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 Gilsonite-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. In fact, when comparing the lifespan of a standard asphalt road without GSB-88 treatments and a road with GSB-88 treatments, the road with GSB-88 will reduce global warming 49.15 percent, reduce acidification 48.44 percent, reduce eutrophication 49.30 percent, reduce ecotoxicity 35.63 percent and reduce smog 49.38 percent.
