Environmental Product Declaration for GSB-88, Asphalt Systems, Inc.

Product Information

GSB-88 is an emulsified, gilsonite-modified pavement sealer and rejuvenator. The product rebinds the surface aggregate while sealing and rejuvenating the surface binder, providing a cosmetically enhancing finish. It has been used extensively in both early stage pavement preservation, as well as reactive late stage applications for badly raveled and deteriorated roads, parking areas, and airfield runways and taxiways. It extends the life of asphalt pavements by an average of five years. It is applied with standard asphalt emulsion application equipment, generally asphalt distributors. In some cases it may be advisable to broadcast a very light application of sand over the still wet GSB-88.

The analysis shown here was performed in accordance with the Earthsure Environmental Product Declaration Program, using the product category rule for pavement preservation products. The analysis is based on a life cycle assessment of GSB-88, using data collected from November 2009 to November 2010. Environmental Product Declarations from other sources using different Product Category Rules may not be comparable to this one.
