Gilsonite Sealers for Airport Pavements
Translate this article:

Airports use surface treatments to extend asphalt life and resist fuel spills.
Benefits
- Restores binder at the surface
- Improves resistance to oxidation
- Helps resist fuel and oil
Considerations
Friction must be maintained; follow aviation authority guidance.

Special airport requirements
- Skid resistance must stay within limits
- Markings must remain visible
- Fuel and hydraulic fluid spills are common
- Foreign object debris (FOD) must be avoided
Uses of gilsonite sealers
Gilsonite-based sealers and rejuvenators have been used on taxiways, aprons and runway shoulders to restore surface binder and slow oxidation.
Practical notes
- Follow the airport authority’s specifications and friction testing requirements.
- Apply during low-traffic windows with careful coordination.
- Add fine sand where friction needs to be maintained.
Benefits
Extends pavement life, reduces ravelling and FOD, and restores a uniform appearance.
