A number in pa
2、rentheses 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 in expansion joint
3、 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 details of this s
4、pecification 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 maximum joint movemen
5、ts 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 only.1.3 This stan
6、dard 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.

16、nce 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 temperature as specified bythe manufacturer. The melter must
17、 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 aggregate shallbe controlled by a digital temperature sensor.7
18、.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 specified aggregate can bepre-measured and pre-packaged, he
19、ated 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 gap at a depth of not greater than thewidth of the gap. Whe
20、re 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 shall be mild steel or aluminum aminimum of 6-mm thick and 200-m
21、m 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 and heated specified aggregateshall be placed in a prepared
