D35 on Geocomposite Long-Term Drainage Efficiency
02/06/2012
ASTM Committee D35 on Geosynthetics has announced work item WK36298, "New Test Method for Long Term Efficiency of Drainage Geocomposites." The work item's scope notes that it is intended to determine the potential loss of efficiency caused by biological or chemical growth which can develop in a drainage geocomposite; and to obtain an indication that both the filter and the core of a drainage geocomposite will remain functional over an extended period of time. Proof of leachate collection layer performance is key to the work item. ID:

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:

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:
