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]
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.
July 23, 2009 – Engineers, architects, contractors, code officials and others in the construction industry need access to ASTM standards referenced in the 2009 International Building Code (IBC) to design, construct and regulate safe and reliable buildings. The ASTM Standards: As Referenced in the 2009 International Building Code fulfills this need in one book.
This comprehensive book contains 280 ASTM referenced standards in Chapter 35 of the IBC, including critical topics such as structural steel, concrete, masonry, wood, soil, gypsum, insulation, fire protection, fire prevention, window fall prevention devices, and other important areas that contribute to safe and quality construction.
