本文件描述了模拟土工合成材料在重复荷载下由粒状材料引起的机械损伤的指数试验程序。通过视觉和拉伸强度损失来评估损伤。 其他参考测试可用于评估该测试造成的损坏。所述试验方法为指数试验程序，使用标准粒状材料，不用于推导土工合成材料加固的折减系数。

This document describes an index test procedure for simulating mechanical damage to geosynthetics, caused by granular material, under repeated loading. The damage is assessed visually and by the loss of tensile strength. Other reference tests can be used to assess the damage caused by this test. The test method described is an index test procedure, using a standard granular material, and is not intended to be used for the derivation of a reduction factor for geosynthetic reinforcement.
