RES2023-14: Improved Management Strategies of Processing Acid Producing Materials on Transportation Projects
| 项目名称： | RES2023-14: Improved Management Strategies of Processing Acid Producing Materials on Transportation Projects |
| 摘要： | Roadway excavation cuts in Tennessee frequently encounter rock, shale, or soil materials that could be considered acid producing material (APM). The geotechnical material properties of APM are adequate for roadway fill, but the APM produces acidic leachate that creates a condition of environmental pollution. Tennessee Department of Transportation (TDOT) has prepared a guidance manual in 2007 for dealing with these types of projects. TDOT routinely uses these design and construction protocols for proper handling of APM with APM processing strategies consist of blending with lime, relocating to landfills, or placement in engineered encapsulation cells on-site or off-site. These strategies, however, result in considerable increases in project costs and reductions in construction productivity, thus driving the need to assess current APM construction procedures to enhance the management of APM encountered in TDOT roadway projects with improved cost effectiveness and construction productivity. |
