“…Although very similar features between Elvaloy and SBS copolymer could be observed on the master curves of dynamic material functions, their origin is completely different. The presence of oxirane in Elvaloy promotes a reaction with polar asphalt components, which enhances the stiffness of modified asphalt [48][49][50]. The formation of asphaltene-Elvaloy complexes depends on the amount of functional groups present in asphalt as well as Elvaloy.…”

The new class of reactive polymers is designed to modify asphalt through chemical reactions with asphalt components. The complexity of such systems and the long experience with thermoplastic elastomers as well as with some other “classical” modifiers, and to a degree that our present testing methods and even specifications revolve around these materials, might obscure the fact that we are dealing with rather different modification systems and possibly with new emerging asphalt paving technologies. Our present work attempted to compare two different reactive polymer systems with the “classical” system which uses thermoplastic elastomer. The impact of reactive polymer systems on asphalt was studied through material properties manifested by specification tests and through the development of thermo-rheological properties in linear and non-linear viscoelastic regions. As expected, the behavior of reactive polymeric systems with different chemistries also differed among themselves. The available results showed that the reactive groups of polymers react with polar components of asphalt leading to higher stiffness at elevated pavement temperatures and differing impact on low temperature properties. The data point to a significantly improved resistance to plastic deformation of pavement in the case of reactive polymers, despite the fact that elastic recovery-based specification tests failed to identify this improvement.

“…12 As essentially the waste material at the bottom of the refinery stack, asphalt binder's nanoscale properties are only now being investigated; its surface properties as measured with AFM have been linked to its bulk properties. 7,8,13,14 Figure 1B is a plot of the exponential growth in publications containing the search terms 'Atomic Force Microscopy' and 'Asphalt' over the last two decades. No doubt there are many new AFM users behind this accelerating expansion in research.…”

Atomic force microscopy (AFM) is based upon a simple operational principle. However, the presentation and interpretation of AFM images can easily suffer from consequential artefacts that are easily overlooked. Here we discuss results from AFM and its companion variations AFM‐IR (AFM combined with infrared spectroscopy) and PF‐QNM (an AFM mode called peak‐force quantitative nano‐mechanical mapping) by imaging ‘bee’ structures in asphalt binder (bitumen) as examples. We show how common problems manifest themselves and provide solutions, with the intent that authors can present their results clearly and avoid interpreting artefacts as true physical properties, thereby raising the quality of AFM research.
