Geosynthetics - Index test procedure for the evaluation of mechanical damage under repeated loading - Damage caused by granular material
ISO 10722:2007 describes an index test procedure for simulating mechanical damage to geosynthetics, caused by granular material, under repeated loading. The damage is assessed visually and by the loss of tensile strength.

La présente prénorme internationale décrit une procédure d'endommagement des géosynthétiques en laboratoire pour simuler l'endommagement sur site lors de la pose d'un géosynthétique entre deux couches de matériaux granulaires compactés. L'endommagement est évalué visuellement ainsi que la détermination de la perte de résistance de traction. D'autres essais de référence peuvent être utilisés pour évaluer l'endommagement provoqué par l'essai. La méthode d'essai décrite est un essai de caractérisation. La présente prénorme constitue la première partie d'une série de deux prénormes. La seconde partie décrira une méthode d'essai simulant l'endommagement lors de la pose d'un géosynthétique sur un sous-sol meuble.
This document describes an index test procedure for simulating mechanical damage to geosynthetics, caused by granular material, under repeated loading. The damage is assessed visually and by the loss of tensile strength. Other reference tests can be used to assess the damage caused by this test. The test method described is an index test procedure, using a standard granular material, and is not intended to be used for the derivation of a reduction factor for geosynthetic reinforcement.

The Requirements department helps you quickly locate within the normative text:
- mandatory clauses to satisfy,
- non-essential but useful clauses to know, such as permissions and recommendations.
The identification of these types of clauses is based on the document “ISO / IEC Directives, Part 2 - Principles and rules of structure and drafting of ISO documents ”as well as on a constantly enriched list of verbal forms.
