ASTM D2170
KINEMATIC VISCOSITY OF ASPHALTS (BITUMENS).
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) in the range from 6 to 100 000 mm2/s (cSt).
