15、ocken, PA 19428-2959. United States14. Materials4.1 Sponge RubberThe joint filler shall consist of preformed strips of a durable, elastic sponge rubber compound, usingsynthetic rubber or natural rubber as a base and containing no reclaimreclaimed rubber or factice. Unless otherwise specified, thespo
16、nge 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 formed from cleangranulated cork particles securely bound together by a synthetic resin of an insoluble nature.4.3 Recycled
17、 PVCThe joint filler shall consist of preformed strips that have been extruded using scrap PVC material and usingeither no binder or a synthetic resin of an insoluble nature to securely bind it together. Unless otherwise specified, the recycled PVCshould have a cement gray color to blend with concre
18、te in appearance.4.4 Preformed strips of expansion joint fillers shall be of such character as not to be deformed or broken by ordinary handlingwhen exposed to atmospheric conditions. Pieces of the joint filler which have been damaged shall be rejected.5. Requirements5.1 Test SpecimenThe sample to b
19、e tested shall be cut from the sheet,sheet as manufactured, and shall be representative ofthe sheet stock.5.2 RecoveryThe test specimen shall be compressed to 50 % of its thickness before test. The load shall be releasedimmediately after application. At the end of 10 min after release of application
20、 of the load, the specimen shall have recovered toat least 90 % of its thickness before test.5.2.1 In case of failure to comply with the above requirements, the test specimen shall be given three applications of a loadsufficient to compress the material to 50 % of its thickness before test. The load
21、 shall be released immediately after eachapplication. At the end of 1 h after the third application, the specimen shall have recovered to at least 90 % of its thickness beforetest.5.3 CompressionThe load required to compress the test specimen to 50 % of its thickness before test shall be not less th
22、an50 nor greater than 1500 psi (0.34 to 10.35 MPa).5.4 ExtrusionThe test specimen shall be compressed to 50 % of its thickness before test, with three of the edges restrained.The amount of extrusion of the free edge shall not exceed 0.25 in. (6.4 mm).5.5 ExpansionIn the case of self-expanding cork (
23、Type III) expansion joint filler only, the test specimen, after being immersedin boiling water for 1 h, shall have a final thickness not less than 140 % of the thickness before test. Discoloration of the watershall not be considered an indication of failure.5.6 Boiling in Hydrochloric AcidIn the cas
24、e 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 beconsidered as failure. The test specimens shall be examined immediately after the end of the
25、 boiling period and shall be rejectedfor any of the following evidences of disintegration: (1) particles of cork dislodged during the boiling period, (2) specimen lacksresiliency, is very friable, and easily broken to pieces, or (3) surface of specimen appears porous and particles of cork are easily
26、dislodged by rubbing with fingers. Particles of cork dislodged from edges cut during preparation of the specimen should not beconsidered 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 shal
27、l not be lessthan 30 lb/ft3 (480 kg/m3).5.7.1 In the case of recycled PVC (Type IV) expansion joint filler only, the density by the dry unit weight test should air-drydensity shall not be less than 50 lb/ft3. (801 kg/m3).6. Dimensions and Permissible Variations6.1 The preformed strips shall conform
28、to the dimensions specified or shown on the plans. Strips of the joint filler which donot conform to the specified dimensions, within the permissible variations of +116 in. (1.6 mm) in thickness, 618 in. (3.2 mm)(3.2 mm) in depth,width, and 614 in. (6.4 mm) in length shall be rejected.7. Sampling7.1
29、 Size and Number of SamplesEach sample shall consist of sufficient material to provide at least five test specimensmeasuring 412 by 412 in. (114 by 114 mm). One representative sample, approximately 2 ft2, shall be selected from each shipmentof 1000 ft2 or fraction thereof.7.2 For self-expanding cork
30、 joint filler, a minimum of five 412 by 412 in. (114 by 114 mm) square specimens, properly bandedand 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 be no danger o
31、fdistortion or breakage.D1752 1828. Test Methods8.1 Determine the properties prescribed in this specification in accordance with Test Methods D545.9. Rejection and Retest9.1 Material that fails to conform to the requirements of this specification may be rejected. Rejection should be reported to them
32、anufacturer or supplier promptly and in writing. In case of dissatisfaction with the results of the test, the manufacturer or suppliermay request retesting.10. Packaging10.1 Preformed expansion joint filler in sheets or strips should be stored and transported on pallets or suitable flat surface topr
33、event 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 ofmoisture, and packaged in sizes convenient for handling on the job.11.
