    Brief Project Description & Background
    Many products are available for use in highway and bridge deicing and new products are introduced each year. Data from the manufacturer provides theoretical performance information under specified conditions. A test procedure for acceptance of new commercial deicing chemicals is needed to confirm the manufacturers claim and to compare competing products under the same controlled conditions and at various application rates. The purpose of this project is to present all of the current information to the TAC members, and generate a best practices summary of data collected from other agencies.
    Research Objective
    The objective of the project is to gather and summarize existing information regarding accepted test methods intended for use to evaluate de-icing material performance, quality assurance/quality control (QA/QC) procedures used elsewhere, and current research underway.
    Potential Benefits
    This study will provide a method of evaluating new commercial deicing chemicals to confirm manufacturers’ claims and help find the most efficient, cost-effective product.
    Abstract
    The cost of deicing chemicals is a significant part of the Nebraska Department of Roads (NDOR’s) winter maintenance budget. The use of deicing chemicals is increasing each year to improve a Level of Service and the price of chemicals is also going up each year. The use of Maintenance Decision Support System (MDSS) allows users to be more precise in the selection of chemicals and the application rate for specified weather and pavement conditions. Many products are available for use in highway and bridge deicing and new products are introduced each year. Data from the manufacturer provides theoretical performance under specified conditions. A test procedure for acceptance of new commercial deicing chemicals is needed to confirm the manufacturers claim and to compare competing products under the same controlled conditions and at various application rates. The purpose of this project is to present all of the current information to the TAC members, and generate a best practices summary of data collected from other agencies in the US and Canada.
