Keyline-Tensar partnership offers large-aperture geogrid
Construction supplier Keyline has teamed with Tensar International to offer new technology for the U.K. rail sector—a geogrid for better mechanical stabilization of rail track beds.
The new product (TX190L) is a large-aperture geogrid designed to delay track deformation and reduce maintenance calls, making it a potential solution for weak or variable stiffness foundations. The new product replaces previous biaxial geogrids because it is better able to distribute loading and mechanically stabilize larger-sized aggregate such as railway ballast, according to the manufacturer.
John Dixon, area civil engineer at Tensar said: “Keyline is the ideal partnership for us within the U.K. [This] geogrid will provide their customers with an effective solution that has been developed to better control track geometry, reduce maintenance costs, and extend the life of track renewal.”
