The replacement of the CDOT Region 1 Twin Bridge over Smith Road and Union Pacific Rail Road (UPRR) on I-70 provided an excellent opportunity for the performance evaluation of GRS (geosynthetically reinforced soils) abutment. The performance of the GRS abutment was measured using SAA (shape accel array) for lateral deformation and vertical settlement measurement, Geokon 4810 for horizontal earth pressure, 4800 for vertical earth pressure, 4420 for...

Various reinforced earth retaining walls were constructed in Glenwood Canyon to accommodate for the possible large differential settlements of the foundation soils. The first time these walls were constructed with 10-foot wide and 20-foot high fascia panels. These panels admirably withstood severe differential settlements.
