Yes, you can use calcium chloride for dust control. Calcium chloride helps keep roads moist to trap in dirt and dust while keeping it heavy enough to remain on the ground instead of being kicked up by the wind.
Calcium chloride absorbs water and does not evaporate quickly in high temperatures like water does. The solution also connects to heavier, negatively charged particles, such as clay and sod, to hold dust down on the ground. When used on unpaved roads, calcium chloride minimizes the amount of gravel needed to reduce dust. The solution also maintains the condition of the roads much better than other options such as oil while costing less than other forms of road treatments.
