Presentation Title: Furthering Compost Use by Departments of Transportation
Presentation Description: Each State Department of Transportation (DOT) publishes construction specifications that outline how to carry out work from closing traffic lanes to applying plant seed after highway construction has finished. Our research question was: How is compost use prescribed by state DOTs? Each state’s DOT specification document was assessed for if/how compost use is prescribed. For analysis, we relied on recommendations from the U.S. Composting Council (USCC) and the American Association of State Highway and Transportation Officials (AASHTO), and findings from previously published journal articles.
Most states had some mention of compost, but specifications varied widely. Many states outlined using compost for erosion control. The particle size distribution requirements differed from state to state significantly. Many of the requirements outlined by the USCC and AASHTO were not incorporated into design specifications for each state. Overall, DOTs would benefit from using compost effectively and efficiently. The findings from this study can be used to guide communication with DOTs and aid in development of the next iterations of design specifications.
