Abstract:This document presents guidelines to facilitate the evaluation of brines for winter weather roadway maintenance applications in Texas. Brines are used in anti-icing applications which typically consist of placing liquid snow and ice control chemicals onto the roadway surface prior to the storm event. These chemicals depress the freezing point and prevent snow and ice from forming a bond to the roadway surface. Anti-icing also helps by weakening the bonds that are formed and allowing for easier plowing of snow and ice. Because the chemical is applied prior to receiving snow and ice, anti-icing is termed a “proactive” winter weather maintenance strategy.
