Geotextile Abrasion Testers

Geotextile Abrasion Testers | ASTM D4886 & ISO 13427 Sliding Block Method

Geotextile abrasion testers measure how much tensile strength a fabric loses after repeated rubbing against an abrasive surface, the figure engineers use to predict service life against aggregate. The sandpaper and sliding block method defined in ASTM D4886 and ISO 13427 clamps a specimen under a 6 kg dead load while a platen reciprocates beneath it.

Geosynthetic producers, contract laboratories, and civil engineering departments rely on this test to qualify woven and nonwoven fabrics before installation. Qualitest North America offers the QualiGTX™ range in two bench configurations, both running identical test parameters.

Why Choose Qualitest for Your Geotextile Abrasion Tester

Qualitest North America supplies testing and measurement equipment to laboratories, quality teams, and manufacturers, backed by responsive technical support and calibration service. The Geotextile Abrasion Tester range is built for reliable, standards-driven results, so you can source confidently from a single partner. Our team helps you match the right configuration to your samples, applicable standards, and throughput, then supports you through installation and beyond.

Applications

Abrasion testing applies wherever a geosynthetic will spend its service life in contact with soil, stone, or coarse fill.

Geotextile Manufacturing QC: lot-by-lot verification that production output holds its rated abrasion resistance before shipment.
Rail Ballast Engineering: qualification of trackbed fabrics that face angular crushed stone under repeated axle loading.
Highway and Subgrade Separation: durability screening of separation layers between soft subgrade and granular base course.
Geomembrane Cushion Layers: assessment of protection geotextiles that shield liners from drainage stone in landfill and pond works.
Riprap and Scour Protection: evaluation of filter fabrics installed beneath armor stone on riverbanks and coastal defenses.
Third-Party Certification: independent abrasion reporting for tender review, project acceptance, and product certification files.

Geotextile Abrasion Tester Range

Both models run the same method at the same parameters. The difference is bench geometry, so the choice comes down to how your laboratory is laid out rather than to test capability.

How to Choose the Right Geotextile Abrasion Tester

For standard laboratory benches with open depth: choose the GAT, whose 600 mm width leaves room for the tensile machine used in the follow-up strength measurement.
For narrow wall benches or instrument rows: choose the GAT SB, which trades length for a 350 mm depth that fits tighter runs.
For either test scope: both models deliver the same 6 kg load, 25 mm stroke, and 90 cycles per minute, so neither limits which fabrics you can test.
For laboratories without a tensile frame: plan for wide-width tensile equipment alongside either model, since the abrasion result comes from residual breaking force rather than from the abrasion tester itself.
