Overview

ISO 22182:2020 specifies an index test method to determine the abrasion resistance of geotextiles and geotextile‑related products under wet conditions for hydraulic applications. The standard simulates abrasion caused by moving rock and sediment (e.g., in embankments, rivers, or beneath armourstone) using a rotating drum filled with water and defined crushed‑basalt aggregates. Results are reported as abrasion‑resistance ratios for mechanical and hydraulic properties and can be used for performance and acceptance testing.

Key topics and technical requirements

• Test principle: Specimens mounted in an octagonal rotating drum are exposed to abrasive basalt chippings and water; the drum performs two abrasion phases of 40 000 revolutions each, with rotation reversed every 5 000 revolutions.
• Apparatus: Octagonal steel drum with eight test sections, adjustable motor and control system, specimen mounting plates and seals.
• Abrasive mixture (specified composition):
  • 2 kg of 8/11 mm crushed basalt
  • 1 kg of 5/8 mm crushed basalt
  • 1 kg of 2/5 mm crushed basalt
  • 8 L water
  • Basalt particle density ≈ 3.0 ± 0.2 Mg/m³; water absorption ≤ 2 %; Micro‑Deval (M_DE) between 10 and 15.
• Specimens and conditioning: Eight test and eight control specimens per run, size 200 × 300 mm (exposed area 280 × 170 mm). Store under water at (20 ± 5) °C for ≥24 h prior to testing.
• Operating parameters: Drum speed 16 r/min; water temperature 18–22 °C.
• Measured properties (before and after abrasion): tensile strength (ISO 9073‑3), mass per unit area (ISO 9864), characteristic opening size (ISO 12956), filtration behaviour (ISO 10772), water permeability (ISO 11058).
• Results: Abrasion resistance R expressed as percentage ratios (property after / property before × 100), reported to 0.1 % resolution. Test report requirements are specified (mean, SD, CV, visual description, number of runs, etc.).

Applications and who uses it

ISO 22182 is used by:

• Geosynthetic manufacturers for product development, QA/QC and acceptance testing of geotextiles intended for geobags, filters beneath armourstone, revetments and riverbank protection.
• Independent testing laboratories to produce comparable index data.
• Civil, coastal and hydraulic engineers to select appropriate geotextiles for erosion‑ and abrasion‑prone environments.
• Specifiers and procurement teams requiring standardized performance evidence in contracts.

Practical benefits include standardized comparison of materials, assessment of durability after simulated hydro‑abrasive exposure, and informed selection for long‑term hydraulic installations.

Introduction
The abrasion resistance under wet conditions is an important property for the application of geotextiles
intended to be used as geobags (geotextile bags filled with soil) or filter beneath armourstone. The
abrasion impact on geotextiles can be achieved under wet conditions by installing geotextile samples in
a rotating drum. In the fixed rotating drum test facility, the drum is rotated with a defined speed and is
filled with water and a mixture of angular-grained high-quality basalt chippings with determined sizes.
The abrasion impact is caused by crushed stones tumbling over the geotextile. The assessment of the
geotextile abrasion resistance characteristics can be achieved by comparing thickness and mechanical
properties (tensile strength, elongation) and/or additional hydraulic properties (characteristic opening
size, filtration behaviour) before and after abrasion impact.
