The Deicing Salt (Sodium Chloride) shall be Rock Salt #1-medium CC obtained by evaporation of sea water. Sodium Chloride shall be in the form of Rock Salt containing at time of delivery no more than 1.0 percent moisture when dried at 221ºF (105ºC) to constant weight. Sodium Chloride (DEICING SALT), when dried to constant weight as specified above, shall conform to the following requirements: Sodium Chloride (NaCl), minimum percent 97.0; Solubility in boiling distilled water, minimum percent 99.0; It is the intent of this specification to describe a mixture of Sodium Chloride Type "A" crushed rock salt treated with Liquid Magnesium Chloride/Patent #4,676,918 or County of Ocean approved equivalent. The liquid treatment is intended to enhance the performance of the regular rock salt over untreated salt by reducing corrosiveness, improving low temperature performance, reducing bounce and scatter, preventing clumping, salt pile freezing and enhancing flow ability. The treated salt is intended to be used to facilitate snow and ice prevention and removal on County of Ocean roads and bridges.
