The use of liquid calcium chloride on unpaved roads as a dust control agent and as a base stabilization material is examined. In thefirst section, a description is provided of how calcium chloride controls dust and the benefits it produces. The performance of calciumchloride is compared with that of other commonly used dust control agents. Recommended guidelines and application rates for controllingdust on unpaved roads with calcium chloride are then given. The second section provides a description of how calcium chloride stabilizes unpaved road bases and lists the seven ways the chemical helps build stronger roads. Recommended guidelines and application rates for stabilizing road bases with calcium chloride are provided.
