2、e of revision, the year of last revision. A number in parentheses indicates the year of lastreapproval. A superscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 This guide provides guidelines for the identification and packaging of rolled geosynthetics

3、 by the manufacturer and for thehandling and storage of geosynthetics by the end user. This guide is not to be considered as all encompassing since each projectinvolving geosynthetics presents its own challenges and special conditions. Geosynthetic samples are often taken at manufacturer,supplier, o

4、r at the job site primarily for the purpose of conformance testing and verification. These samples should be properlylabeled for identification purposes.1.2 This guide is intended to aid manufacturers, suppliers, purchasers, and users of geosynthetics for identification, handling,and storage.1.3 Thi

5、s guide is not applicable for factory fabricated factory-fabricated panels due to a different set of identifications for thepanel by the fabricator. For Fabricated Geomembrane Panels,fabricated geomembrane panels, refer to Guide D7865.1.4 This guide is not intended for Geosynthetic Clay Liners. For

Terminology3.1 Definitions:3.1.1 For definitions of geosynthetic terms, refer to Terminology D4439.3.1.

16、2 For definitions of textile terms, refer to Terminology D123.3.2 Definitions of Terms Specific to This Standard:3.2.1 core, na mandrel of cardboard, foam, or other material on which geosynthetics are rolled during manufacturing tofacilitate handling.3.2.2 sample, n(1) a portion of material which is

17、 taken for testing or for record purposes. (See also sample, lot; sample,laboratory; and specimen.) (2) a group of specimens used, or of observations made, which provide information that can be usedfor making statistical inferences about the population(s) from which the specimens are drawn.3.2.3 sup

18、plier, nthe person or organization from whom a geosynthetic is purchased or otherwise obtained.3.2.3.1 DiscussionThe supplier is frequently the manufacturer of the geosynthetic, but need not be.Asupplier who is not the manufacturer is expectedto ensure that the responsibilities of the manufacturer a

19、re fully met.4. Significance and Use4.1 For a geosynthetic to be properly used it must be adequately identified and packaged. It must be handled and stored in sucha way that its physical property values are not degraded. Failure to follow good practice may result in the unnecessary failure ofthe geo

20、synthetic in a properly designed application.4.2 This guide is not intended to replace project-specific storage, handling, identification, packaging, or installationrequirements or quality assurance programs.5. Procedure Geotextiles5.1 Packaging and Identification:5.1.1 When cores are required, use

21、those that have a crushing strength sufficient to avoid collapse or other damage in normaluse.5.1.2 Cover each roll with an opaque wrapping material for protection from damage due to shipment, water, sunlight, orcontaminants while being stored or handled in accordance with this guide.5.1.3 Identify

22、each roll with a durable, gummed label, or equivalent, clearly readable on the roll packaging or on the inside ofthe core. Roll identification should include, at minimum, the name of the manufacturer or supplier, product or style number, andthe unique roll number. Identification should also include

23、the width and length of roll. Any other unique characteristics should beclearly identified. For rolls with no identification on the inside of the core, once the roll is unwrapped or samples taken, labels onthe outer wrap of the roll packaging should be removed and placed inside the roll for traceabi

24、lity. All designations should bereadable for clear identification.NOTE 1Rolls bundled or strapped as a single unit could be regarded as a single roll for identification purposes provided all the rolls remain as a singleunit received by the end user.5.2 Receiving and Storing at the Job Site:5.2.1 Whi

25、le unloading or transferring the geotextile from one location to another, prevent damage to the wrapping and to thegeotextile itself. If practicable, use fork lift trucks fitted with poles that can be inserted into the cores of rolls. Be sure that the polesare at least two thirds two-thirds the leng

26、th of the rolls to avoid breaking the cores and possibly damaging the geotextile. Slingsmay be used to carry relatively rigid rolls provided that the slings do not cause damage to the rolls. Do not drag the rolls as damagemay result.5.2.2 Geotextiles, when possible, should be stored elevated off of

27、the ground and covered to ensure adequate protection fromthe following:5.2.2.1 Precipitation (because geotextile roll goods saturation leads to handling difficulties),5.2.2.2 Ultraviolet radiation,5.2.2.3 Undesirable chemicals for any extended period of time,5.2.2.4 Flames, including welding sparks,

28、5.2.2.5 Temperatures in excess of 160F 71C160 F 71 C and below 32F 0C32 F 0 C (see Note 2), and5.2.2.6 Any other environmental condition that may damage the physical property values of the geotextile.NOTE 2Geotextiles may contain enough moisture to cause them to stiffen when frozen, which interferes

29、 with placement.5.3 On-Site Handling:D4873/D4873M 1725.3.1 While transferring geotextiles from one location to another, prevent damage to the wrapping and to the geotextile itself.Follow the cautions specified in 5.2.1.5.3.2 Before unrolling a roll at the job site, verify its identification. While u

30、nrolling the geotextile, inspect it for damage ordefects.5.3.3 Follow all applicable site or project specifications and manufacturers recommendations for handling and installation.5.3.4 Correct any damage that occurs during storage or installation as directed by the project specifications and the en

Cutsample according to specified test method(s).5.4.2 Identify each sample with a durable, gummed label, or equivalent including, at a minimum, the sample designation, thename of the manufacturer or supplier, product or style number, the lot number or roll number, or both, location sampled or

33、 projectname or project identification number, sampled by, and date sampled. If third party is responsible for sampling, include with thename, the address, and telephone number.5.4.3 Sample should be suitably packaged for shipping to prevent distortion. Sample should be packaged in suitable wrapping

Roll identification should include, at minimum, the nameof the manufacturer or supplier, product or style number, and the unique roll number. Identification should also include the widthand length of the roll. Any other unique charact

37、eristics should be clearly identified. For rolls with no identification on the insideof the core, once the roll is unwrapped or samples taken, labels on the outer wrap of the roll packaging should be removed andplaced inside the roll for traceability.
