Research Idea Scope
Research: Independent laboratory data on the performance of deicing chemicals and blends of chemicals will be collected. Existing data will be reviewed and verified. Additional testing will be conducted to establish performance data on blends of chemicals.
Urgency and Payoff
Public agencies are under extensive pressure to provide safe winter operating conditions while reducing application rates to lessen both cost and environmental impact.Managers require objective information to select, store and apply chemicals in an efficient manner. The growing use of chemical blends creates the need for current and objective chemical performance data. Savings in maintenance budgets and improved performance will result when the data collected from this study is available. It will benefit all State DOTs and local agencies responsible for winter road and airport maintenance. The benefits can be realized immediately following the conclusion of this project.
