• Abstract:
  To identify roadway-adjacent areas that are likely to have a greater sensitive to deicing chemicals, specifically chlorides, this project conducted a literature search to describe the effects of deicing chemicals, the factors which mitigate or increase their impacts, and constructed a geospatial model that uses a variety of descriptive data to estimate the relative sensitivity of the local environment. The model allows users to define roadways that are subject to deicing operations, adjust relative importance of various factors such as land use, and generate a high-medium-low thematic map of the roadways. This tool will allow a more thoughtful and targeted approach to chloride use reduction by enabling an analysis of environmental impact that can be balanced against other concerns such as safety and pavement clearing time targets.
