Geosynthetics - Determination of friction characteristics - Part 2 : inclined plane test

ISO 12957-2:2005 describes a method of determining the friction characteristics of geosynthetics (geotextiles and geotextile-related products, geosynthetic barriers), in contact with soils, at low normal stress, using an inclining plane apparatus.This method is primarily intended as a performance test to be used with site-specific soils but may also be used as an index test with standard sand.Test data obtained for geogrids tested with a rigid support are not necessarily realistic as the results depend on the friction support.

Geomembranes. Measurement of the geomembrane lining systems slipping angle by means of an inclined plane test.

Le présent document définit une méthode de détermination, à l'aide d'un plan incliné, de l'angle de glissement des différentes interfaces d'un DEG (dispositif d'étanchéité par géomembrane) tels que : sol (ou matériau rigide), géomembrane, géotextile, Les résultats obtenus permettent d'analyser la stabilité au glissement des DEG avec les sols et les matériaux utilisés sur le chantier, dans le cas de faibles contraintes normales. Cette méthode d'essai constitue un essai de performance ; elle complète l'essai d'identification défini par la norme NF P 84-505.

Geosynthetics - Determination of friction characteristics - Part 2 : inclined plane test

This document specifies a method to determine the friction characteristics of geosynthetics (geotextiles and geotextile-related products, geosynthetic barriers) in contact with soils or another geosynthetic, at low normal stress, using an inclining plane apparatus. This test method is primarily intended as a performance test to be used with site specific soils but is also used as an index test with standard sand. It is also possible to measure the displacement of the interface over time (creep phenomenon) without necessarily reaching the slippage failure. Test data obtained for geogrids tested with a rigid support are not necessarily realistic as the results depend on the friction support.
