What is ASTM test for geotextile?

There are several ASTM tests for geotextiles, depending on the specific properties being evaluated. Here are a few examples:

ASTM D5261: Standard Test Method for Measuring Mass per Unit Area of Geotextiles

ASTM D4632: Standard Test Method for Grab Breaking Load and Elongation of Geotextiles

ASTM D4533: Standard Test Method for Trapezoid Tearing Strength of Geotextiles

ASTM D4491: Standard Test Method for Water Permeability of Geotextiles by Permittivity

These tests evaluate properties such as mass per unit area, tensile strength, tear resistance, and water permeability, which are important for determining the effectiveness of a geotextile in a given application.
