StrataGRS is used in the Integrated Bridge System as part of the FHWA’s Every Day Counts (EDC) initiative. This system reduces bridge construction time and cost. Instead of conventional bridge support technology for bridge abutments, Geosynthetic Reinforced Soil (GRS) Integrated Bridge System (IBS) technology uses alternating layers of compacted granular fill material and closely spaced geosynthetic reinforcement to provide support for the bridge. GRS also provides a smooth transition from the bridge onto the roadway, and alleviates the “bump at the bridge” problem caused by uneven settlement between the bridge and approaching roadway.
