“…Carbonyl (C=O) and sulfoxide (S=O) peak area intensities can reflect the aging and rejuvenating degree of an asphalt [29]. The functional group index can be calculated by the area of their bands by the following equations:

I_{C = O} = \frac{C a r b o n y l p e a k a r e a (c e n t e r e d a r o u n d 1700 c m^{- 1})}{P e a k a r e a (\sum^{​} 2000 a n d 600 c m^{- 1})}

I_{S = O} = \frac{S u l f o x i d e p e a k a r e a (c e n t e r e d a r o u n d 1030 c m^{- 1})}{P e a k a r e a (\sum^{​} 2000 a n d 600 c m^{- 1})}

where I C=O is the C=O peak area intensity, and I S=O is the S=O peak area intensity.…”

Waste cooking oil (WCO), in many cases, can rejuvenate aged asphalt and restore its properties. However, the influence of WCO qualities on rejuvenation behaviors of aged asphalt has not been investigated in detail. The objective of this paper was to evaluate the effects of WCO viscosity and acid value on the basic, rheological, and chemical properties of a typical rejuvenated asphalt. Penetration, ring and ball (R and B) softening point, and ductility were tested to evaluate the influence of WCO qualities on basic properties of rejuvenated asphalts. Then, the rheological properties of rejuvenated asphalt were characterized based on rotational viscometer (RV), dynamic shear rheometer (DSR), and bending beam rheometer (BBR) test results. Further, SARA (saturates, aromatics, resins, and asphaltenes) fraction analysis and Fourier transform infrared spectroscopy (FTIR) tests were performed to investigate the effects of WCO qualities on asphalt chemical composition. Finally, grey correlation coefficients were calculated and the relationships between WCO qualities and rejuvenated asphalt properties were quantitatively evaluated. The experimental results indicated that WCO qualities influence the rejuvenation behaviors of aged asphalt significantly, and the WCO with higher qualities (low acid value and viscosity, as defined in this research) tends to achieve better rejuvenation effects. Based on the results of grey correlation analyses, the acid value is, relatively, a better indicator than viscosity in predicting the rejuvenation efficiency of WCO. The rejuvenation thresholds of WCO are varied with the categories of properties of rejuvenated asphalts, and WCO with an acid value of 0.4–0.7 mg KOH/g, or a viscosity of 140–540 mm2/s, can meet all of the performance requirements for asphalt rejuvenation used in this research.

“…Asphalt binder aging involves a number of physical and chemical processes over the life of the pavement and has several causes such as oxidation, which generates an increase of the consistency of the asphalt binder, as well as the loss of volatiles. The consistency increase, especially in heavy traffic conditions, can significantly decrease the lifetime of the pavement 2. Another cause of binder aging is moisture, which usually manifests itself by cohesion loss of the mixture and adhesion loss between bitumen and aggregate surface (stripping) 3…”

The effect of solar radiation in the aging of the asphalt binder can be considered relevant in several countries due to the high level of insulation. This article deals with the comparative aging of a conventional asphalt binder and styrene‐butadiene‐styrene modified asphalt binder samples under the effect of weathering. The samples were exposed to cycles of xenon radiation, moisture, and temperature. The degradation of binders was analyzed by using the technique of Fourier transform infrared spectroscopy. The CH/CO ratio decreased 92.5% for the conventional asphalt cement and 74% for the polymer modified asphalt after 150 h of exposure in a weathering chamber. The oxidation resistance of styrene‐butadiene‐styrene modified asphalt binder was higher than the conventional asphalt cement evaluated by using the weathering test and infrared spectroscopy analysis. © 2012 Wiley Periodicals, Inc.
