标准范围
This document 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 combined 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.
