Rheometrics Framework Analysis to Capture Self-assemblies Organization in Bitumen Matrix
In this work, the liquid to solid transition of self-assemblies into bitumen matrix obtained with gelator additives is studied through rheometrics framework analysis. A very small amount of these organic compounds is able to harden bitumen and to shift the temperature range where they display solid-like behavior. Current test methods such as the softening point, the penetration needle test or the indentation depth are not sufficient to describe the gelling process of such soft matter. Rheometrics analysis are found to be more appropriate to rigorously determine the liquid to solid transition of the system as well as their mechanical properties. In opposite to the classical methods of characterization, the rheological experiments require a very small volume of sample, they are more sensitive and they give more information. Thanks to the sensitivity of rheometrics analysis, different temperatures can be identified such as the temperature of the Newtonian/viscoelastic transition and the temperature of the liquid/solid transition of pure or modified bitumen. Another advantage of rheometrical test is the characterization of the different viscoelastic behaviors of these materials with enlarged time spectrum.
