American Gilsonite


High-performance road surfaces have long been made possible with the use of Gilsonite. Gilsonite’s superior properties make it the go-to modifier for hot mix pavements and pavement sealers.

Hot Mix

As an asphalt binder modifier, the unique properties of Gilsonite® make a road that is less susceptible to high-temperature and deformation performance issues. When these modified binders are used in recycled asphalt pavements, Gilsonite adds back what time has taken from the old asphalt, making it easier to use more of this recycled material. The Gilsonite-modified asphalt binder will produce a stronger road that can be thinner by nearly 20 percent compared with other pavements. For more information about this application, please contact us.

As an aggregate modifier, Gilsonite can be added directly at the hot mix plant with no additional equipment. The excellent bonding properties of Gilsonite will produce a high-strength, high-performance pavement that also resists water stripping.

High strength and durability
Superior deformation performance
Reduced pavement thickness
Reduced temperature susceptibility
Increased resistance to water stripping

Gilsonite makes roads stronger to last longer.

Gilsonite modifies asphalt binder and pavement sealers to provide stronger, longer-lasting roads

Pavement Sealers

Gilsonite’s proven properties make high-performance solvent-based and emulsion pavement sealers dry quicker, look better and last longer. Gilsonite is Naturally Better®. As a natural antioxidant, it allows pavement sealers to stay blacker longer. Gilsonite’s unique molecular fractions rejuvenate the pavement being sealed. The strong bonding properties of Gilsonite help weatherproof the sealer.

Making longer-lasting pavement helps the environment. By rejuvenating pavements with recycled asphalt instead of replacing them, there is a proven significant reduction in energy used as well as a reduction in required resources. For further information, please contact us.
