GRIPgrain® (Chinese Calcined Bauxite for HFST)
Great Lakes Minerals, LLC (GLM) is happy to play a key role in keeping drivers safe on U.S. roadways.
High Friction Surface Treatment (HFST) is a cost effective approach to address areas on our roadways, such as horizontal curves, intersections or bridges, that demand higher friction in order to reduce vehicle speeds, ultimately increase safety and decrease crashes.
Chinese calcined bauxite is the aggregate of choice for HFST because of its abrasive qualities, hardness, and ability to hold frictional resistance over time. GLM’s calcined bauxite for HFST, GRIPgrain®, is the highest quality bauxite available in China (rotary-kiln fired) and sized to State specification in our modern and quality controlled U.S. sizing plant. Dust collectors on all of GLM’s sizing circuits ensures the finished product is virtually dust-free. GLM packages all GRIPgrain® in quality, durable, spout-bottom 4000 lb bulk bags; rain caps are added to keep material extra dry.
Great Lakes Minerals, LLC is well positioned to supply all of your HFST aggregate needs!
