In order to construct master curve, a defined temperature is needed for calculations. The defining temperature, Td, is related to the glass transition temperature of the binder and is an indicator of the temperature dependency of the material. My question is how to get this temperature for different type of modified binders?
Keys: Binder, Modified binder, Polymer Binder, Rubber Binder, Asphalt, Bitumen
There is no need to obtain "defining temperature" Td to construct a master curve. For more information about Td, you can refer to “Alternate shift factor relationship for describing the temperature dependency of the viscoelastic behaviour of asphalt materials” in TRB 2011. And the book "Computer-Aided Design of Polymers and Composites, by D.
H. Kaelble, Marcel Dekker". You can find the fundamental information of master curve in my paper"Preparation and Properties of Nanoclay/TPS/Asphalt Ternary Binders" .
Dear Aval,

All the best

Siavash,
I believe that not is necessary the "Td" for construct the master curves, but, the "shift factors" are the tool for this.
Regards.
