Paving in Desert Conditions with Gilsonite

Desert roads face extreme heat, wind-blown sand and large daily temperature swings.

Challenges

• Pavement temperatures above 70°C
• Rapid binder aging under intense UV
• Dusty aggregates that hinder adhesion

Solutions

• Gilsonite-modified binder for high-temperature stiffness
• Clean aggregates and good filler control
• Proper compaction in the cooler hours of the day

Practical supply

Granular gilsonite is easy to handle in hot, windy plant conditions and reduces dust compared with fine powder.

Results

Gilsonite-modified mixes typically show better rut resistance and less bleeding during hot summers.

Construction tips for desert projects

Binder choice

Gilsonite-modified binder with higher softening point resists softening and rutting under extreme heat.

Maintenance

Seal cracks before sand fills them and prevents sealing.
