In an open letter to geotechnical engineers and agencies that specify geosynthetics on their projects, the Geosynthetics Manufacturers Association (GMA) has requested that specifiers use the correct standards when referring material properties of geotextiles and other geosynthetics. For example, they refer to two standards that are now out of date, The Mullen Burst Strength and the Puncture Test which were both originally designed for paper. The correct standard is the Static (CBR) Puncture ASTM D6241. See the entire letter on Geosyntheticsmagazine.com. (Photo of Geotextiles from Nilex.com)
