GEOTECH WALL DESIGN AND CONSTRUCTION. FINAL REPORT

The first two full scale "American Geotech Walls" were constructed as wing walls for a highway bridge over a railroad near Harrisburg, PA by the Pennsylvania Department of Transportation. This method utilizes the passive earth pressure from the backfill soil acting on "deadmen" to the "face panels." This report summarizes the design, specifications, construction and performance of these walls. Also included herein are test results, interpretation summary and conclusions. This system performed well, did not require special backfill and therefore is more economical compared to other proprietary walls. Except for some design and construction changes that are needed this system is recommended for highway projects involving walls of 40 ft. in height or less and where no unusual soil or loading conditions exist.
