CALTRANS goes GREEN with Biaxial Geogrid to Save Tax Payer's Gr$$n
02/02/2012
Caltrans is one of the first major pavement administrations to formulate a post-patented biaxial geogrid specification and design standard to be adopted when Tensar International's "punched-and-drawn" high-performance geogrid patent expires in May of this year. "This is a big deal. Not only for the geogrid industry in California but the tax payers as well", said Ray Meyers, Co-Chairman of the Pavement Committee put together by Deepak Maskey, P.E. of Caltrans last fall. ID:

D35 Work Item on Long-Term Connection Strength
02/02/2012
ASTM Committee D35 on Geosynthetics has announced work item WK36264, "Test Method for Determining Long-Term Connection Strength Displacement (Creep) Between Geosynthetic Reinforcement and Segmental Concrete Units (Modular Concrete Blocks)." This is a performance test used to determine properties for design of retaining wall systems utilizing segmental concrete units and soil reinforcing geosynthetics, either geotextiles or geogrids. The test is performed on a full-scale construction of the connection and may be run in a laboratory or the field. ID:

Benson and Daniel to Deliver Key Lectures at Geo-Congress 2012
02/02/2012
The Geo-Institute of ASCE's annual congress offers an exceptional opportunity to interact with the international geotechnical engineering community on some of the most pressing topics. Geo-Congress 2012 will be held in Oakland, California 25-29 March 2012. The theme of the event is "State of the Art and Practice in Geotechnical Engineering" and some noted engineers with a geosynthetics background (Craig Benson and David Daniel) will deliver two of the three big lectures: the Ralph B. Peck and Karl Terzaghi Lectures. ID:

Sinkhole Mitigation with Geosynthetics
01/30/2012
Land and Water magazine has profiled how geosynthetics have been used around the world to mitigate sinkhole formation, expansion and infrastructure impact. Among the projects profiled in Chris Kelsey's article is the exemplary work performed by Maccaferri in Union Bridge, Maryland. There, geosynthetic reinforcement helped construct a road key to continued economic success for the town. Situated on tenuous soils, the geosynthetic solution turned an otherwise unbuildable project into a reality. ID:

A Better Way for the Beltway
01/30/2012
In an article in Geosynthetics magazine, Maccaferri's Alan Dinges profiles the Interstate-95/495 Capital Beltway upgrade near Washington, D.C. The 24 lane-miles of road required 321,000 yards of paving, 11 bridges, drainage improvements, retaining and noise-abatement walls, and environmental mitigation. Geogrids and geotextiles were effective construction components in this project’s diverse range of soil reinforcement and separation requirements. Read Alan's cover story from the issue. ID:

PRCI Conducts Geotextiles for Pipeline Stability Research
01/25/2012
The Pipeline Research Council International (PRCI), a 60-year-old not-for-profit industry group, is currently reviewing a Final Report on "Assessment of Geosynthetic Fabrics to Reduce Soil Loads on Buried Pipelines." According to the the PRCI's latest update on the collaborative research, "This research determined that the use of two layers of geotextile fabric on a sloped trench boundary is effective in reducing maximum horizontal soil loads at small displacements with observed reductions of approximately 30% and 40% in the horizontal soil restraint provided by gravel for various trench wall angles." The project has aimed to find a methodology and approach that would be repeatable, in the lab and in the field. ID:
