I’ll be brief since I have already mentioned this in a previous post and in the July GeoPrac newsletter. But today was the 40th Anniversary of the first time humans set foot on the moon. I’m embarrassed to say, but I mistakenly noted this historic anniversary as the 20th instead of the 40th anniversary in both of the above links. I’m surprised nobody called me on this, but I guess you ridiculed me in private. If you haven’t already, check out the wonderful article by Ed Nowatzki on the geotechnical engineering aspects of the lunar lander…fascinating reading, even for non-geotech types.

ASTM Updates for April 2011
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.
