. Water for mixing shall be potable, with a maximum hardness of 90ppm calcium and 15ppm magnesium, and deleterious iron, sulfates, and phosphates maximum 7ppm, and less than 1ppm of organic byproducts. Ideally water shall be softened. Water shall be minimum 140F prior to adding to emulsion and shall be within 10F of emulsion temperature. Emulsion shall be 140F to 180F prior to adding water. Always add the water to the concentrate emulsion, never add concentrate emulsion to the water. Two dilution rates are recommended as follows
1 part GSB-88® to 1 part water for most applications is recommended.
2 parts GSB-88® to 1 part water for use on hills where run off may be of concern, or on very rough surface texture pavements.
Polymer Addition: The polymer shall be a vinyl acrylic polymer approved for use by Asphalt Systems Inc... Consult Asphalt System's Technical Representative for specific details.
Rate of spread is normally determined by the texture, porosity, and age of the asphalt pavement to be sealed. Application rate can vary from 0.08 to 0.15 gallons per square yard (0.36 to 0.68 Liters to Square Meter). For 2:1 dilution, 0.08 to 0.12 gallons per square yard (0.36 to 0.54 Liters to square meter) is recommended. For 1: 1 dilution, 0.10 to 0.15 gallons per square yard (0.46 to 0.68 Liter to square meter) is recommended. Exceeding recommended application rates is not recommended without consulting Asphalt System's Technical Representative.
Cure Time: Expected cure times with proper applications should generally range from 2-4 hours depending upon local climatic conditions (humidity, surface temperature, daytime/ nighttime application, spread rates and dilution, etc). Sheltered or shady areas may require longer cure times.
Application Precautions: GSB-88® is not to be applied to wet or damp pavement surfaces. Do not apply during rainy or damp weather, or when rain is anticipated within 8 hours after application is completed. Pavement surface temperatures should be 50°F (10°C) and rising before application of GSB-88® is applied. At least three hours of daylight should remain after completion of the application. The Emulsion temperature for application should be 130oF, but not exceed 160oF. GSB-88® should not be applied on extremely windy days.
Caution should be taken when applying GSB-88® over existing coal tar treatments, as curing time and traffic readiness could be compromised, consult with Asphalt System's Technical Representative
Preparation of Pavement Surfaces: Repair and patch all major pavement defects. All cracks, other than hairline cracks, should be filled with suitable bituminous crack filler. Scrape all oil spots to remove excess oil and dirt. Just before applying GSB-88® clean the asphalt surface of all loose dust, dirt, and other debris.
Sanding: If needed, sanding should be done at the same time GSB-88® is applied to maintain adequate surface friction. A hard, highly fractured sand should be used. Because there are regional differences in sand characteristics, a knowledgeable local pavement maintenance engineer should be consulted to insure that the appropriate amount and type of sand is chosen to regain any lost skid resistance. Sanding is best done by mounting a sand slinger on the applicator and applying approximately 0.10 to 0.5 pounds of sand per square yard to achieve needed friction results. Consult Asphalt System's Technical Representative for specific details.
Striping: Striping should be done in two phases, the first phase is to be a 30% stripe after the GSB-88® has had sufficient time to cure. Final Striping should be done 30 days after the final application.
Maintenance: Under normal traffic conditions a single application of GSB-88® when properly applied, should not require reapplication for 3 to 5 years. Thereafter, additional applications of GSB-88 can be reapplied to extend the life of the pavement indefinitely.
Health and Safety: Consult the Safety Data Sheet (SDS) for GSB-88® fire and explosion data, health hazard data, first aid procedures, reactivity data, spill or leak procedures, waste disposal and use of personal protective equipment.
