Reinforced Earth®: Mechanically Stabilized Earth Abutment Walls

In 1996 the Vermont Agency of Transportation (VAOT) completed the state's first mechanically stabilized earth (MSE) abutment walls in the Town of Wallingford, Vermont. The project involved construction of a 100-ft simple steel girder bridge on U.S. Route 7 over the Vermont Railway. MSE technology was selected because it solved the problem of constructing abutments in a confined work zone and did so at a considerable cost savings when compared to using reinforced concrete pilings. The product under study is a proprietary system of the Reinforced Earth Company®. The system is composed of concrete facing panels which are attached to layers of steel reinforcing strips in compacted select backfill material. The project site has been continuously monitored since before construction with an extensive array of geotechnical instrumentation, including settlement platforms, inclinometers, earth pressure cells, and monitoring wells. Data collected from this project will provide a valuable reference for future use of MSE technology by VAOT.
