Testing of tensile properties of two nonwoven geotextiles

Abstract

The use of geosynthetics has become a common and unavoidable practice in geotechnical engineering, agriculture and environmental engineering. The main disadvantages of earthen construction materials are their insufficient tensile strength and inadequate water permeability or impermeability, depending on the problem to be solved. Such shortcomings are successfully solved by incorporating appropriate geosynthetics (geotextile, geogrid, geocells, geomembrane etc.) into earthen structures. The most used geosynthetic is geotextile, which can provide practically all functions expected from such a product. The aim of this paper was to present and analyse the relative results of multiple tensile tests performed on two nonwoven (NW) geotextiles to provide a realistic insight into the variability of their tensile properties. The obtained results showed a very similar variability of the tensile properties of the tested geotextiles.
