Overview
PT-D445-3007 Asphalt Kinematic Viscosity Apparatus measures absolute viscosity of viscosity graded paving bitumen (IS: 73: 2006) at 60 C in accordance with IS: 1206 (Part II) (similar to ASTM D 2171), which uses a vacuum capillary viscometer. It should be noted that any other viscometer such as rotational viscometer
Cannot be used to measure the absolute viscosity at 60 C since the bitumen in nonNewtonian in nature at this temperature. While obtaining quotations specify the following requirements. Although Asphalt Institute vacuum viscometer and Modified Koppers vacuum viscometer can also be used, the following refers to Cannon-Manning vacuum viscometer only.
