Dust Control

Dust control products are applied to gravel roadways when the vehicle traffic count exceeds 150 vehicles per day. These products may be applied when there is a residence within 500 feet of these roadways.

Boulder County Road Maintenance uses RoadSaver for dust control:

  • RoadSaver is a high-purity grad of Magnesium Chloride used as a dust control and road stabilization agent. It is a hygroscopic compound that attracts moisture from the air and resists evaporation. RoadSaver binds fine dust and aggregate (gravel) to keep surfaces stable and dust free. It can be applied to:
    • City, county, and designated haul roads
    • Construction areas

During the warmer months, we use water on gravel roads, which helps compact the surface. Tankers that place water are labeled with as carrying “non-potable water.” During winter months, several tankers apply a de-icer to paved roads. The material tends to leave a film on vehicles, but this is easily removed with a soap and water wash. It is recommended that you wash your vehicle frequently during winter months due to de-icers and salts used during icy conditions.
