When Tony Allen, P.E., was at work on his civil engineering master’s thesis at Oregon State University in the early 1980s, he certainly couldn’t have foreseen the impact it would have during the next 30 years on geotextiles and geogrids in reinforcement applications. Of great importance, the work he pursued then (and since) has led to real understanding of the durability of geosynthetic reinforcements. Read more about the impact T925 has had on reinforcement design and specification in the United States and internationally. The article, from Geosynthetica’s Chris Kelsey, appears in the May 2010 issue of CE News.
