“To get the most bang for the buck for taxpayers, Caltrans targets dollars where they are most effective — pavement preservation,” says Caltrans Director Malcolm Dougherty.


“Every $1 spent on preventive pavement maintenance saves Californians $11 that would have been spent on expensive pavement repairs.”

GSB-88 ® penetrates into the pavement matrix and becomes part of the surface of asphalt, and is sensitive to our delicate environment.

We wanted to try something besides the ss1h asphalt emulsions we had used in the past to keep aggregates bound in place on the shoulders, prevent raveling, and keep newly placed asphalt in a "like new" condition. In 2002 we tried GSB-88 ®. Years later aggregates were still bound tightly in place on our shoulder project and in the new asphalt pavements that were treated...GSB-88 ® was applied to asphalt overlay projects having ADT (average daily traffic) ranging from 300 to 2600 vehicles. Our plans are to continue using GSB-88 ® for our fog seal asphalt preservation applications.
