Designation:D 1190 97Standard Specification forConcrete Joint Sealer,Hot-Applied Elastic Type1This standard is issued under the fixed designation D 1190;the number immediately following the designation indicates the year oforiginal adoption or,in 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.Scope1.1 This specification covers joint sealants of the hot-pouredtype intended for use in sealing joints and cracks in portlandcement concrete and asphaltic concrete pavements.1.2 This standard does not purport to cover the propertiesrequired of sealants for use in areas of portland cementconcrete pavement subject to jet fuel or other fuel spillage,such as aircraft refueling and maintenance areas.1.3 The values in inch-pound units are the standard.2.Referenced Documents2.1 ASTM Standards:D 1985 Practice for Preparing Concrete Blocks for TestingSealants,for Joints and Cracks2D 5167 Practice for Melting of Hot-Applied Joint and CrackSealant and Filler for Evaluation2D 5249 Specification for Backer Material for Use withCold-and Hot-Applied Joint Sealants in Portland-CementConcrete and Asphalt Joints2D 5329 Test Methods for Sealants and Fillers,Hot-Applied,for Joints and Cracks in Asphaltic and Portland-CementConcrete Pavements23.General Requirements3.1 The joint sealant shall be composed of a mixture ofmaterials that will form a resilient and adhesive compoundcapable of effectively sealing joints in concrete against theinfiltration of moisture and foreign material throughout re-peated cycles of expansion and contraction with temperaturechanges,and that will not flow from the joint or be picked upby vehicle tires at summer temperature.The material shall becapable of being brought to a uniform application consistencysuitable for completely filling the joints without inclusion oflarge air holes or discontinuities and without damage to thematerial.4.Physical Requirements4.1 Pour Point shall be at least 20F(11C)lower than thesafe-heating temperature,which is the maximum temperatureto which the material may be heated and still conform to thisspecifications requirements.4.2 Cone Penetration,Non-immersed at 77F(25C),150g,5 s,shall not exceed 90.4.3 Flowat 140F(60C)shall not exceed 5 mm whentested for 5 h.4.4 Bond,Non-immersedThe sealant shall be tested at 0F(17.8C)for five complete cycles.The development at anytime during the test procedure of a crack,separation,or otheropening that at any point is over14in.(6.4 mm)deep,in thesealant or between the sealant and the concrete block,shallconstitute failure of the test specimen.The depth of the crack,separation,or opening shall be measured perpendicular to theside of the sealant showing the defect.At least two testspecimens in a group of three representing a given sample ofsealant shall meet this requirement for bond.5.Sampling and Heating5.1 Sampling5.1.1 Samples may be taken at the plant or warehouse priorto delivery or at the time of delivery,at the option of thepurchaser.If sampling is done prior to shipment,the inspectorrepresenting the purchaser shall have free access to the materialto be sampled.The inspector shall be afforded all reasonablefacilities for inspection and sampling which shall be conductedso as not to interfere unnecessarily with the operation of theworks.5.1.2 Samples shall consist of one of the manufacturersoriginal sealed containers selected at random from the lot orbatch of finished material.A batch or lot shall be considered asall finished material that was manufactured simultaneously orcontinuously as a unit between the time of compounding andthe time of packaging or placing in shipping containers.5.1.3 Obtain the sealant portion for testing from the selectedmanufacturers original sealed container in accordance withPractice D 5167.The sample portion added to and heated in themelter shall weigh 800 6 50 g.5.2 HeatingHeat the material in accordance with PracticeD 5167.5.2.1 The oil bath in the melter shall be heated to atemperature between the sealants safe heating temperature and75F(41.7C)above the sealants safe heating temperature.(Never allow the oil temperature to exceed 550F(288C).1This specification is under the jurisdiction of ASTM Committee D-4 on Roadand Paving Materials and is the direct responsibility of Subcommittee D04.33 onFormed-In-Place Sealants for Joints and Cracks in Pavements.Current edition approved May 10,1997.Published February 1998.Originallypublished as D 1190 52.Last previous edition D 1190 96.2Annual Book of ASTM Standards,Vol 04.03.1Copyright ASTM,100 Barr Harbor Drive,West Conshohocken,PA 19428-2959,United States.Add the sealant to the melter according to the instructions inPractice D 5167.After the sample has been added to the melter,regulate the oil temperature within the above listed temperature
