1、Designation: D 1751 04 (Reapproved 2008)Standard Specification forPreformed Expansion Joint Filler for Concrete Paving andStructural Construction (Nonextruding and ResilientBituminous Types)1This standard is issued under the fixed designation D 1751; the number immediately following the designation

2、indicates the year oforiginal adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencie

3、s of the Department of Defense.1. Scope1.1 This specification covers preformed expansion jointfiller having relatively little extrusion and substantial recoveryafter release from compression.1.2 The values stated in inch-pound units are to be regardedas standard. The values given in parentheses are

Ordering Information3.1 Produ

6、cts conforming to this specification are manufac-tured in sheet form to a range of thicknesses; namely14 ,38 ,12 ,34 , and 1 in. Sheet sizes may be 3 or 4 ft in width andstandard length of 10 ft. Purchaser must specify sheet sizeswhen ordering.3.2 Joint filler in strip form is cut from the sheets as

7、manufactured. When ordering joint filler strips, the purchasermust specify thickness, width, and length; strip widths areavailable from 2 in. in increments of one half inch.4. Material4.1 This product shall consist of preformed sheets or stripsmade from cane or other suitable fibers of a cellulosic

8、naturesecurely bound together and then uniformly saturated withasphalt; or strips formed from clean granulated cork securelybound together by a suitable asphalt binder and encasedbetween two layers of saturated felt or two layers of glass-fiberfelt.4.2 Preformed strips of expansion joint filler shal

9、l be of suchcharacter as not to be deformed or broken by twisting, bending,or other ordinary handling when exposed to atmosphericconditions.5. Requirements Requirements5.1 Test SpecimenThe sample to be tested shall be cutfrom the sheet, as manufactured, and shall be representative ofthe sheet stock.

10、5.2 CompressionThe stress required to compress the testspecimen to 50 % of its thickness before test shall be not lessthan 100 and not more than 750 psi (689 to 5171 kPa). If thenominal thickness of the specimen is less than12 in. (13 mm),a maximum stress of 1250 psi (8618 kPa) will be permitted.The

11、 sample after compression, shall show a loss of not morethan 3 % of its original weight.5.3 ExtrusionTest specimen shall be compressed to 50 %of its thickness before test with three of its edges restrained.The amount of extrusion of the free edge shall not exceed 0.25in. (6.4 mm).5.4 RecoveryThe tes

12、t specimen shall be compressed to50 % of its thickness before test. The load shall be releasedimmediately after application. At the end of 10 min afterrelease of the applied load, the specimen shall have recoveredto at least 70 % of its thickness before test.1This specification is under the jurisdic

13、tion of ASTM Committee D04 on Roadand Paving Materials and is the direct responsibility of Subcommittee D04.34 onPreformed Joint Fillers, Sealers and Sealing Systems.Current edition approved Dec. 1, 2008.

15、, PO Box C700, West Conshohocken, PA 19428-2959, United States.5.4.1 In case of failure to comply with the above require-ments, the test specimen shall be given three applications of aload sufficient to compress the material 50 % of its thicknessbefore test. The load shall be released immediately af

16、ter eachapplication. At the end of 1 h after the third application, thespecimen shall have recovered to at least 70 % of its thicknessbefore test.5.5 DensityFor fibre joint only, oven dry the specimen at220 6 5F (104 6 3C) for 2 h. after oven drying, cool thespecimen to room temperature in a covered

17、 desiccator, andweigh to nearest 0.1 g. The density of air dried filler materialshall not be less than 19 lb/cu. ft. (304 kg/cu. m). The densityof oven dried fiber filler shall not be less than 18 lb/cu. ft. (288kg/cu.m).5.6 Water AbsorptionA standard expansion joint filler testspecimen with four sq

18、uare cut edges, when submerged hori-zontally under 1 in. (25 mm) of water at 70 6 5F (21.1 63C) shall absorb not more than 15 volume % in 24 h fornominal thickness of12 in. (13 mm) and over, and 20volume % for all other thicknesses.5.7 Asphalt ContentAt least 35.0 weight % of the finishedproduct sha

19、ll be asphalt uniformly distributed throughout thecross section of the material.6. Dimensions and Permissible Variations6.1 The preformed strips shall conform to the dimensionsspecified or shown on plans. Strips of joint filler that do notconform to the specified dimensions within the permissiblevar

20、iations of 6116 in. (61.6 mm) in thickness, 618 in. (63.2mm) in depth, and 614 in. (66.4 mm) in length shall berejected.7. Sampling7.1 Size and Number of SamplesEach sample shall consistof sufficient material to provide at least five test specimensmeasuring 412 by 412 in. (114 by 114 mm). One repres

21、entativesample, approximately two square feet, shall be selected fromeach shipment of 1000 square feet or fracture thereof.7.2 Individual samples are to be taken from separate sheetsof preformed expansion joint filler.7.3 Samples shall be packaged for transportation in such amanner that there will b

22、e no distortion or breakage of thematerial.8. Test Methods8.1 Determine the properties prescribed in this specificationin accordance with Method D 545.9. Rejection and Retest9.1 Material that fails to conform to the requirements of thisspecification shall be rejected. Rejection should be reported to

23、the manufacturer and supplier promptly and in writing. In caseof dissatisfaction with the test results, the manufacturer orsupplier may request retesting.10. Packaging10.1 Preformed expansion joint filler in sheets or stripsshould be stored and transported on pallets or suitable flatsurface to preve
