Two new standards from the Geosynthetics committee of ASTM will help define properties that can be used in the design of geosynthetic reinforced pavement. I know in my practice in Arizona, ADOT simply allows a boost of Resilient Modulus (R-Value) of 10 when biaxial geogrids are used. Perhaps in time this will lead to a design method to account for the geosynthetic reinforcement in a more analytical way. [Source: Geosynthetics Magazine]

ASTM Updates March 2009
Our monthly update on new and revised ASTM standards that relate to geotechnical engineering, materials testing, hydrogeology, geosynthetics and related disciplines. This month there are a few notable revisions, including D1452 for Auger Borings, D3385 for Double-Ring Infiltrometer and D4595 for determining tensile properties of geotextiles by the wide-width strip method. There are also a few other geotextile, groundwater, lime, masonry and terminology standards that were added or updated. Click through for the full list.
