In recent months the use of zero shear viscosity has been considered as a
possible specification parameter for asphalt binders replacing the current
G*/sin delta. This parameter can be approximated to the steady state
viscosity for linear visco-elastic liquids thus making it possible to obtain
a good estimation of the ZSV from DSR data. The analysis procedure is very
fast and easy to implement. A shareware software has been released by
Abatech to allow the computation of the ZSV in this manner. The software
and background information is available from
http://www.abatech.com/rheazsv.htm. The software uses a small text file
generated from a frequency sweep at a single temperature. We would be very
interested to hear discussion from anyone who tries this procedure.
Please feel free to pass this e-mail on to your own mailing lists and
friends in the industry.
Kind regards
