Geosynthetic-reinforced soil brigde abutments
The technology of geosynthetic-reinforced soil (GRS) systems has been used extensively in transportation systems. A comparatively new use of this technology is the use of GRS systems as an integral structural component of bridge abutment and piers. Use of a reinforced soil system to support directly both the bridge and the approaching roadway structure has the potential of significantly reducing construction costs. The most prominent GRS abutment for bridge support in the United States is the Founders/Meadows Parkway bridge, which crosses U.S. Interstate 25 approximately 20 miles south of downtown Denver and was recently opened to traffic. This is the first major bridge in the United Staates to be built on footings supported by a geosynthetic-reinforced system, eliminating the use of traditional deep foundations altogether. The perfomance of the Founders/Meadows bridge structure showed excellent short- and long-term performance; the monitored movements were significantly smaller than those expected in design or allowed by performance requirements.
