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.
