• Abstract:
  The goal of this project was to investigate the effects of additives commonly used in deicers for winter road maintenance operations, explore the qualitative and quantitative benefits of these additives, laboratory and performance data, impacts, and relative performance to sodium chloride (NaCl). Additionally, evaluate the impact additives have on solid rock salt performance measured as eutectic temperature. To accomplish a literature review, surveys of state and local agencies and deicing product vendors and manufacturers, and laboratory testing including eutectic temperature and or freezing point, a modified ice melting capacity Rocker Test Method for solids and measuring pavement friction were completed. Conclusion, recommendations, and suggested future research to support this effort are provided.
