Products conforming to this specification are manufactured in sheet form to a range of thicknesses: namely, 6, 9.5, 13, 19, and 25 mm. Sheet sizes may be 900 or 1200 mm in width and in lengths of 900, 1500, 1800, 30
6、00, or 3700 mm. Purchaser must specify sheet sizes when ordering. 3.2. Joint filler in strip form is cut from the sheets as manufactured. When ordering joint filler strips, the purchaser must specify thickness, width, and length; strip widths are available from 50 mm in increments of 13 mm. 2016 by

Sponge RubberThe joint filler shall consist of preformed strips of a durable, elastic sponge rubber compound, using synthet
8、ic rubber or natural rubber as a base and containing no reclaimed rubber or factice. Unless otherwise specified, the sponge rubber shall have a cement gray color to blend with concrete in appearance. 4.2. Cork and Self-Expanding CorkThe joint filler shall consist of preformed strips that have been f
9、ormed from clean granulated cork particles securely bound together by a synthetic resin of an insoluble nature. 4.3. Polyurethane-Bonded Recycled RubberThe joint filler shall consist of preformed strips of a durable composite of ground recycled rubber from automobile tires bonded together with a pol
10、yurethane adhesive. 4.4. Preformed strips of expansion joint fillers shall be of such character as not to be deformed or broken by ordinary handling when exposed to atmospheric conditions. Pieces of the joint filler that have been damaged shall be rejected. 5. PHYSICAL REQUIREMENTS 5.1. Test Specime
11、nThe sample to be tested shall be cut from the sheet as manufactured and shall be representative of the sheet stock. 5.2. RecoveryThe test specimen shall be compressed to 50 percent of its thickness before the test. The load shall be released immediately after application. At the end of 10 min after
12、 release of the application of the load, the specimen shall have recovered to at least 90 percent of its thickness before the test. 5.2.1. In case of failure to comply with the above requirements, the test specimen shall be given three applications of a load sufficient to compress the material to 50
13、 percent of its thickness before the test. The load shall be released immediately after each application. At the end of 1 h after the third application, the specimen shall have recovered at least 90 percent of its thickness before the test. 5.3. CompressionThe load required to compress the test spec
14、imen to 50 percent of its thickness before the test shall be not less than 340 nor greater than 10 350 kPa. 5.4. ExtrusionThe test specimen shall be compressed to 50 percent of its thickness before the test with three of the edges restrained. The amount of extrusion of the free edge shall not exceed
15、 6 mm. 5.5. ExpansionIn the case of self-expanding cork (Type III) expansion joint filler only, the test specimen, after being immersed in boiling water for 1 h, shall have a final thickness not less than 140 percent of the thickness before the test. Discoloration of the water shall not be considere
16、d an indication of failure. 5.6. Boiling in Hydrochloric AcidIn the case of cork and self-expanding cork (Types II and III) expansion joint fillers only, the test specimen shall show no evidence of serious disintegration. Discoloration or a small amount of swelling shall not be considered as failure
17、. The test specimens shall be examined immediately after the end of the boiling period and shall be rejected for any of the following evidences of disintegration: (1) particles of cork are dislodged during the boiling period (Note 2); (2) the specimen lacks resiliency, is very friable, and is easily
18、 broken to pieces; or (3) the surface of the specimen appears porous and particles of cork are easily dislodged by rubbing with fingers. 2016 by the American Association of State Highway and Transportation Officials.

19、HTO Note 2Particles of cork dislodged from edges cut during preparation of the specimen should not be considered as constituting failure under this requirement. 5.7. DensityIn the case of sponge rubber (Type I) expansion joint filler only, the density of the air-dry filler shall be not less than 480
20、 kg/m3. 6. DIMENSIONS AND PERMISSIBLE VARIATIONS 6.1. The preformed strips shall conform to the dimensions specified or shown on the plans. Strips of the joint filler that do not conform to the specified dimensions, within the permissible variations of 1.5 mm in thickness, 3 mm in depth, and 6 mm in
21、 length, shall be rejected. 7. SAMPLING 7.1. Size and Number of SamplesEach sample shall consist of sufficient material to provide at least five test specimens measuring 114 by 114 mm. One representative sample, approximately 0.2 m2, shall be selected from each shipment of 100 m2or fraction thereof.
22、 7.2. For self-expanding cork joint filler, a minimum of five 114-by-114-mm square specimens, properly banded and plastic-wrapped at the point of manufacture, shall be submitted for testing. 7.3. Samples shall be packaged for safe transportation to the testing agency in such a manner that there will
23、 be no danger of distortion or breakage. 8. TEST METHODS 8.1. Determine the properties prescribed in this specification in accordance with T 42. 9. REJECTION AND RETEST 9.1. Material that fails to conform to the requirements of this specification may be rejected. Rejection should be reported to the
24、manufacturer or supplier promptly and in writing. In case of dissatisfaction with the results of the test, the manufacturer or supplier may request retesting. 10. PACKAGING 10.1. Preformed expansion joint filler in sheets or strips should be stored and transported on pallets or a suitable flat surfa
25、ce to prevent breakage and permanent deformation due to weather conditions. 10.2. Self-expanding cork filler shall be wrapped in waterproof paper, sealed in a manner that will prevent the entrance of moisture, and packaged in sizes convenient for handling on the job. 11. KEYWORDS 11.1. Construction;
26、 cork; expansion; joint; paving; preformed; rubber; sponge; structural. 1Except for the Type IV Polyurethane-Bonded Recycled Rubber Joint Filler and any reference to Type IV, this specification agrees with ASTM D1752-04a. 2016 by the American Association of State Highway and Transportation Officials.
