Abstract:The Oregon Department of Transportation (ODOT) conducted a study to examine roadwaste management options. Phase 1 consisted of a thorough review of regulations and standards, roadwaste characterization, current management practices, and new technology. Phase 2 researched promising alternatives and gathered data in field trials. This report documents the efforts of Phase 3, providing guidance to ODOT maintenance personnel on the protective and cost effective management of roadwaste materials.
Roadwaste categories are identified and risk is assessed. Identifying and separating differing roadwastes allows more ready management while requiring less frequent analysis. District-level baseline waste characterizations help identify the most appropriate management methods to address actual risks. Recommended practices address testing, “hot” load separation, mainstream roadwaste, and wet waste management. Ready reuse is available for some materials. Other materials require simple treatment. More contaminated materials may require a significant investment in treatment or ongoing tracking unless a conservative management option is selected; e.g., disposal in a permitted landfill.
A statewide plan cannot account for all of the varying circumstances and environmental conditions in the state; District-level plans are needed. This guide supports the development of District-level roadwaste management plans by providing an understanding of the roadwaste types and associated risks, what an overall roadwaste plan must address, and details on specific workable options.
The ODOT Research Group plans to support the development of several District Roadwaste Management Plans, both by sponsoring training on the use of this guide and offering support for plan development. The recommendations provided in this guide coupled with further work by ODOT Districts developing roadwaste plans may lead to negotiations with environmental regulatory agencies leading to formal adoption of roadwaste Best Management Practices.
