Iowa’s research into the viability of using corn-based deicers—an alternative to traditional chloride- and acetate-based solutions—to keep snow and ice from the state’s roadways has earned accolades from peer states in the Midwest and national recognition.
Each year, the American Association of State Highway and Transportation Officials (AASHTO) honors the best transportation research projects from each of its four regions with a prestigious AASHTO “Sweet 16” award.
This year, Iowa’s research into the environmental benefits of using agro-based deicing blends was deemed to be innovative and worthy of this award by the agency’s eight peers in AASHTO Region 3: Illinois, Indiana, Kansas, Michigan, Minnesota, Missouri, Ohio, and Wisconsin.
Iowa is no stranger to the Sweet 16 award, having earned 7 of these awards since 2013, including one just last year for its Remote Controlled Hydrographic Survey System, a boat with data collection equipment that engineers can control remotely to quickly and safely survey Iowa bridges.
AASHTO’s Research Advisory Committee will recognize all 2021 winners during its summer meeting in July. Winners will also participate in a poster session dedicated to high-value research projects at the annual meeting of the Transportation Research Board in Washington, DC in January 2022.
