Heat Capacity of Bitumen

[19omalley90]

Hi everyone,

I'm looking for some help with a project which involves using steam to raise the temperature of bitumen in a pump.

I'm struggling to find any information on the heat capacity of bitumen and some other heat transfer info.

Can anyone tell me the following:

Melt point?
Heat Capacity?
Viscosity at room temp. and melt point?
Shear thinning stress?

Any help that you can offer is much appreciated!

Thanks very much.

Bitumens vary in quality (penetration bitumen, oxidized, hard grades, cutback. May be one of the following threads is helpful:

Inadvertently I pressed submit post, before I finished the message. There are three viscosity levels for bitumen grades:

[•]Maximum pumping viscosity = 2000 centistokes [cSt]
[•]Mixing viscosity = 150-300 cSt
[•]Spraying viscosity = 50-200 cSt

These viscosities vary with temperatures.

Good luck.
