ASI’s GSB-88® Sealer/Binder receives GreenCircle recertification

GSB-88® Sealer/Binder Emulsion from Salt Lake City, Utah-based Asphalt Systems, Inc.® (ASI) has been awarded the GreenCircle Certificate for its fourth consecutive year. GSB-88® is the only asphalt emulsion in the world to receive this environmental certification for sustainable pavement preservation excellence. GreenCircle is an internationally recognized third-party certification entity whose thorough evaluation process provides independent verification that sustainability claims related to an organization’s products and operations are honest, valid, and verified. In 2017, GreenCircle’s testing has determined once again that Gilson-based GSB-88® sealer/binder/rejuvenator emulsion is an economical, versatile, and environmentally friendly solution for improving and extending the lifespan of asphalt surfaces. One application of GSB-88® every five years can significantly extend the life of asphalt and help reduce global warming, when compared to reconstruction.

Gilsonite is a unique, naturally occurring resinous asphalt ore found in Utah that does not have to undergo an oil refining process. Gilsonite emulsions are non-flammable, non-carcinogenic and non-toxic. With very low VOC levels, ASI’s gilsonite-based asphalt preservation products are safe for the environment. As an aid to maintaining infrastructure, pavement preservation is both eco-friendly and socially responsible.

ASI products are used by contractors, cities, counties, state government agencies, the civil aviation industry and military customers throughout the United States and abroad. For more information about ASI, please call 801-972-2757, email or visit
