In this study, an innovative methodology is proposed to characterize the short-term aging of asphalt binders using the matrix analysis method. The rotational viscosity and complex shear modulus of asphalt binders were chosen as target rheological properties for the analysis of aging. A set of square matrices was developed based on test temperatures and the synthetic additive wax content. Transformational short-term aging matrices were obtained that characterize the trend of the aging process as a function of binder type, temperature sweep, and additive percentage. The results of the matrix analysis show that the trend of short-term aging depends on the binder performance grade and the rheological characteristic chosen for the analysis of aging. In addition, transformational aging matrices can provide detailed information about the range of the aging rate and the trend in aging for each binder type. Furthermore, the components of the transformational matrices clearly show the sensitivity of the binders to aging. In conclusion, the matrix analysis of aging can be used to compare the effects of short-term aging of different asphalt binders.

Several factors affect asphalt binder and mixture characteristics. This makes pavement performance assessment a mounting task. This paper evaluates the effects of short-term aging on compactibility and volumetric properties of asphalt mixtures using the Response Surface Method (RSM). Three different binders were utilized to produce mixtures (type AC-14). Aging temperature, aging duration, and duration in a climate chamber with increased humidity and ultraviolet lighting were considered as independent variables (IV), while compactibility and volumetric properties were regarded as dependent variables (DV). The findings revealed significant impacts of aging temperature and duration on compactibility, air voids, voids in mineral aggregate, and voids filled with asphalt, while duration in the climate chamber exhibited no significant influence on the DVs. The effects of IVs on DVs varied by binder type. This was achieved through an elaborate statistical analysis. The study, finally, demonstrates the RSM’s potential to predict changes in responses from mathematical equations—converging with the experimental observation—with excellent accuracy. Potentially, pavement contractors can use this method by replacing haulage duration and mixtures’ temperatures during paving in the developed models. It enables them to predict the pavement density and adjust pressure as well as the number of roller passes to achieve the desired requirements.

The fracture properties of an asphalt mixture specimen can be different due to variation in raw material characteristic, mixture design, method of the mixture production, and environmental conditions. This paper summarized the fracture properties of the semicircular specimens analyzed using different methods. Loose asphalt mixtures from two asphalt mixing plants were collected and used for the sample preparation. Each mixture was unique with respect to variation in terms of binder type, binder content, aggregate gradation, filler type, and the types of asphalt mixing plants (drum or batch plant) which were used for the production of particular mixtures. The samples were tested using semicircular bending test, and compared in terms of maximum force, deformation at maximum force, stiffness, strain at maximum force, maximum stress at failure, fracture toughness, and fracture energy. The results indicated that samples produced using stiffer binders exhibited a higher resistance to fracture while consuming less energy to reach failure compared to those prepared using softer binder. In addition, this study proposed three indicators, including the velocity of fracture initiation (υFI), velocity of crack growth (υCG), and fragility index (FI) to gain a better understanding of the fracture behavior of asphalt mixtures with respect to the mixtures’ crack resistance and its propagation. The results of υFI and υCG were highly dependent on mixtures brittleness, while FI exhibited an acceptable capability to differentiate mixtures crack potential regardless of their inherent characteristics.

This paper evaluates the fracture properties of mixtures subjected to different short-term ageing conditions obtained from semi-circular bending test. Response Surface Method (RSM) was used to develop an experimental matrix based on the central composite design. Ageing temperature, ageing duration and duration in humidity and ultraviolet chamber were selected as short-term ageing parameters, while fracture toughness or stress intensity factor (K), broken aggregate (BA) and adhesion failure (AF) were regarded as responses. Image analysis technique was employed for quantification of failures (including adhesion and cohesion failures) on the fractured surface of mixtures. The susceptibility of mixtures’ fracture properties to temperatures was also determined in terms of KTS. The responses were analysed using RSM. The results showed that ageing temperature and ageing duration were the dominating ageing factors affect responses. Ageing increment resulted in higher K and BA while exhibited contradictory effects on AF. Test temperature increment reduced the fracture toughness. The KTS was increased at higher temperatures. Lastly, RSM and image analysis technique exhibited great reliability and capability to study the behaviour of the responses exposed to various ageing conditions.

Over the years, asphalt pavement materials age, causing binder embrittlement which adversely affects pavement service life. This paper employed Response Surface Method (RSM) to determine the optimal mix from the standpoint of short term aging based on mixtures’ fracture properties obtained from the Semi-Circular Bending (SCB) test. In order to short term age the mixtures, an experimental matrix was designed based on the central composite design. Aging temperature, aging duration and duration in humidity and ultraviolet chamber were considered as short term aging factors or independent variables (IV). The maximum force, deformation at maximum force, strain at maximum force, stiffness, fracture energy, maximum stress at failure, fracture toughness, velocity of fracture initiation, fragility index, and velocity of crack growth as the SCB test outcomes or dependent variables (DV) were analyzed using RSM. The results showed that the effects of IVs on the DVs change with changes in either binder type or binder content. For instance, the maximum fracture energy of mixtures produced with binder A60 were 3197.8 and 2599.1 J/m2 at 10 and 30 °C, respectively, while the corresponding values of mixtures produced with binder B80 were 5112 and 1725.9 J/m2 at 10 and 30 °C, respectively. Aging up to some level exhibited beneficial impacts on mixtures’ fracture properties, which was considered as the optimal mix. The short-term aging level of optimal mix for the mixtures with stiffer binder was lower, compared to those produced with softer binders. For example, aging temperature to achieve optimal mix for mixtures prepared using binder A60 was 124 °C at 20 °C, while the corresponding value for mixtures produced with binder A80 was 142 °C at the same temperature. Crossing the optimal mix, made the mixtures become brittle, which was not desirable especially at lower temperatures.

Asphalt binders and mixtures are more susceptible to permanent deformation at high temperature. The Dynamic Shear Rheometer (DSR) test results have been extensively used to evaluate the effects of wax and foamed warm additives on asphalt binder properties at elevated temperature. Wax based additives improve the rheological properties of the binders at high temperatures, while foamed based additives exhibit no significant effects on binder rheology. However, the literature reports contradictory effects of surfactant-wax warm additive named Rediset, on binders and mixtures propertiesat high temperatures. Some studies reported positive effects, while others found otherwise. This paper evaluates the effects of binder type, additive content and loading type on high temperature properties of warm asphalt binders incorporating Rediset on temperature, strain, frequency and stress sweep tests as well as flow, creep, multiple stress creep and recovery and zero shear viscosity test results. The results showed that the effects of Rediset depended on binder type, additive content and loading type. It implies that the chemical composition of different dosage of this warm additive with various binder types, directly affect the performance of binders subjected to various loading types at high temperatures. Hence, simply relying on one type of shear loading in the DSR test for evaluating the high temperature properties of binders incorporating a surfactant-wax additive, can lead to erroneous conclusions.

Many factors affecting pavement performance include variations in binder composition and environmental conditions during asphalt mixture production. Hence, predicting pavement performance is a difficult task. This paper aims to investigate the effects of short term aging on binder viscosity at high temperature. In order to predict the effects of short term aging on the asphalt binder viscosity at high temperatures, a Response Surface Method was performed on the Rotational Viscometer test results. An experimental matrix was planned based on the central composite design for aging duration and test temperature. The test results showed that aging increased the binder viscosity, while increasing test temperature decreased the corresponding value. However, aging effects differ and depend on binder types, test temperatures and aging conditions. It was also found that the Response Surface Method is a fast, effective and reliable method to predict the effects of aging on binder viscosity behaviour at high temperatures.

Many factors affect pavement service life. Aging as one of these factors occurs due to binder volatilization and oxidation. Aging increases binder viscosity and subsequently results in stiffer mixtures. Transportation of asphalt mixture from plant to field may cause variations in the levels of aging. This study attempts to determine the effects of aging on mixture permanent deformation or rutting during transportation from plant to field and to simulate the aging conditions in the laboratory. The rutting parameters evaluated include creep stiffness, cumulative strain, creep modulus and creep rates of mixtures collected from plant, field and samples artificially produced in the laboratory. The results showed that temperature increment significantly changed mixtures rutting properties, while aging during mixture transportation from plant to field has no effect on rutting. It was also found that artificially aging the mixtures by varying aging duration that conducted for this study, cannot exactly simulate the plant and field aging conditions.

Predicting the effects of short term aging on asphalt binders’ rheological properties can be a complicated task. This is due to the exposure of different binders to different conditions. Hence, the utilization of a Respond Surface Method (RSM) is a practical way to predict these effects. An experimental matrix was planned to predict asphalt binders behavior at intermediate temperatures based on the central composite design for aging duration and test temperature. The test results showed that prolonging aging increased the binder complex modulus, but decreased the phase angle, while increasing the test temperature decreased the complex modulus but increased the phase angle. However, the trends in aging differ and depend on the binder type, test temperature and aging conditions. It was also found that the RSM method is a fast, effective and reliable tool to predict the effects of aging on binders’ rheological behavior.
