Geosynthetics - Determination of friction characteristics - Part 1 : direct shear test

This document specifies an index test method to determine the friction characteristics of geosynthetics in contact with a standard sand as described in EN 196-1, i.e. with a specified density and moisture content, under a normal stress and at a constant rate of displacement, using a direct shear apparatus. The same testing procedure can be used with any type of soil with the density and moisture content that are required to evaluate the performance under specific conditions or with another geosynthetic under a normal stress and at a constant rate of displacement, using a direct shear apparatus. The procedure can also be used for testing geosynthetic barriers.

Geosynthetics - Determination of friction characteristics - Part 1 : direct shear test

Le présent document décrit une méthode de détermination des caractéristiques de frottement des géotextiles et des produits apparentés, en contact avec un sable normalisé, à une masse volumique et une teneur en humidité spécifiées, sous l'effet d'une contrainte normale et à une vitesse de déplacement constante, en utilisant un dispositif de cisaillement direct. Ce mode opératoire peut également être utilisé pour les essais sur géomembranes et géosynthétiques bentonitiques.
