Paving in Desert Conditions with Gilsonite
Desert roads face extreme heat, wind-blown sand and large daily temperature swings. Granular gilsonite is easy to handle…
Crushed and screened 1–5 mm gilsonite for asphalt plants, industrial blending and low-dust handling.
Key benefits
- Low dust compared with fine powder
- Free-flowing for automatic feeders
- Fast dissolution in hot mixes
- Consistent size distribution
Product overview
Granular gilsonite is crushed and screened to a controlled 1–5 mm size. It flows well, produces little dust and dissolves quickly in hot bitumen or in the asphalt mixer, which makes it the preferred form for dry-process addition at asphalt plants.
Applications
- Dry-process asphalt modification
- Foundry sand (controlled gas release)
- Industrial blending
- Briquetting
