Meet Robert
Robert K. Barrett
Bob was a founder and was Director of Innovation for GeoStabilization International. He was Chairman of NCHRP Project 12-59, charged with preparing Design and Construction Guidelines For Bridge Abutments on Geosynthetically Reinforced Soil.
ast Chair of the TRB Committee on Geosynthetics, and the NCHRP project that developed proper closure methods for geotechnical borings. Recipient of 1991 Colorado Governor’s Award for creativity and innovation. Ruckman and Barrett were recipients of the IFAI International Design Award in 1997 for design and construction of a 55-foot-high GRS retaining wall.
Co-Recipient of the international 2009 NOVA award from the Construction Innovation Forum for development of GCS bridge abutments. Partner Al Ruckman and Mr. Barrett have been awarded 7 patents, on retaining wall design, on rockfall fences, on earthquake resistant abutments on fiberglass nails, on shotcrete alternatives and on scour micropiles.
Co-inventor of the Colorado Rockfall Simulation Program, a program that predicts the behavior of a rock in motion. We have presented GRS, landslide mitigation and rockfall technology transfer programs all over the U. S. and on all continents except Africa. Constructed GRS abutment and wall demonstration projects in several countries.
The Unfinished Story of Geosynthetically Confined Soil
This detailed publication explores the history, mechanics, and technical foundations of GCS® technology. It explains how soil confinement influences structural behavior and why this method has such high performance.
Also includes appendix and research supporting practical design, testing, and construction considerations.
