Understanding the NaCl Phase Diagram

The goals of this project are to provide winter maintenance practitioners with a better understanding of the sodium chloride (NaCl) phase diagram and of how brines with salt concentrations higher or lower than the eutectic point of 23.3% will behave on the roadway. This knowledge will help winter maintenance agencies apply salt and salt brines effectively for the best performance on winter roadways.
