3、. SCOPE 1.1. This specification covers preformed expansion joint fillers having relatively little extrusion and substantial recovery after release from compression. 1.2. The values stated in SI units are to be regarded as the standard. Note 1Attention is called to M 153 and to M 33. 2. REFERENCED DO
4、CUMENTS 2.1. AASHTO Standards: M 33, Preformed Expansion Joint Filler for Concrete (Bituminous Type) M 153, Preformed Sponge Rubber and Cork Expansion Joint Fillers for Concrete Paving and Structural Construction T 42, Preformed Expansion Joint Filler for Concrete Construction 3. ORDERING INFORMATIO
5、N 3.1. Products conforming to this specification are manufactured in sheet form to a range of thicknesses; namely, 6.4, 9.5, 13, 19, and 25 mm. Sheet sizes may be 900 or 1200 mm in width and standard length of 3 m. Purchaser must specify sheet sizes when ordering. 3.2. Joint filler in strip form is
6、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. 4. MANUFACTURE 4.1. This product shall consist of preformed sheets or strips made of one of the following: 4.
7、1.1. Cane or other suitable fibers of a cellular cellulosic nature securely bound together and then uniformly saturated with asphalt; 4.1.2. Strips formed from clean granulated cork securely bound together by a suitable asphalt binder and encased between two layers of saturated felt or two layers of
8、 glass-fiber felt; or 2015 by the American Association of State Highway and Transportation Officials.All rights reserved. Duplication is a violation of applicable law.TS-4e M 213-2 AASHTO 4.1.3. Strips of a durable composite of ground recycled rubber from automobile tires bonded together with a poly
9、urethane adhesive. 4.2. Preformed strips of expansion joint filler shall be of such character as not to be deformed or broken by twisting, bending, or other ordinary handling when exposed to atmospheric conditions. 5. REQUIREMENTS 5.1. Test SpecimenThe sample to be tested shall be cut from the sheet
10、, as manufactured, and shall be representative of the sheet stock. 5.2. CompressionThe load required to compress the test specimen to 50 percent of its thickness before test shall be not less than 690 kPa and not more than 5200 kPa. If the nominal thickness of the specimen is less than 13 mm, a maxi
11、mum load of 8600 kPa will be permitted. The sample after compression shall not show a loss of more than 3 percent of its original mass. 5.3. ExtrusionThe test specimen shall be compressed to 50 percent of its thickness before the test with three of its edges restrained. The amount of extrusion of th
12、e free edge shall not exceed 6 mm. 5.4. 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 the 10 min after release of application of the load, the specimen shall have recovered to at l
13、east 70 percent of its thickness before the test. 5.4.1. 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 percent of its thickness before the test. The load shall be released immediately
14、after each application. At the end of 1 h after the third application, the specimen shall have recovered to at least 70 percent of its thickness before the test. 5.5. DensityFor fiber joint only, oven dry the specimen at 104 3C for 2 h or to a constant weight. After oven drying, cool the specimen to
15、 room temperature in a covered desiccator and weigh to the nearest 0.1 g. The density of air-dried filler material shall not be less than 304 kg/m3. The density of oven-dried fiber filler shall not be less than 288 kg/m3. 5.6. Water AbsorptionA standard expansion joint filler test specimen with four
16、 square cut edges, when submerged horizontally under 25 mm of water at 21 3C, shall absorb not more than 15 percent by volume in 24 h for nominal thickness of 13 mm and over, and 20 percent by volume for all other thicknesses. 5.7. Asphalt ContentFor materials manufactured as described in Sections 4
17、.1.1 and 4.1.2, at least 35 percent by mass of the finished product shall be asphalt uniformly distributed throughout the cross section of the material. 6. DIMENSIONS AND PERMISSIBLE VARIATIONS 6.1. The preformed strips shall conform to the dimensions specified or shown on the plans. Strips of the j
18、oint filler that do not conform to the specified dimensions, within the permissible variation of 1.5 mm in thickness, 3 mm in depth, and 6 mm in length, shall be rejected. 2015 by the American Association of State Highway and Transportation Officials.All rights reserved. Duplication is a violation o
19、f applicable law.TS-4e M 213-3 AASHTO 7. SAMPLING 7.1. Size of SamplesEach sample shall consist of sufficient material to provide at least five test specimens measuring 114 by 114 mm. One representative sample, approximately 200 mm2, shall be selected from each shipment of 100 m2or fraction thereof.
20、 7.2. Individual samples are to be taken from separate sheets of preformed expansion joint filler. 7.3. Samples shall be packaged for transportation in such a manner that there will be no danger of distortion or breakage. 8. TEST METHODS 8.1. Determine the properties prescribed in this specification
21、 in accordance with T 42. 9. REJECTION AND RETEST 9.1. Material that fails to conform to the requirements of this specification shall be rejected. Rejection should be reported to the manufacturer and supplier promptly and in writing. In case of dissatisfaction with the test results, the manufacturer
22、 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 surface to prevent breakage and permanent deformation. 11. KEYWORDS 11.1. Bituminous; expansion joint; filler; joint; preformed. 2015 by the American Association of State Highway and Transportation Officials.All rights reserved.
