1、Designation: D 2835 89 (Reapproved 2007)Standard Specification forLubricant for Installation of Preformed Compression Sealsin Concrete Pavements1This standard is issued under the fixed designation D 2835; the number immediately following the designation indicates the year oforiginal adoption or, in
2、the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the Department of Defense.1. Scope*1.1 T
3、his specification covers a lubricant suitable for facili-tating the insertion and positioning of preformed elastomericcompression seals in prepared voids (usually contractionjoints) in concrete pavement.1.2 The requirements of the lubricant are based on theperformance of the lubricant as measured by
4、 its solids content,homogeneity, consistency and drying rate.1.3 The values stated in inch-pound units are to be regardedas the standard. The metric equivalents of U.S. customary unitsmay be approximate.1.4 The following precautionary caveat pertains only to thetest method portion, Section 7 of this
5、 specification. Thisstandard does not purport to address all of the safety concerns,if any, associated with its use. It is the responsibility of the userof this standard to establish appropriate safety and healthpractices and determine the applicability of regulatory limita-tions prior to use.2. Ref

Classification3.1 The lubricant shall be based on polychloroprene, con-taining only soluble phenolic resins blended together withantioxidants and acid accepto
7、rs in a suitable mixture of organicsolvents.4. Requirements4.1 HomogeneityThe lubricant shall be uniform and con-tain no lumps or agglomerates.4.2 Solids ContentThe nonvolatile content of the lubri-cant shall be no less than 24.0 weight %.4.3 ConsistencyThe lubricant shall exhibit a viscosity inone
8、of the following ranges:4.3.1 Type Ifor hand or machine application, 3000 to8000 cP.4.3.2 Type IIfor machine application, 8000 to 15 000 cP.4.4 Drying RateA bond between lubricant-coated papersprepared after 8-min drying time shall separate completely inless than 10 s when a 50-g load is applied in
9、shear. A similarbond prepared after 20-min drying time shall remain unsepa-rated for a minimum of 10 s when a 50-g load is applied inshear.5. Basis of Purchase5.1 Each lot of lubricant shall be accompanied by themanufacturers certified test results attesting compliance withthis specification, unless
10、 an alternative agreement is concludedby the manufacturer and the purchaser.6. Sampling6.1 The lubricant samples shall be a 1-quart (1-litre) aliquotconsisting of a composite taken when possible from three ormore separate containers chosen at random. Samples also shallbe taken from containers which
11、appear to be nonrepresentativeand shall be tested separately. Before a sample is withdrawn,the contents in the container shall be mixed to uniformconsistency. The sample shall be placed immediately in anairtight-glass jar or metal can until tested.7. Test Methods7.1 HomogeneityStir the test sample b

(0.38 mm) shall notbe considered cause for rejection.1This specification is under the jurisdiction of ASTM Committee D04 o

(3 by 25 by50-mm).7.4.2 Procedure:7.4.2.1 Condition the lubricant for at least3hat73.4 63.6F (23 6 2C). Apply a series of 2 in. wide (wet thickness)(14 6 2.5-mils) 0.356 6 0.0
19、64-mm films of the lubricant tofour separate nonabsorbent paper surfaces. A film applicator asspecified in 7.4.1.1 has been found to produce a wet film in thespecified range with this class of materials, but the depositedfilm thickness from any specific spreader and lubricant systemshould be checked
20、 to determine the conformance to thespecified thickness. Films should be at least 4 in. (100 mm)long, centered on the paper and parallel to the long axis of thesheet. Allow to dry in a horizontal position in a draft-free area.The time upon completion of the casting of the second film ofeach pair cas
21、t is recorded as the initial drying time for that pairof films.7.4.2.2 After several minutes drying, cut off at least 112 in.(40 mm) from the bottom of the cast films and discard. Afterdrying 8 min overlap the cut edges of the first pair 1 in. andplace face-to-face to form a 1 by 2-in. area lap shea
22、r bond.Take care to align the two films so that a force applied alongtheir center lines will impose a direct shear force without atwisting movement. Form the bond by placing the overlappedpapers on a horizontal smooth surface, placing a18-in. thick, 1by 2-in. aluminum plate over the bond area, and p
23、lacing a 500g laboratory weight on this plate for 10 s. Hang the bondedpieces immediately in a vertical position and attach a 50-gweight with a small loop of wire, weighing less than 1 g, to thelower piece of paperboard forming the bond.Align the point ofsupport and the point of attachment for the w
24、eight on the centerlines of the cast films.7.4.2.3 Record the time needed for the 50-g load to com-pletely separate the bonded pieces with the aid of a stop watch.If separation is not complete in 1 min, discontinue the test andrecord the separation time as more than 1 min.7.4.2.4 Repeat the above pr
25、ocedure with a pair of cast filmswhich are allowed to dry for 20 min before forming a bond.7.4.2.5 Testing should be conducted at 73.4 6 3.6F (23 61C) and at a relative humidity of 50 6 5%.8. Precision and Bias8.1 No statement is made about either the precision or biasof this specification for measu
