New Test Method for Determining the Omni-Axial Tensile Performance of Geogrids at Low Strain

1. Scope

2.1 The scope of the Committee shall be the formulation of test methods, specifications, guides, practices, terminology, and the dissemination of knowledge dealing with geosynthetics. This would include but not be limited to geotextiles, geogrids, drainage nets, drainage composites, geosynthetic clay liners, geosynthetic erosion control products and sediment retention devices, geosynthetic strips, geofoam and geomembranes.
2.2. The formulation of test methods, specifications, guides, practices and terminology for Geosynthetic related products shall be considered by the Committee by establishment of special subcommittees approved by the Executive Subcommittee.
2.3 The work of this Committee will be coordinated with other ASTM committees or organizations having mutual interest.

Keywords

deformation; geosynthetics; multi-axial; omni-axial; tension; low strain

Rationale

At present, there is no test method available to determine a common index value for the tensile performance of geogrids and geotextiles manufactured with different alignments of their constituent tensile elements, for example, geogrids with two sets of tensile elements and square apertures and geogrids with three sets of tensile elements and triangular apertures. Index values of multi-axial load at a low strain (2 %) will be used by government agencies and other specifiers in material specifications to aid free choice of material irrespective of the arrangement of its tensile elements.

The title and scope are in draft form and are under development within this ASTM Committee.
