Master curves construction for viscoelastic functions of bituminous materials
Applied RheologyThe performance of bituminous materials is often evaluated using rheological properties measured within the linear viscoelastic region. If there is a univocal temperature dependence of all the relaxation times, data obtained in different operating ...

Creep or Relaxation Master Curves Calculated from Experimental Dynamic Viscoelastic Function [PDF]
Science and Engineering of Composite Materials, 1998 The problem treated consists in obtaining the unknown creep or relaxation master curves from experimental dynamic viscoelastic functions obtained on a DMTA analyser. In the present work, a general discrete model, the generalised Kelvin model or the generalised Maxwell model, is used to fit the complex compliance or the complex modulus, respectively.

Rubber Chemistry and Technology, 2012 ABSTRACT One of the important aspects in the development of new tire compounds is the correlation between the dynamic mechanical properties of the rubber, measured on a laboratory scale, and the actual tire performance. The measuring protocol for dynamic mechanical properties with high precision and good correlation with tire properties is ...
