“…Goh et al found that adding nanoclays to asphalt could significantly reduce the potential for water damage of the mixture [18]. Similarly, Omar et al [5] and Ashish et al [19] also demonstrated that using nanoclays as modifiers is beneficial to the moisture resistance of asphalt. Although the majority of researchers confirmed that nanoclay has the potential to reduce moisture damage to asphalt, there are still researchers who hold different views.…”

“…In addition, it is worth mentioning that although the traditional methods have some limitations, they can be used to verify the results obtained from other tests [5]. Amongst the methods developed more recently are surface free energy (SFE) [19,33] and atomic force microscopy (AFM) [34,35].…”

Moisture susceptibility plays an important role in the damage of asphalt pavement. Failure occurs when asphalt is removed from the aggregate particles due to the decreased adhesion between the asphalt and aggregate in comparison with that between water and the aggregate. In recent years, efforts utilizing nanomaterials to improve the diverse properties of asphalt have proven to be effective. In this study, three types of nanoclays were used to modify styrene-butadiene-styrene- (SBS-) modified asphalt. The resistances to water damage of the modified binders were evaluated using the surface free energy (SFE) and atomic force microscopy (AFM). The results revealed that the total SFE decreased and the energy ratio (ER) increased when the asphalt binder was modified with the nanoclays, indicating that the addition of nanoclays can improve the moisture resistance of these aggregate-binder systems. After immersion, a decreased amount of bee structures was observed in both the SBS and nanoclay-modified asphalts due to the interactions between water and bitumen. However, the residual amount of bee structures was higher in the nanoclay-modified asphalts than in the SBS-modified asphalt, indicating that the addition of nanoclay makes the surface morphology of asphalt more resistant to water damage. Finally, freeze-thaw splitting tests were used to verify the results obtained through the SFE and AFM tests.

“…The effectiveness of both nanoclays and carbon nanotubes as reinforcing agents in asphalt binders and mastics has been assessed by many authors. In particular, it has been shown that these types of nanosized additives, if properly dosed and mixed with the base binder, may have a significant impact on viscoelastic properties, on the resistance to permanent deformation and on fatigue behaviour …”

The study presented in this paper aimed at evaluating the impact of different nanosized additives, including an organophilic nanoclay and multiwall carbon nanotubes, on the fatigue properties of dense‐graded asphalt mixtures. Cyclic direct tension fatigue tests were carried out, and the corresponding results were interpreted by means of a simplified version of the visco‐elastic continuum damage model. The experimental investigation also included linear viscoelastic characterization of the considered materials. Results derived from tests carried out on the mixtures containing nanosized additives were compared with those obtained for a reference standard mixture. It was found that the use of the abovementioned additives can give a substantial contribution to the enhancement of the fatigue damage resistance of asphalt mixtures. Moreover, when comparing the two types of additives, it was observed that organophilic nanoclays can outperform multiwall carbon nanotubes.
