Foreword
IS0 (the International Organization for Standardization) is a worldwide
federation of national standards bodies (IS0 member bodies). The work of
preparing International Standards is normally carried out through IS0
technical committees. Each member body interested in a subject for which
a technical committee has been established has the right to be represented
on that committee. International organizations, governmental and non-
governmental, in liaison with ISO, also take part in the work. IS0
collaborates closely with the International Electrotechnical Commission
(IEC) on all matters of electrotechnical standardization.
The main task of technical committees is to prepare International
Standards, but in exceptional circumstances a technical committee may
propose the publication of a Technical Report of one of the following types:
when the required support cannot be obtained fo r the
- type 17
on of an lnternationa Standard despite repeated efforts;
publicat Y
- type 2, when the subject is still under technical development or where
for any other reason there is the future but not immediate possibility of
an agreement on an International Standard;
- type 3, when a technical committee has collected data of a different
kind from that which is normally published as an International
Standard (“state of the art”, for example).
Technical Reports of types 1 and 2 are subject to review within three years
of publication, to decide whether they can be transformed into International
Standards. Technical Reports of type 3 do not necessarily have to be
reviewed until the data they provide are considered to be no longer valid or
useful.
ISOTTR 107224, which is a Technical Report of type 2, was prepared by
the European Committee for Standardization (CEN) in collaboration with
IS0 Technical Committee TC 38, Textiles, Subcommittee SC 21,
Geotextiles, in accordance with the Agreement on technical cooperation
between IS0 and CEN (Vienna Agreement).
Throughout the text of this Technical Report, read “. this European
prestandard . .” to mean “. this part of ISOTTR 10722 . .“.
This document is being issued in the Technical Report (type 2) series of
publications (according to subclause G.3.2.2 of part 1 of the ISO/IEC
Directives, 1995) as a “prospective standard for provisional application” in

the field of the simulation of site damage during installation of a
geosynthetic in granular materials because there is an urgent need for
guidance on how standards in this field should be used to meet an
identified need.
This document is not to be regarded as an “International Standard”. It is
proposed for provisional application so that information and experience of
its use in practice may be gathered. Comments on the content of this
document should be sent to the IS0 Central Secretariat.
A review of this Technical Report (type 2) will be carried out not later than
three years after its publication with the options of: extension for another
three years; conversion into an International Standard; or withdrawal.
Annex ZZ provides a list of corresponding International and European
Standards for which equivalents are not given in the text.

1 Scope
This European prestandard describes a procedure for damaging geosynthetics in
the laboratory to simulate site damage during installation when a geosynthetic is
laid between two layers of compacted granular material. The damage is
assessed visually and by the loss in tensile strength. Other reference tests may
be used to assess the damage caused by this test. The test method described is
an index test procedure.
This prestandard is part 1 of a series of 2 prestandards. Part 2 will describe a
test procedure for damage simulation when a geosynthetic is laid on a soft
subsoil.
2 . Normative References
This European Prestandard incorporates by dated or undated reference,
provisions from other publications. These normative references are cited at the
appropriate points in the text and the publications are listed hereafter. For dated
references, subsequent amendments to or revisions of any of these publications
apply to this European Standard only when incorporated in it by amendment or
revision. For undated references, the latest edition of the publication referred to
applies.

3 . Definitions
For the purpose of this European prestandard the following definitions shall
apply:
3.1 Reference test: the test used to determine a particular property of the
geosynthetic being damaged in the procedure;
3.2 Damage index: the percentage change of the particular property used as a
measure of the damage caused by the procedure.
4 . Principle
A geosynthetic specimen is placed between two layers of a synthetic aggregate
and subject to a period of dynamic loading. The geosynthetic specimen is
removed from the test apparatus, examined for any visual damage and then
subject to a mechanical or hydraulic test, to measure the change in mechanical
or hydraulic properties. The result is expressed as the change (in percent) of the
reference property. The visual damage is also reported.
