As temperatures drop, sodium chloride loses its deicing power. Depending on conditions, adding more salt to a roadway may be ineffective and wasteful.
To help maintenance managers make the most of their stockpiles and keep roads clear, this Clear Roads research project investigated how salt behaves at different temperatures and concentrations. With a new tool and other educational materials from Clear Roads, practitioners can better understand how and when to apply sodium chloride for best results.
