WebGenerally, bitumens follow the so-called time-temperature superposition principle, where time, or frequency, and temperature have a similar impact on the material. This concept is widely used in other areas like in the polymer field. Master curves play a key role in the rheological analysis of bitumens.

Fluids are diﬀerent from solids, because ﬂuids continuously deform when there is an applied stress, as shown in ﬁgure 1(b), while solids deform and then stop, as shown in ﬁgure 1(a). Solids are said to have an ‘elastic’ response, and can resist rubber applications for dredging
