D2170/D2170M−10 Standard Test Method for Kinematic Viscosity of Asphalts Bitumens

This standard is issued under the fixed designation D2170/D2170M; the number immediately following the designation indicates the year of original adoption or, in the case of revision, the year of last revision.

A number in parentheses indicates the year of last reapproval. A superscript epsilon (´) indicates an editorial change since the last revision or reapproval.

D2170/D2170M−10 Standard Test Method for Kinematic Viscosity of Asphalts Bitumens

Scope
1.1 This test method covers procedures for the determination of kinematic viscosity of liquid asphalts (bitumens), road oils and distillation residues of liquid asphalts (bitumens) all at 60°C [140°F] and of asphalt cements at 135°C [275°F] (Note 1) in the range from 6 to 100 000 mm2/s [cSt].

1.2 Results of this test method can be used to calculate viscosity when the density of the test material at the test temperature is known or can be determined.

See Annex A1 for the method of calculation.

NOTE 1—This test method is suitable for use at other temperatures and at lower kinematic viscosities, but the precision is based on determinations on liquid asphalts and road oils at 60°C [140°F] and on asphalt cements at 135°C [275°F] only in the viscosity range from 30 to 6000 mm2/s [cSt].

Significance and Use
5.1 The kinematic viscosity characterizes flow behavior.

The method is used to determine the consistency of bitumen as one element in establishing the uniformity of shipments or sources of supply. The specifications are usually at temperatures of 60 and 135°C.
