Point of Discussion: |
A
specification on non-woven geotextile that NO standard product in
the market is capable of meeting |
Current specification on non-woven geotextiles
used in filtration applications
must have a tensile elongation of <30%. But:
-
Maximum value is not specified
in the
international geotextiles
standards, only
a minimum range
of
15% to
50%
-
Non-woven geotextile is
to be with large
elongation, a characteristic of production
-
A
geotextile with large elongation is
considered
beneficial
in filtration application. Large elongation is not expected in situations
where soil is confined and well compacted.
Review or
amendment to this particular specification is sought.
