Geosintetika. Bandymo metodas, nustatyti polimerinių geosintetinių užtvarų pleišėjamąjį atsparumą veikiant aplinkai

This document specifies a test method for screening the resistance of polymeric geosynthetic barriers to stress cracking. The test is applicable to polypropylene and polyethylene based products and to all other polymeric geosynthetic barriers which have a partially crystalline structure. NOTE The described method is suitable for conformance testing of smooth surfaced (non-textured) geosynthetic barriers. However the resistance to stress cracking of the resin used in the manufacture of structured surface materials can be evaluated by carrying out the test on a plaque formed from the relevant resin (see 4.5) or, where structuring is carried out as a separate processing step, on a preformed smooth surface geosynthetic barrier, the test can be performed on the intermediate smooth material. The data are suitable for screening and determination of conformity but not for deriving performance data such as lifetime, unless supported by further evidence.
