What's so great about GSB-88?


All seal coats are not the same!

During thermal expansion and contraction cycles GSB-88 expands and moves at the same rate as asphalt pavement because Gilsonite IS asphalt cement! GSB-88 retains EVERY vital component; polar compounds, maltenes and asphaltenes.

While modern highly refined "fractioned" binders may meet specifications, because vital components have been removed, they experience more rapid oxidation and degradation! Preserving pavement flexibility with GSB-88 improves the performance of an asphalt pavement by extending the time of load carrying ability and places GSB-88 in the forefront as a performance treatment for all pavement types including streets, roadways, highways, airport runways, and all types of commercial pavements.
