and where it is required to survive on-eld installation related stresses.
Mechanical properties of geotextile are often categorized as in-isolation
properties and performance properties. In-isolation properties are deter-
mined on the geotextiles itself with the absence of surrounding soil.
Performance properties are determined on geotextiles in the presence of
site-specic soil.
a. Tensile properties: The determination of tensile properties, such as ten-
sile strength and tensile modulus, of geotextile is important and is
carried out by wide-width strip tensile testing. Geotextile specimen
of at least 200 mm wide with a gage length of 100 mm is clamped
within the co ...
