Abstract

One of the important applications of geosynthetics in the slopes, such as landfills and waste disposal areas, is to use them as lining systems. To create the above conditions, most geosynthetics are placed in multilayer systems in the slopes. In these cases, the interaction between the geosynthetic–geosynthetic composite system interfaces should be controlled. To characterize the friction at the geosynthetic interface, a European Standard describes the test with an inclined plane apparatus under low stress. Many studies have shown that this procedure is not able to determine the friction for many interfaces. In 2011, the “Force Procedure” was proposed to better characterize the friction angle at the geosynthetic interface. This new procedure still requires validations to be proposed to replace the existing European standard. Two new inclined planes have been developed to compare the force procedure with the displacement procedure on many geosynthetic interfaces and to confirm the interest to revise the European Standard.
