EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of EN ISO 12957-1 testing. EN ISO 12957-1 defines a method for determining the frictional properties of geotextiles and geotextile-related products in contact with a standard sand, i.e. sand of a given density and moisture content, under normal stress and at a constant displacement speed.
Geosynthetics are synthetic materials used in civil engineering and geotechnical applications to improve the mechanical properties of soils and provide other functions such as reinforcement, separation, filtration and drainage. The frictional properties of geosynthetics play a crucial role in their performance when interacting with adjacent materials such as soils or other geosynthetic layers.
The Direct Shear Test is a widely accepted method for evaluating the frictional behavior of geosynthetics. It involves placing a sample of geosynthetic material between two layers of material (for example, soil) with which it will be in contact, and then subjecting it to shear forces parallel to the planes of the layers. The test apparatus allows for controlled shear and the force required to cause relative motion between the geosynthetic and adjacent materials is measured.
The test helps determine the coefficient of friction between the geosynthetic and the adjacent material, which measures the resistance to sliding or sliding at the interface. This coefficient is necessary to understand the interaction between geosynthetics and soil or other geosynthetic materials, especially in applications such as retaining walls, embankments and slope stabilization.
EN ISO 12957-1 provides a standardized and consistent method for performing the Direct Shear Test on geosynthetics, allowing manufacturers, engineers and researchers to evaluate and compare the frictional properties of different materials. Understanding these frictional properties is crucial for designing geosynthetic reinforced structures that perform optimally and meet safety and stability requirements in civil engineering projects.
