Title:

Prediction of Brine Application for Pretreatment/Anti-icing

Abstract:

An effective anti-icing program requires prediction/estimation of the amount/type/timing of chemicals needed for the expected precipitation event, while compensating for time/traffic decay of the chemical on the highway surface. Development of a sodium chloride brine anti-icing methodology was accomplished via an extensive study of brine residual decay on four pavement types. An instrument that dissolves salt and measures conductivity was utilized to measure available salt residual. Efficacy of the brine to prevent ice/surface bonding was estimated utilizing freeze/thaw cycles of various brines. Results support estimation of brine application requirements for three specific pavements based on expected precipitation and the salt residual models developed in the study.
