Humbolt has released a Nuclear Gauge App to allow you to capture nuclear density gauge test results using your phone. The app works using QR codes generated on the Humboldt EZ-2 Nuclear Gauge. You can […]
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.
This is a commentary written by Jaye Richardson, a materials operation manager with AMEC Earth and Environmental, Inc. It appeared in CE News in August of 2010, but I just came accross it in CENews.com’s […]
Time again for a summary of changes to ASTM standards that may be of interest to geotechnical engineers, engineering geologists and those in geoconstruction and even lab testing or CQA. This month there is a new standard for a new type of geomembrane, revisions to standards relating to ultrasonic testing and general nondestructive testing terminology, evaluation of particle shape in aggregates, and re-approval of standards relating to non-asbestos fiber-cement based products.
