“…In the case of Source20, it should be highlighted that it presented the lowest ER value among the PG 76-22 asphalt-binders tested and also yielded the highest CoV (10.42%) value, that is, had the highest variability. is could have been probably due to the presence of cellulose fibers that may have chemically interacted with the chlorinated solvent during the extraction process, thus impacting the ER results, in terms of both the ER magnitude and data variability [44,45].…”

This study was conducted to quantitatively and statistically evaluate the effects of material source on the ductility of asphalt-binders, measured in terms of the elastic recovery (ER) property. The ER data used in the study were excerpted from the Texas flexible pavements and overlays database, namely, the Texas Data Storage System (DSS), covering plant-mix extracted PG XX-22 asphalt-binders (i.e., rolling thin film oven (RTFO) residues) from 20 different sources and measured using the Ductilometer test at 10°C. The findings of the study indicated that material source has an impact on the ER property of asphalt-binders. Statistically significant differences were observed among some sources and suppliers that reported the same low-temperature asphalt-binder type/grade (i.e., PG XX-22). Overall, the study contributes to enriching the literature on the material-source effects on asphalt-binders’ ER properties, consistency, variability, and data quality. In particular, the study highlights the sensitivity nature of the asphalt-binder ER parameter to material-source effects.

“…And the high-temperature grade for Z70 and Z60 would be PG 70-XX. From the high-temperature rutting resistance perspective, the RTFOT-aged original asphalt Z40, Z50, Z60, and Z70 were found to be significantly better than the Pen 70 # and WBA asphalt as theoretically expected [33]. In general, aged asphalt is more prone to cracking at low temperatures due to the evaporation and degradation of the saturates and aromatic components [17,22].…”

Reclaimed asphalt pavement (RAP) material is generally under a large amount of aged asphalt coated on the surface of the aggregates, which often limits its (RAP) wide application. Bioasphalt is a renewable material with constituent components that are comparable to regular petroleum asphalt and has the potential to rejuvenate the performance of the aged asphalt in RAP materials. In this laboratory study, the optimum bioasphalt dosage for rejuvenating and optimizing warm-mix rejuvenated bioasphalt (WBA) performance, in the presence of styrene-butadiene-styrene (SBS) and naphthenic oil additives, was investigated. The laboratory test results of the single-factor and orthogonal experiment indicated that the optimal dosage of bioasphalt in WBA was 30% at 4% SBS and 10% naphthenic oil, respectively. The test results further indicated that the WBA’s ductility properties were highly responsive to the bioasphalt dosage. Naphthenic oil, on the other hand, had the greatest impact on the WBA fluidity. Likewise, the Brookfield viscosity experimentation showed that the fluidity of WBA and aged asphalt with different contents at 30%, 40%, 50%, 60%, and 70%, respectively, satisfactorily met the Chinese construction requirements. The adhesion test indicated excellent adhesion and good moisture stability properties for WBA. The resultant PG grades of WBA blended with 40% and 70% aged asphalt were PG 64-34 and PG 70-22, respectively. Microstructure and surface morphology analysis showed carbonyl absorption peaks with high rejuvenation and surface-crack repair potential for the WBA over the control asphalt that was evaluated in the study.

“…The spacing between the parallel plates was 2 mm. In the study, the DSR test was conducted at a temperature of 20°C in a controlled stress‐loading mode at 0.4 MPa 30,31 . Like the RTFOT and PAV aging tests, four SRAA sample replicates were prepared and tested in the DSR test device per rejuvenation dosage.…”

To improve the self-healing properties and reduce the reaction energy barrier during the self-healing process of aged asphalt-binders, this study utilized residual oil extracted from soybean to regenerate the aged asphalt-binder and enhance its rheological properties including the self-recovery potential. The self-healing properties from the reaction energy barrier and chemical structure were characterized using molecular dynamic simulations. In addition, the rheological properties were measured and quantified using the dynamic shear rheometer test device. From the study results, the least reaction energy (30.16 kcalÁmol À1 ) barrier registered during the self-healing process of the regenerated asphalt-binder occurred at 5.8 wt% residual Soybean-oil, and was thus, deemed as the optimum oil content. The results further indicated that the residual soybean-oil had a significant influence on the spatial configuration of the molecules in the aged asphalt-binder, particularly on the saturates and aromatics components. Overall, the study findings indicated that residual Soybean-oil can potentially reduce the reaction energy barrier of aged asphaltbinders and enhance the self-healing properties including fatigue life.
