“…In terms of accuracy, the fitting curve established by physical properties is easily affected by human factors. [ 7 ] The correlation coefficients (R 2 ) of linear and quadratic fittings between viscosity and SBS content are less than those of infrared spectroscopy.…”

The identification of styrene-butadiene-styrene (SBS) content is crucial in engineering applications since the key to assessing the performance of agedmodified asphalt is the SBS content. Six types of modified asphalts with various SBS contents were prepared, and physical, rheological, and Fourier-transform infrared spectroscopy (FTIR) tests were conducted. The fitting relationship between aged-modified asphalt indexes and SBS content was established, and the three methods' accuracy, simplicity, and efficiency were compared and analyzed. The results showed that the fitting relationship between SBS content and viscosity could exceed 0.83 after aging. However, the linear and quadratic fittings deviated from the measured values, and the softening point had no apparent law with the SBS content. The rheological index method significantly correlated with SBS content and is highly automated. However, FTIR was established based on the direct detection of SBS characteristic peaks compared with the physical and rheological indexes methods. It could directly reflect the SBS content and was not easily disturbed by SBS substitutes. In addition, after long-term aging, the linear relationship between SBS characteristic peak index, A 966 /A 811 , and SBS content could exceed 0.97. The FTIR test exhibited high accuracy and fast detection speed and is the best detection method for SBS content.

“…Penetration and softening point reflecting the consistency and the constant temperature viscosity were used to evaluate the high-temperature deformation resistance of the asphalt mortar. Ductility was used to evaluate the low-temperature plastic deformation ability of the asphalt mortar [49,50]. The corresponding test results of these physical properties are presented in Figure 1.…”

To explore the applicability of steel slag porous asphalt mixture, the interaction capability and microscopic interfacial mechanism between asphalt-binder and steel slag aggregate-filler were investigated in this laboratory study. These objectives were accomplished by comparing and analyzing the differences between steel slag and basalt aggregates in interacting with the asphalt-binder. The study methodology involved preparing basalt and steel slag asphalt mortar to evaluate the penetration, ductility, softening point, toughness, and tenacity. Thereafter, the interaction capability between the asphalt-binder and aggregates was characterized using the interaction parameters of the asphalt mortar obtained from dynamic shear rheometer (DSR) testing. For studying the functional groups and chemical bonding of the asphalt mortar, the Fourier Transform infrared (FTIR) spectrometer was used, whilst the interfacial bonding between the asphalt-binder and aggregates was analyzed using the scanning electron microscope (SEM). The corresponding test results indicated that the physical and rheological properties of the two asphalt mortars were similar. However, whilst the FTIR analysis indicated domination through chemical reactions, the interaction capability and interfacial bonding between the asphalt-binder and steel slag aggregates exhibited superiority over that between the asphalt-binder and basalt aggregates, with pronounced adsorption peaks appearing in the steel slag asphalt mortar spectrum. On the other hand, the SEM test revealed that, compared with the basalt, the micro-interfacial phases between the steel slag and asphalt-binder were more continuous and uniform, which could potentially enhance the interfacial bond strength between the asphalt-binder and aggregates (filler).

“…In some cases, the required properties can be changed by changing the properties of the mineral filler. [18][19][20][21] Adhesion improvers are surfactants that lower the surface tension in the bitumen-aggregate phase and thus improve wetting. A number of scientific articles present the results of testing the use of additives and indicate their positive effect on the adhesion of bitumen to aggregate to acidic and neutral aggregates (granite, quartz).…”

Abstract. Premature destruction of asphalt concrete can be caused by the aging of bitumen, which is associated with a change in the physical and chemical properties of bitumen. The article shows that in most cases, the improvement of the characteristics of asphalt concrete is achieved through the introduction of additives that affect the basic properties of the bituminous binder, such as penetration, softening temperature, viscosity. The influence of the chemical composition of the mineral filler on the rate of bitumen aging has been experimentally proved. The obtained research data show that the increase in the rate of aging of bitumen is influenced by the compounds of silicon and aluminum. On the other hand, metals such as iron and titanium contribute to the preservation of the initial plasticity of bitumen, and the accumulation of asphaltenes in the structure of the bitumen-mineral mixture slows down.
