Calcium chloride is an effective dust suppressant agent when applied to unpaved roads. In addition to the negative health and environmental effects resulting from dusty roads, the loss of fine road particles leads to the loss of larger aggregate. Large aggregate loss results in potholes and a general breakdown of the road surface. Calcium chloride has the unique ability to pull moisture from the air thereby creating a damp road surface. As part of a regular maintenance program, calcium chloride can help create longer lasting, safer unpaved roads.
