Understanding the Effectiveness of Non-Chloride Liquid Agricultural By-Products and Solid Complex Chloride/Mineral Products

Agriculturally derived products, or agro-based products, and complex chloride mineral (CCM) based products are increasingly employed in snow and ice control operations, either used alone or more commonly as additives or blended with traditional chloride-based products such as rock salt (solid sodium chloride) and salt brine (liquid sodium chloride). Past studies and manufacturers have claimed that agro-based or CCM based products provide benefits such as freezing point depression, prolong performance on the road surface, the ability to utilize UV light as an aid to ice prevention, and various environmental benefits. However, the measurement of the effectiveness of such products has been limited. To further investigate the role CCM and agro-based products may have in deicing and corrosion protection, a literature review and national survey were conducted to identify potential products, how they are typically used, performance characteristics, and pros and cons. Ten products were selected for extensive laboratory testing which investigated the products ability to lowering the freezing point of water and improve the ice melting capacity, weaken the ice bond to pavement, improve the product longevity on the road surface, prevent ice formation or refreeze prevention, and assess the influence of absorbance of sunlight on product performance. Results of the laboratory testing and literature review were used to develop a best practices manual. This report documents the work completed for each task of this project, as well as provides a presentation of the major findings.
