Abstract:Geosynthetics are currently perceived to be “under-used in the Federal Lands Highway (FLH) practice.” Accordingly, this study aims to develop recommendations to identify, promote, and advance the use of geosynthetic materials across the FLH in the Roadway, Bridge/Structures, and Geotechnical areas. Personnel from the FLH and its client organizations were surveyed to determine current use and barriers to implementation of geosynthetic technologies. A review of recent literature and existing national design guidelines was undertaken to determine the current state of practice and possible technologies that could be implemented in the near future. Recommendations are formulated to provide the basis for a multi-year effort that will culminate in advancing the use of geosynthetic materials in the FLH projects. These include updates to current geosynthetic specifications, development of training programs and analysis tools that focus on applications of interest to the FLH, and needed further studies to promote the improvement of nascent or existing design methods.
