Geotextiles are used with foundation, soil, earth, and rock material as an integral part of man-made project, structure, or system. Geotextiles are a permeable geosynthetic comprised solely of textiles. Geotextile materials prevent the erosion of earth and similar substances after the area has been altered due to construction usually pertaining to civil engineering applications such as roads, pavement, bridges, embankments and retaining walls. They allow the passage of water but not soil and other materials.
The ASTM and ISO standards containing these methods are ASTM D4595 for geotextiles, ISO 10319 for geosynthestics, and ISO 10321 for joints and seams in geosynthetic materials. Wide width tensile strip tests typically require test machines with a greater load capacity than standard textile strip tests.
ASTM D4595 measures the tensile properties of geotextiles using a wide-width strip specimen tensile method. ASTM D4595 is applicable to most geotextiles that include woven fabrics, nonwoven fabrics, layered fabrics, knit fabrics, and felts that are used for geotextile application. The determination of the wide-width strip force elongation properties of geotextiles provides design parameters for reinforcement type applications.
