THE TESTING OF GEOTEXTILES. SUGGESTIONS FOR A TEST PROGRAMME

DIE PRUEFUNG VON GEOTEXTILIEN. VORSCHLAG FUER EIN PRUEFPROGRAMM

Geotextiles, i.e. textiles (woven and non-woven) used in earthworks, have achieved increasing significance in recent years. All attempts to draw up quality requirements for these materials have to assume that suitable testing procedures are available. The author introduces a Swiss proposal for a testing programme which he, together with a technical committee of the VSS, has produced. This programme consists of three sections: description, durability and mechanical qualities. It still needs to be supplemented by a programme for testing hydraulic qualities. The first section "description" encompasses construction data which do not necessarily have to be checked, such as the description of the material, the form of the components, the structure of the textile and the area weight. Within the section on "durability" are considered the tests for biological stability, resistance to ultra violet rays and resistance to chemical influences. The test for "mechanical qualities" include: determination of weight per unit area and thickness (under two different loadings), longitudinal tensile strength test (for non-wovens, also with a stretcher), ascertaining the further resistance to tearing, the falling cone test and determination of creep behaviour.
