Austroads Technical Specification ATS 2170 sets out the requirements for the supply and installation of geosynthetic reinforcement, which is used in applications such as:
- a) embankment basal reinforcement (for example, embankments over soft ground);
- b) piled embankments with basal reinforcement; and
- c) reinforcing of embankments with a batter slope ≤ 70° from horizontal.
ATS 2170 only applies to high strength geosynthetic products, which may include geogrids, straps and woven products.
ATS 2170 does not cover any of the following:
- a) geosynthetic reinforcement for reinforced soil structures (refer to ATS 5120);
- b) geotextiles used as separation and/or filtration elements in earthworks construction (refer to ATS 2160); and
