Cuts Road Maintenance Expense Solvay Calcium Chloride is a clean white chemical salt. It dissolves readily when exposed to air. It is odorless, colorless, and without effect on rubber. Easily applied. When applied to a road it soon becomes incorporated with the top course and absorbs sufficient moisture from the air to lay the dust and keep the surface smooth and compact. Saving the surface saves the entire road-bed.
