Abstract
The aim of this work was to provide an investigation of nonwoven geotextiles resistance to the environment. When a geotextile is used in a civil engineering structure, it is intended to perform a particular function for a minimum expected time.It should be chemically and biologically resistant, whilst the assessment of the geotextiles durability and application requires a study. Therefore, in this research, the geotextile resistance was investigated in three directions: the resistance to microbiological attack by soil burial (EN 12 225), the resistance to the oxidation (ISO 13438) and the resistance to liquids (acid and alkali, EN 14030). All the samples were tested before and after the exposure according to standardized methods for determination of mechanical (CBR and strip test) and chemical properties (absorption, adsorption, specific amount of surface charge)
