2、 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, or

4、 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 This

5、 guide is not applicable for factory fabricated panels due to a different set of identifications for the panel by thefabricator. For Fabricated Geomembrane Panels, refer to Guide D7865.1.4 This guide is not intended for Geosynthetic Clay Liners. For GCLs, refer to Guide D5888.1.5 This guide is also

17、purposes. (see(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 supplier, nthe person or organiz

18、ation 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 are fully met.4. Significance

19、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 geosynthetic in a properly desig

20、ned 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 Cores shall When cores are required, use those that have a

21、 crushing strength sufficient to avoid collapse or other damagein normal use.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 each roll with a

22、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 the width and len

23、gth 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 traceability. All designa

24、tions 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 While unloading or t

25、ransferring 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 the length of the rolls to avoid bre

26、aking the cores and possibly damaging the geotextile. Slings may be usedto carry relatively rigid rolls provided that the slings do not cause damage to the rolls. Do not drag the rolls as damage may result.5.2.2 Geotextiles, when possible, should be stored elevated off of the ground and covered to e

27、nsure 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,5.2.2.5 Temperatures in exc

28、ess of 160F (71C)71C and below 32F (0C)0C (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 with placement.5.3 On-Site Handling:

29、5.3.1 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.D4873/D4873M 1625.3.2 Before unrolling a roll at the job site, verify its identification.
