2、 revision.A number in parentheses indicates the year of lastreapproval.A superscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope1.1 This test method covers procedures for the determina-tion of kinematic viscosity of liquid asphalts,road oils,anddistillation r
3、esidues of liquid asphalts all at 60 C 140 F andof liquid asphalt binders at 135 C 275 F(see table notes,11.1)in the range from 6 to 100 000 mm2/s cSt.1.2 Results of this test method can be used to calculateviscosity when the density of the test material at the testtemperature is known or can be det
4、ermined.See Annex A1 forthe method of calculation.NOTE1This test method is suitable for use at other temperatures andat lower kinematic viscosities,but the precision is based on determinationson liquid asphalts and road oils at 60 C 140 F and on asphalt bindersat 135 C 275 F only in the viscosity ra
5、nge from 30 to 6000 mm2/scSt.NOTE2Modified asphalt binders or asphalt binders that have beenconditioned or recovered are typically non-Newtonian under the condi-tions of this test.The viscosity determined from this method is under theassumption that asphalt binders behave as Newtonian fluids under t
6、heconditions of this test.When the flow is non-Newtonian in a capillarytube,the shear rate determined by this method may be invalid.Thepresence of non-Newtonian behavior for the test conditions can be verifiedby measuring the viscosity with viscometers having different-sized cap-illary tubes.The def
7、ined precision limits in 11.1 may not be applicable tonon-Newtonian asphalt binders.1.3 WarningMercury has been designated by the UnitedStates Environmental ProtectionAgency(EPA)and many stateagencies as a hazardous material that can cause central nervoussystem,kidney,and liver damage.Mercury,or its
