A question from Germany
We are searching for the actual version of GRI-GG2. My latest version is from 2000.
What is the newest version?
Where can I get it?
With kind regards.
Reply: Our latest revision of GRI-GG2 on geogrid junction strength is Revision 3—Aug. 1, 2005. We will send it to you.
That said, ASTM has subsequently adopted its own test method. It is designated D7737. They look to be the same, but there may be differences.
