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 High Value Research award.
The research evaluated the performance of concrete heated with embedded electrodes – constructed in the parking lot at Iowa DOT’s headquarters in Ames – over the course of three years. The concrete, which can melt snow and ice without the use of deicers, could one day be a sustainable option for icy trouble spots like sidewalks that are not easily cleared during winter storms.
Iowa is no stranger to the High Value Research award, having earned eight of these awards since 2013, including one just last year for its research into corn-based deicers as an alternative to traditional chloride- and acetate-based solutions for keeping snow and ice from forming on the state’s roadways.
AASHTO’s Research Advisory Committee will recognize all 2022 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 2023.
