description: The introduction and rise in use of geosynthetic materials in the 20th century has helped develop the field of civil engineering as well as some other fields. Studying the durability properties of geogrids in order to understand the materials behavior as reinforcement is vital, as geosynthetics are replacing conventional construction materials. A variety of tests have to be performed, in an effort to increase the available data for geosynthetics, so that it can replace conventional construction materials.
Two of the most common geosynthetic materials used to make high-strength geogrids are polyester (PET) and polyvinyl alcohol (PVA). This study will extensively analyze the creep behavior of PET and PVA yarns and geogrids through stepped isothermal method (SIM), time-temperature superposition principle (TTS), and stepped iso-stress method (SSM). The tensile and creep testing of PET and PVA yarns will be carried out in a laboratory with testing apparatus and international procedures.
The computerized data that is acquired from the tests will be used to create a master curve, their initial creep rates, and load-strain behavior, which will be used to analyze the durability properties of both PET and PVA yarns and their relation to polymeric geogrids.
The acquired data from this study will provide a simple isochronous graph that can be utilized when the creep behavior of geogrids is required with the purpose of designing different structures that require geogrids as reinforcement.
