ASTM D4595 Wide-Width Strip Method Tensile Properties of Geotextiles Test Machine

ASTM D4595 – 17 : Standard Test Method for Tensile Properties of Geotextiles by the Wide-Width Strip Method

This test method covers the measurement of tensile properties of geotextiles using a wide-width strip specimen tensile method. This test method 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, for example design of reinforced embankments over soft subgrades, reinforced soil retaining walls, and reinforcement of slopes.

When strength is not necessarily a design consideration, an alternative test method may be used for acceptance testing.

Test Method D4595 for the determination of the wide-width strip tensile properties of geotextiles may be used for the acceptance testing of commercial shipments of geotextiles, but caution is advised since information about between-laboratory precision is incomplete (Note 6). Comparative tests as directed in 5.1.1 may be advisable.
