Pendergrass, Ga.-based TenCate Geosynthetics North America — a division of the Netherlands-based
Royal Ten Cate — reports that its Mirafi® BXG base reinforcement geogrids outperformed all tested
biaxial geogrids, including traditional extruded biaxial geogrids, in an independent study
performed for the Montana Department of Transportation (DOT) and the Federal Highway Administration
examining the use of reinforcement geosynthetics in unsurfaced roads built on soft subgrades.
In the study, the Western Transportation Institute evaluated eight geogrids against two
control sections and found that TenCate’s Mirafi BXG woven geogrids enabled high strength
transference from geogrid to soil, preventing rupturing. The study reports the TenCate geogrids had
“very little rib damage” and provided better rutting performance than the other geogrids that were
evaluated.
“We are extremely pleased with the results of this independent study,” said Brett Odgers, PE,
roadway reinforcement market manager, TenCate Geosynthetics. “Our geogrid production technology has
allowed us to produce the most effective reinforcement geogrid available on the market. We are also
pleased that this research finally dispels the myth that old extruded geogrid technology
outperforms the revolutionary woven geogrid technology.”
