Artificial Lake Anti-Seepage Geosynthetics: There are three kinds of new anti-seepage materials for artificial lakes, namely HDPE anti-seepage membrane, PE composite geomembrane, and GCL geosynthetic clay liner. ...
Most of the universal geomembrane test methods cited worldwide are developed by ASTM International because ASTM has a long history in this activity. The update is the test method developed by the International Organization for Standardization (ISO). Finally, the Geosynthetics Research Institute (GRI) has developed test methods ...
It’s not a very efficient way to convey water,” notes Joe Kaul, Kaul Corporation, Presto Geosystems’ Western States represen‐ tative and geosynthetics supplier. Usbor Testing Performance A 10‐year canal lining study by the US Bureau of Reclamation (USBOR) tested four canal types for a multitude of fac‐ tors ...
Opened in 1987, the municipal landfill Ämmässuo in Finland extends over 50 ha, making it one of the largest in all of Scandinavia. Two test fields were set up to find a suitable solution for the surface sealing system and future slope reinforcement The structure of these fields consists of a mineral gas-drain layer, a mineral sealing layer, a ...
An upper anchor trench was excavated along the outside perimeter of the access road at the top of the slope to anchor the various geosynthetic products that formed the liner system and final slope cover. ...
This technical note describes a new apparatus and testing procedure to perform rapid quality control and assessment of the design parameters of geosynthetic materials. The cylindrical expansion test (CET) is based on the principles of the extension of a geosynthetic specimen wrapped around the surface of an expanding thin-wall ...
The in-plane flow behavior of four geosynthetics, including three geonets and one geocomposite, for landfill drainage applications was investigated. ...
A modification of an old test method, the notched constant tensile load (NCTL) test, is reintroduced to evaluate the stress-cracking performance of high-density polyethylene (HDPE) geomembranes. In this modified test, notched dumbbell-shaped specimens are subjected to a range of constant tensile loads in a 10% Igepal (CO-630) solution at 50°C. ...
While there exist many types of mechanical tests for use on geosynthetics, most seem to be more suitable for one type of system or another. This paper focuses on a test which may have widespread applicability to assess the strength of all types of geosynthetics. ...
