“…Herrington (2012) measured the normalized carbonyl area in a range from 1640 to 1810 cm -1 and divided it by the area under 1600 cm -1 peak (using 1810 cm -1 as a baseline), to solve the variations in sample concentration [8]. Liu et al (2015) introduced a carbonyl index as the ratio of carbonyl area under 1700 cm -1 peak to that of methylene group under 1375 cm -1 peak to eliminate the effect of bitumen sample thickness on the carbonyl area [9]. Another adopted method was to divide the carbonyl area under the 1700 cm -1 peak by the summation of all absorbance areas for the bitumen [10] or a portion of it [11].…”

This paper investigates the effect of different anti-ageing compounds (AACs) on the oxidation kinetics of bitumen using Fourier Transformation Infrared (FTIR) spectroscopy. Twenty different AACs were examined, including new and existing AACs for bitumen and polymer products. The AACs were mixed with bitumen to fabricate thin film samples of AAC-modified bitumen which were subjected to laboratory oven ageing at 100 ºC with different ageing periods up to 504 hours. A Normalized Carbonyl Index (NCI) was proposed based on a selected reference peak (1377 cm-1) to eliminate the impact of the inherent carbonyl content from the bitumen or AACs and manifest the carbonyl growth rate for evaluating the AACs' anti-ageing performance. It was found the activation energy of fast-term oxidation can be utilized to quantitatively screen the anti-ageing compounds and evaluate their anti-ageing effectiveness in terms of decreasing the formation of carbonyl groups in bitumen. AACs that exhibited high anti-ageing performance were those contained furfural, Irganox acid with sodium montmorillonite, furfural with DLTDP, and high concentrations (e.g., 15%) of Irganox acid. The proposed protocol should be followed by further laboratory rheological and mechanical tests on the AAC-modified bitumen with different binder sources.

“…According to AFM analysis, nano-ZnO decreases the contrast between the bee-like structures and matrix in bitumen B1. Meanwhile, nano-ZnO has a good absorbance of the UV light, the highest absorbance value can reach up to 1.4 (Liu et al, 2015). As a result, the association of the dispersed domains can be prevented effectively during UV aging, which contributes to the good UV aging resistance of nano-ZnO modified bitumen B1.…”

“…However, less attention of the researchers has been paid to the UV aging resistance in comparison with thermal oxidative aging. According to our previous research, compared with nano-calcium carbonate, nano-silica, and nano-titanium, nano-zinc oxide (nano-ZnO) shows the best improvement in UV aging resistance of bitumen (Liu et al, 2015;Zhang et al, 2015). As previously mentioned, bitumen is a complex system made of different organic constituents, usually named saturates, aromatics, resins and asphaltenes.…”

Effect of nano-zinc oxide (nano-ZnO) on the morphology and ultraviolet (UV) aging properties of two bitumens was investigated by atomic force microscopy, physical properties and Fourier transform infrared spectroscopy before and after UV aging. The results show that the mechanism of nano-ZnO depends on the base bitumen. In one case, nano-ZnO contributes to the homogeneous dispersion of bee-like structures. In the other case, it leads to the separation of asphaltenes from the matrix. Compared with B2, nano-ZnO exhibits a better improvement in UV aging resistance of B1 by showing the lower increased viscosity values, rheological aging index, and carbonyl indexes.

“…e short-term aging performance was also significantly improved, and good results have been achieved in actual engineering. Liu et al [9] used different surface modifiers to modify the surface of nano-ZnO. It was found that nano-ZnO-modified asphalt showed the smallest VAI value and carbonyl index after UV aging, indicating that it had good resistance to ultraviolet aging.…”

In order to address the influence of aging on the performance degradation of SBS-modified asphalt, a composite modification of SBS-modified asphalt by nano-zinc oxide (nano-ZnO) and Trinidad Lake asphalt (TLA) was proposed. Several tests were conducted after adding nano-ZnO and TLA to SBS-modified asphalt, including a rotary film oven test (RTFOT), ultraviolet aging (UV), and the pressure aging vessel test (PAV). The conventional physical index, rheological index, and four-component content of SBS-modified asphalt before and after three aging modes were tested, and the characteristic functional groups in SBS-modified asphalt were tracked and analyzed by Fourier transform infrared spectroscopy (FTIR). The results show that the effects of aging on the rheological properties of SBS-modified asphalt are clearly reduced by adding different proportions of nano-ZnO and TLA in the process of thermal oxygen aging and the ultraviolet aging test, and the antiaging ability of SBS-modified asphalt is clearly improved. To improve the conventional performance and rheological properties of SBS-modified asphalt, an incorporation ratio of 3% nano-ZnO + 25% TLA was proposed. At the same time, the increased rate of heavy components and the change index of the colloidal instability index in the SBS-modified asphalt under the blending ratio were significantly lower than the blank SBS-modified asphalt samples in the same aging mode. FTIR spectra also showed that SBS-modified asphalt performance deterioration were mainly caused by long-term aging and ultraviolet aging. The addition of nano-ZnO and TLA effectively reduced the increase of carbonyl groups and the breakage of the C=C double bond in butadiene and synergistically improved the comprehensive aging resistance of SBS-modified asphalt. Therefore, the use of this modification is an effective method to solve the aging problem of SBS-modified asphalt.
