Geosynthetics - Determination of compression behaviour - Part 1: Compressive creep properties (ISO 25619-1:2008); English version of DIN EN ISO 25619-1:2009-06
This part of ISO 25619 specifies index test methods for determining the compressive creep properties of
geosynthetic products. The test specimens are subjected either to normal compressive loading or to a
combination of normal compressive loading and shear loading.
The test method with a normal load only (see Clause 5) is the standard method
The test method in which both normal and shear loads are applied (see Clause 6) is intended for products that
are sensitive to shear failure, i.e. which have a columnar or cuspated structure.
The tests are carried out on dry specimens or on specimens immersed in water. The test is intended to be
carried out with the specimen immersed in water when any part of the geosynthetic product contains a
hydrophilic polymer.
