Moisture sensitivity of asphalt mixtures may cause damage due to cohesion in asphalt binder membrane and adhesion between aggregate and asphalt binder that result in considerable damage to the pavements. Therefore, by determining the adhesion quality in a modified aggregate-asphalt binder system, one can choose the suitable material compositions to decrease the moisture sensitivity of mixtures. In this study, the effects of modified asphalt binder with carbon nanofiber and modified aggregates with carbon nanotube on the moisture sensitivity of asphalt mixtures were simultaneously explored. For investigating the moisture sensitivity, the indirect tensile strength test and surface free energy concept were implemented. The results of the indirect tensile strength test revealed that modification of asphalt binder and aggregates with carbon nanofiber and carbon nanotube, respectively, increased the indirect tensile strength and tensile strength ratio values of mixtures. The results of surface free energy indicated that using carbon nanofiber and carbon nanotube enhanced the adhesion free energy of the aggregate-asphalt binder system. Moreover, utilizing carbon nanofiber to modify asphalt binder enhanced the cohesion free energy values in the asphalt binder membrane. Also, carbon nanofiber and carbon nanotube brought detachment energy of the system toward zero, indicating less desire for the mixtures to be stripped. Generally, investigations performed by the two methods showed that covering aggregates by carbon nanotube as well as utilizing carbon nanofiber as an asphalt binder modifier had a positive impact on decreasing moisture sensitivity of asphalt mixtures.

“…Saleh studied the effect of adding the different ratios of asphaltene to Begi and Qayara asphalt [22]. He measured the rheological properties, and the results obtained after 18 months of aging, compared with those of untreated asphalt, showed an increase in the homogeneity system for both Qayara and Begi asphalt, with improvement in the aging specifications for Qayara asphalt only [23][24][25]. Anjan and Veeragavan found that the mixing of asphalt with certain additives caused to improve the mechanical properties of the studied asphalt [26].…”

This study focuses on producing asphalt with improved rheological properties that differ from the original asphalt and are less affected by aging conditions. The rheological properties of Qayara asphalt were enhanced by modifying the asphalt using spent rubber tire (SRT) with different percentages of anhydrous aluminum chloride. Percentages ranging from 1.0% by weight of the spent tire rubber were added after proceeding with the thermal crushing process. The percentages of anhydrous aluminum chloride catalyst were 0.4 and 0.8%, respectively. This mixture was microwaved at 270 watt of power for 4, 8, and 12 min, respectively. The measurements performed are plasticity, penetration, softening point, and penetration index. The previously mentioned measurements were also made on the modified asphalt one year after the modification process to understand the effect of aging conditions. The microstructure and thermodynamics have been characterized by FE-SEM and EDX measurements. This study provides good rheological properties of the modified bitumen binder that is aging-resistant.

Moisture damage is one of the most critical distresses affecting asphalt pavement. The use of mineral fillers such as hydrated lime can increase the moisture resistance of the asphalt mixtures. In this study, the effects of hydrated lime (HL) and nano hydrated lime (NHL) were investigated on the moisture susceptibility of modified asphalt mixtures. The asphalt mixtures were modified using HL and NHL with varying percentages of each additive. The indirect tensile strength (ITS) test was performed to investigate moisture susceptibility. This test was carried out with three types of asphalt mixtures including, normal asphalt mixture without additives, modified asphalt mixture with HL, and modified with NHL. The results showed that the addition of HL and NHL as mineral fillers enhanced the performance of the mixtures against moisture damage. The highest increase in ITS value under dry conditions was observed in the modified mixtures with 20% HL and 20% NHL, and under wet conditions it was observed at 30% HL and 20% NHL. The results also indicated that the addition of 20% HL and 30% NHL increased the value of tensile strength ratio (TSR) by 78.6% and 70.6%, respectively.
