Geosynthetics - Determination of the pyramidal puncture resistance of supported geosynthetics

Le présent document décrit une méthode pour la détermination de la résistance au poinçonnement des géosynthetiques. L'essai consiste à mesurer la force nécessaire pour perforer une éprouvette de géosynthétique posée sur un support rigide en acier à l'aide d'un poinçon de forme pyramidale. Par simulation cette méthode permet d'évaluer la capacité d'un géosynthétique à protéger une géomembrane contre les éléments rigides ou tranchants sous une charge à court terme.
