ASTM Updates for March, 2012

April 16, 2012 rockman Comments Off

American Society of Testing Materials Logo - ASTM This post contains a list of new, revised and otherwise updated ASTM standards that pertain to the geotechnical engineering, materials testing and related fields. Standard C39/C39M for testing the compressive strength of concrete cyllinders was updated, as was C42/42m for obtaining and testing drilled cores and sawed beams of concrete. The month of March also saw several geosynthetic standards being updated or added, including new standards for selecting the test method for geomembrane seams, and for testing the flexural rigidity of geogrids and other geosynthetics. There are also a few updated standards related to asphalt mix design and sampling of asphalt. Click through for updated ASTM Standards relating to geoprofessionals.

ASTM Updates for April 2011

April 1, 2011 rockman Comments Off

American Society of Testing Materials Logo - ASTM It’s that time again. Here are a collection of changes/additions to ASTM standards that are relevant to geotechnical engineers, soils labs, CQA firms and related disciplines. There are a couple of interesting new standards available. D7698 is a new procedure for estimation of in-place density and water content of soil and aggregate by correlation with complex impedance. I’m not eactly sure what that is, but it sounds cool. There is also a new standard (D7702) that provides guidance for the evaluation of direct shear results involving geosynthetics. Read on for these and other updates.

ASTM Updates September 2010

October 4, 2010 rockman Comments Off

American Society of Testing Materials Logo - ASTM Last month there were several updates to standards involving texting the flexural strength of concrete as well as updates to some masonry and dimension stone standards. ASTM D6926 – Standard Practice for Preparation of Bituminous Specimens Using Marshall Apparatus has been updated, so if you are involved in asphalt pavement testing, make sure you go and find out what the changes are. There are also a whole slew of groundwater and site investigation standards that were reapproved.
