Assessing creep properties of asphalt binder, asphalt mastic and asphalt mixture
In this article, creep properties of asphalt binders and asphalt mastics (binder filler composite) are tested in the Dynamic Shear Rheometer using a single shear creep test and considering steady-state flow conditions. These tests are performed for a set of 10 different asphalt binders and 18 corresponding asphalt mastics. The same material combinations are used to produce asphalt mixtures in the laboratory, which are then subjected to cyclic compression tests to assess the creep properties of the asphalt mixture. Finally, the creep properties resulting from asphalt binder tests, asphalt mastic tests and asphalt mixture tests are comparatively analysed in terms of the material-specific creep rates. The results show reasonable and sound correlations across the different material scales. The authors concluded that the asphalt binder has a significant impact on the creep behaviour of the corresponding asphalt mixture.
