Asphalt Systems Inc. recently became the first company in its industry to complete a life-cycle assessment for its gilsonite-based GSB-88 asphalt preservation emulsion. Conducted according to International Organization for Standardization (ISO) guidelines and standards, the assessment measures a product's lifetime environmental impact.

As a result, GSB-88 is the first asphalt preservation product to receive an Environmental Product Declaration — an independent assessment of the product's environmental performance. The company says the product could reduce CO2 emissions by 1.2 million metric tons a year and save billions of dollars in paving costs, if used to preserve existing asphalt on a global level.
