The research on rheology and the mechanical modelling of complex, non-linear plastic-viscoelastic materials is continuing at the Department of Ceramics and Silicates Engineering (University of Miskolc) since, a 30 years collaboration of the associates of the world-famous University of Civil Engineering Moscow [8, 9, 10, 11], and also leaning on our own situations and opportunities [12, 13, 14, 15].
In these days is also used the Burgers model in asphalt rheology, but in 2005 a new rheological model for asphalt was created by the associates of the Department of Ceramics and Silicate Engineering, which describes effectively and precisely the physical and mechanical processes in asphalt concretes and in asphalt mixtures made with bitumen [21, 22, 25].
Shear tests of asphalt mixtures A Combined Rheo-tribometer instrument was successfully developed and patented by the coworkers of the Department of Ceramics and Silicate Engineering at the University of Miskolc [24] (Fig. 3.a) Fig. 3.a and 3.b.
