ASTM Updates for April 2011

American Society of Testing Materials Logo - ASTMIt’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.
