6、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 tha
7、t 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
8、.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.
9、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 betw
10、een 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 mee

12、erialto 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 fro
13、m 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
14、 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 th
