Popis
BS EN ISO 12957-1:2018
This standard BS EN ISO 12957-1:2018 Geosynthetics. Determination of friction characteristics is classified in these ICS categories:
- 59.080.70 Geotextiles
This document specifies an index test method to determine the friction characteristics of geosynthetics in contact with a standard sand as described in EN 196‑1, i.e. with a specified density and moisture content, under a normal stress and at a constant rate of displacement, using a direct shear apparatus.
The same testing procedure can be used with any type of soil with the density and moisture content that are required to evaluate the performance under specific conditions or with another geosynthetic under a normal stress and at a constant rate of displacement, using a direct shear apparatus.
The procedure can also be used for testing geosynthetic barriers.
