1、Designation: D 6297 01 (Reapproved 2007)Standard Specification for Asphaltic Plug Joints forBridges1This standard is issued under the fixed designation D 6297; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last revisi
2、on. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.1. Scope1.1 This specification covers the material, testing and appli-cation requirements for a field molded asphaltic plug joint(APJ) used
3、in expansion joint sealing on asphalt concreteoverlay and portland cement concrete decks. The scope of thisspecification is limited to field molded APJ. This moldedelement can consist of multilayer, or single layer, or both,application systems depending upon individual manufacturingrequirements. The
4、 details of this specification are limited to thematerials used in the application of APJ. It is recommendedthat a practical means of testing the watertightness aspects ofthe individual systems, either in the field or at the testinglaboratory, be developed. When used on highway bridges,limits on max
5、imum joint movements shall be specificallyidentified for each type of APJ. APJs should not be used formovement applications exceeding 6 25 mm from the installa-tion width.1.2 The values stated in SI units are to be regarded as thestandard. The values given in parentheses are provided forinformation
6、only.1.3 This standard does not purport to address all of thesafety concerns, if any, associated with its use. It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2. Referen

Dimensions and Tolerances6.1 The size, shape, and dimensional tolerance shall beagreed upon by the purchaser and t
16、he producer or supplier.These tolerances shall be in compliance with the field construc-tion specifications. The standard minimum blockout dimen-sions are 50 3 500 mm; however, it should be noted that valuesfluctuate depending on existing field conditions.7. Procedure7.1 The AB shall be heated to a
17、temperature as specified bythe manufacturer. The melter must be supplied with a continu-ous agitation system and calibrated thermometers.7.2 The specified aggregate shall be heated to the manufac-turers prescribed temperature in a manufacturers recom-mended mixer. The temperature of the specified ag
18、gregate shallbe controlled by a digital temperature sensor.7.3 The AB shall be blended with the heated aggregate at aratio of aggregate to AB as specified by the manufacturer. Theblend tolerance shall be 65 % by weight. The minimumaggregate content shall be 68 % by weight.7.4 Alternately, the AB and
19、 specified aggregate can bepre-measured and pre-packaged, heated on site in a manufac-turers recommended mixing unit.7.5 The specified aggregate shall be coated completely withbinder prior to placement in the blockout.7.6 The closed cell, foam expansion joint filler shall beplaced into the expansion
20、 gap at a depth of not greater than thewidth of the gap. Where the gap is greater than 25 mm, theminimum depth shall be 25 mm. The joint opening shall thenbe filled with AB until it runs into the corresponding blockoutto ensure a water-tight joint below the bridging plate.7.7 The bridging plate shal
21、l be mild steel or aluminum aminimum of 6-mm thick and 200-mm wide, cut in minimum1.2-m lengths, centered over the entire length of the expansionjoint gap when specified. When specified, the bridging plateshall have pre-drilled holes at 300-mm on center for thelocating pins.7.8 The blended heated AB
22、 and heated specified aggregateshall be placed in a prepared blockout in accordance with themanufacturers recommended installation procedures.7.9 When specified, the locating spikes used to position thebridging plate, shall be galvanized 16 d column nails or larger.7.10 The blended heated AB and hea
23、ted coated specifiedaggregate shall be compacted longitudinal and transverse to thejoint using a roller or plate compactor, which delivers aminimum centrifugal force of 15 kN.7.11 Where an antiskid/antitracking surface is required, thesurface of the APJ shall be heated prior to broadcasting theantis
24、kid material in accordance with the manufacturers writteninstructions.8. Sampling8.1 A batch shall consist of a maximum 19 100 kg, of thethermoplastic polymeric modified asphalt.

Test MethodsLow Temperature Cone Penetration, Nonimmersed9.1 Apparatus:9.1.1 Penetrometer/ConeConduct this test using the ap-paratus descr
28、ibed in Test Method D 5, except as specifiedherein. Use a penetration cone in place of the standardpenetration needle. The cone shall conform to the requirementsgiven in Test Methods D 217, except the interior constructionmay be modified as desired. The total moving weight of thecone and attachments
29、 shall be 150.0 6 0.1 g.9.1.2 Cold Chamber The cold chamber shall be capableof maintaining the required cold test temperature within 61.1C.9.2 Specimen PreparationPour a portion of the AB pre-pared in accordance with Practice D 5167 into three 177-mLtins measuring approximately 69-mm diameter and 44
30、 mm indepth and fill flush to the rim of each tin.
