ROADWAY DUST CONTROL
Dust control products are applied to aggregate (gravel) roadways when the vehicle traffic account exceeds 200 vehicles per day to inhibit fugitive dust.
When a roadway segment meets the criteria for County mitigation, the County may, when practical and within budgetary constraints, select one (1) of the following alternatives to mitigate dust:
- Surface treatment using dust control agents with a frequency of no more than (2) applications per year at the County’s discretion. Such treatment could be Magnesium Chloride, which is an environmentally-friendly dust control and soil stabilization product. Magnesium chloride is an intermediate solution to reducing dust on low-volume roads.
- Six-inch stabilized aggregate base using dust control agents.
- Paving, Recycled Asphalt Pavement (RAP), or Chip Seal
- Speed limit reduction
- Periodic watering.
