The test\n    reproduces surface wear by pressing a prepared specimen against a moving abrasive surface under a controlled load.\n    Once the specified number of rubbing cycles is complete, the worn specimen undergoes tensile testing to establish\n    the strength remaining after abrasion. The reduction in tensile strength, expressed as a percentage, provides a\n    measurable indication of the material's resistance to long-term wear.\u003c\/p\u003e\n\u003cp\u003eQualitest North America offers the QualiGTX™ GAT for geosynthetic manufacturers, independent testing facilities, and\n    civil engineering laboratories responsible for material qualification and quality control. Its testing mechanism\n    maintains a 6 kg normal load with an accuracy of ±0.01 kg and moves the lower platen through a 25 mm stroke at a\n    constant rate of 90 cycles per minute. An adjustable counter accommodates test sequences ranging from 2 to 99,999\n    cycles. By maintaining consistent loading, movement, and operating frequency, the instrument enables meaningful\n    comparisons between manufacturing batches and materials submitted by different suppliers.\u003c\/p\u003e\n\u003cp\u003eGeotextile deterioration often develops gradually rather than becoming apparent during construction. Continuous\n    contact with ballast, shifting aggregates, settling soil, and hydraulic forces can progressively damage individual\n    fibers and reduce the fabric's ability to withstand tensile loading. The QualiGTX™ GAT recreates this type of\n    repeated mechanical wear under controlled laboratory conditions, allowing engineers and quality control teams to\n    assess material durability before installation in road embankments, landfill lining systems, and railway track beds.\n\u003c\/p\u003e\n\u003ch2\u003eGeotextile Abrasion Tester – QualiGTX™ GAT

geotextile fibers gradually reduces the material's ability to carry\n    tensile loads. Under continuous contact pressure, abrasive particles produce localized cutting and fatigue damage as\n    individual filaments bend, deform, develop surface fibrillation, and eventually break. This deterioration reduces\n    the amount of intact fiber available to resist applied tension. Consequently, a geotextile can experience a\n    substantial loss of mechanical strength before visible perforations or other obvious surface defects develop.\n    Measuring the tensile strength remaining after abrasion therefore provides a more meaningful assessment of material\n    damage than visual examination alone.\u003c\/p\u003e\n\u003cp\u003eThe QualiGTX™ GAT evaluates this deterioration through a controlled two-plate abrasion arrangement. During setup, the\n    operator secures a 50 mm × 200 mm geotextile specimen to the stationary upper plate and attaches the abrasive paper\n    to the corresponding lower plate. A 6 kg mass applies pressure between the two surfaces, maintaining consistent\n    contact during the test. The lower plate then moves back and forth through a 25 mm stroke at a frequency of 90\n    cycles per minute. A digital counter monitors the number of completed cycles and stops the test when the selected\n    count is reached.\u003c\/p\u003e\n\u003cp\u003eThe extent of abrasion depends on the combined effect of three test parameters: applied contact pressure,\n    reciprocating stroke length, and total number of cycles. Maintaining consistent pressure and stroke conditions\n    allows laboratories to evaluate different materials under comparable test conditions, while the selected cycle count\n    determines the duration of abrasive exposure.\u003c\/p\u003e\n\u003cp\u003eAfter abrasion testing, the specimen is removed and placed in a tensile testing machine to determine its breaking\n    force. This result is compared with the tensile strength of an unabraded control specimen taken from the same roll.\n    The relationship between the two measurements establishes the percentage of tensile strength retained following\n    abrasion. The reduction from the original strength represents the percentage of strength lost, providing a numerical\n    basis for comparing geotextile abrasion resistance and evaluating material durability. \u003c\/p\u003e\n\n\n\u003ch2\u003eGeotextile Abrasion Tester - QualiGTX™ GAT Technical Specifications\u003c\/h2\u003e\n\u003ctable class=\"table table-style-align-center\" align=\"center\" border=\"1\" cellspacing=\"0\" cellpadding=\"0\"\u003e\n    \u003cthead\u003e\n        \u003ctr\u003e\n            \u003cth\u003eParameter\u003c\/th\u003e\n            \u003cth\u003eSpecification\u003c\/th\u003e\n        \u003c\/tr\u003e\n    \u003c\/thead\u003e\n    \u003ctbody\u003e\n        \u003ctr\u003e\n            \u003ctd\u003eUpper Plate Dimensions\u003c\/td\u003e\n            \u003ctd\u003e50 mm × 200 mm\u003c\/td\u003e\n        \u003c\/tr\u003e\n        \u003ctr\u003e\n            \u003ctd\u003eLower Plate Dimensions\u003c\/td\u003e\n            \u003ctd\u003e50 mm × 200 mm\u003c\/td\u003e\n        \u003c\/tr\u003e\n        \u003ctr\u003e\n            \u003ctd\u003eLower Plate Stroke\u003c\/td\u003e\n            \u003ctd\u003e25 ±1 mm\u003c\/td\u003e\n        \u003c\/tr\u003e\n        \u003ctr\u003e\n            \u003ctd\u003eReciprocating Frequency\u003c\/td\u003e\n            \u003ctd\u003e90 cycles per minute\u003c\/td\u003e\n        \u003c\/tr\u003e\n        \u003ctr\u003e\n            \u003ctd\u003eSpecimen Load\u003c\/td\u003e\n            \u003ctd\u003e6 ±0.01 kg\u003c\/td\u003e\n        \u003c\/tr\u003e\n        \u003ctr\u003e\n            \u003ctd\u003eAbrasion Cycle Range\u003c\/td\u003e\n            \u003ctd\u003e2 to 99,999 cycles, user-programmable\u003c\/td\u003e\n        \u003c\/tr\u003e\n        \u003ctr\u003e\n            \u003ctd\u003eSpecimen Types\u003c\/td\u003e\n            \u003ctd\u003eWoven geotextiles, nonwoven geotextiles, geotextile-related products\u003c\/td\u003e\n        \u003c\/tr\u003e\n        \u003ctr\u003e\n            \u003ctd\u003eTest Output\u003c\/td\u003e\n            \u003ctd\u003eTensile strength loss expressed as a percentage\u003c\/td\u003e\n        \u003c\/tr\u003e\n        \u003ctr\u003e\n            \u003ctd\u003eOverall Dimensions\u003c\/td\u003e\n            \u003ctd\u003e600 × 400 × 500 mm\u003c\/td\u003e\n        \u003c\/tr\u003e\n        \u003ctr\u003e\n            \u003ctd\u003eNet Weight\u003c\/td\u003e\n            \u003ctd\u003e45 kg\u003c\/td\u003e\n        \u003c\/tr\u003e\n    \u003c\/tbody\u003e\n\u003c\/table\u003e","brand":"Qualitest USA LC","offers":[{"title":"Default Title","offer_id":53606243926327,"sku":null,"price":100.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0786\/1859\/1543\/files\/geotextile-abrasion-tester117955.webp?v=1794491230","url":"https:\/\/qualitest.us\/pt\/products\/geotextile-abrasion-tester","provider":"Qualitest USA LC","version":"1.0","type":"link"}
