Geosynthetics - Determination of friction characteristics - Part 2: Inclined plane test (ISO/DIS 12957-2:2023); German and English version prEN ISO 12957-2:2023
Abstract
This document describes a method to determine the friction characteristics of geosynthetics (geotextiles and geotextile-related products, geosynthetic barriers), in contact with soils, or between another geosynthetic, at low normal stress, using an inclining plane apparatus. This test method is primarily intended as a performance test to be used with site specific soils but is also used as an index test with standard sand. It is also possible to measure the displacement of the interface over time (creep phenomenon) without necessarily reaching the slippage failure. Test data obtained for geogrids tested with a rigid support are not necessarily realistic as the results depend on the friction support.
