Geocomposite lamination strength ASTM test method: Time for an update
August 1st, 2018
Recent project experience that included continuous peel testing across the roll width of geocomposite materials has shed light on the issue of peel strength between geotextiles and geonets that are heat-bonded together. The variability of peel strength across a roll width is found to be much greater than expected, with the typical standard deviation often […]
Geosynthetics use expands in mining and ore processing
August 1st, 2018
The estimated value of nonfuel mining of raw materials in the United States alone totaled $75.2 billion in 2017, according to an annual report by the U.S. Geological Survey (USGS). Everything from aluminum to zinc falls into this massive category, but that dollar figure is dwarfed by the USGS’s estimate in that same report of […]

One of the few professional engineers in Congress, Republican Rep. Bruce Westerman of Arkansas pulls no punches when discussing the potential use of geosynthetics in federal infrastructure projects. “I think geosynthetics should be part of the toolkit,” Westerman said during a phone interview with Geosynthetics magazine on May 19. First elected to Congress in 2014 […]

It follows then that some 200 years later, manufactured geosynthetic materials should do likewise. In fact, so-called standards organizations have evolved by publishing the following […]
