Investigation of Road Salt Alternatives and Pavement Innovations

Principal Investigator(s):

John Gulliver, Professor, Civil, Environmental and Geo-Engineering


  • Bruce Wilson, Professor, Bioproducts and Biosystems Engineering

Project summary:

The goal of this project is to investigate and enhance strategies that improve water quality by evaluating road salt alternatives and pavement innovations to reduce the chloride load from road runoff. The methods and tools developed during this project will inform state, municipal, and private entities using chloride-based salt on roads and parking lots. A feasibility matrix will be developed to summarize high-level economic, environmental, time frame, implementation, and maintenance challenges/benefits for alternate strategies.
