ABSTRACT
At constant strain amplitude, obtained results are qualitatively similar for bitumen and mastic. Three phases are identified during the tests. In the first phase, measured LVE G* complex moduli remains very close to the G* (LVE) master curve of the undamaged material. It indicates that, in this phase, the decrease of G* could be explained only by an “equivalent” heating. Yet, the increase of temperature of the material, which is measured by an inner sensor, cannot explain entirely the decrease of G*. Another phenomenon, such as thixotropy, should occur. During the second phase, the decrease of G* does not remain on master curve. This decrease is probably due to micro-cracking damaging. It corresponds to a phase with rather stable temperature. At the beginning of the third phase, macro cracks appear and develop in the sample. As the sample is no more homogeneous, this phase cannot be easily interpretable.
