1.1 ,This test method covers procedures for the determination of the apparent viscosity of asphalt binder by vacuum capillary viscometers at 60 ,°,C [140 ,°,F]. It is applicable to materials having viscosities in the range from 0.0036 to over 20 ,000 Pa·,s [0.036 to over 200 ,000 P].
Note 1: ,This test method is suitable for use at other temperatures, but the precision is based on determinations on asphalt binders at 60 ,°,C [140 ,°,F].
