Question

how to determine absolute viscosity of asphalt?​

Answer 1

Answer:

Viscosity Grade Bitumen (Asphalt) is a standard grade Bitumen usually used as a Paving Grade Bitumen suitable for road construction and for the production of asphalt pavements with superior properties. ... Viscosity Graded specifications covers bitumen (asphalt) graded by Viscosity at 60 C (140 °F).

Explanation:

Viscosity is simply a measure of a fluid's resistance to flow and is described by the following equation: Asphalt binder viscosity is typically measured at 60° C (140° F) because it approximates the maximum HMA pavement surface temperature during summer in the U.S.
