Abstract

Abstract In this study, the low temperature creep properties of multiphase bituminous materials (binder, mastic, Fine Aggregate Matrix—FAM, and mixture) were experimentally evaluated, and the impact of size effect on FAM and mixture specimen was also assessed. First, the mix design of mastic and FAM was performed based on the reference mixture Asphalt Concrete (AC) 22 TS. The mathematical adaptation to the boundary sieve method was applied to calculate FAM gradation and binder content. Next, a preparation method was proposed to produce Fine Aggregate Matrix (FAM) in a laboratory environment, and scale-up slab samples were also fabricated for FAM and mixture specimens to evaluate the size effect phenomenon. Finally, three-point bending (3 PB) creep tests were conducted on the multiphase bituminous specimens with different dimensions at -6 °C, -12 °C, and -18 °C with a modified Bending Beam Rheometer (BBR) device and a dynamic loading machine, depending on the sample size. Results indicate that the creep stiffness of the FAM was close to mixtures and much higher than the one observed in binder and mastic. The proposed fabrication approach provides a satisfactory method for preparing a representative FAM phase in the mixture, while the air voids can be easily adjusted during the slab compaction procedure. This study supports the idea of using FAM to discriminate asphalt mixtures for cold regions. The correlation between up-scaled FAM and mixture specimens should be further investigated, including different mixture types and corresponding FAM.

Abstract

The performance of bituminous materials is often evaluated using rheological properties measured within the linear viscoelastic region. If there is a univocal temperature dependence of all the relaxation times, data obtained in different operating conditions can be translated onto a logarithmic scale where they partially overlap and merge into a single master curve. This is the well-known time–temperature superposition principle that has been successfully applied for decades. However, the empirical nature of the method has led to many different procedures being used for the graphical construction of the master curve. In addition, the continuously increasing calculating power has led to new approaches, such as the simultaneous modelling of the represented viscoelastic function. Losing track of the basic statements of the method is the hidden drawback of this wide range of available protocols with the risk of artefacts and incongruences being introduced in the construction of the master curves. This review summarizes these basic statements together with the empirical and phenomenological approaches developed over the years. The aim of this study is to help the reader in choosing the most appropriate method to build the master curves. Although the subject of the review is of general application, the field of bitumen is focused on.

49. Multiscale modelling of bonding performance of bituminous materials

Abstract

Bonding performance of bituminous materials fundamentally determines the resistance of asphalt to fatigue cracking which is one of the major distresses in asphalt pavements. Running laboratory fatigue tests of bitumen or asphalt is costly and time consuming, resulting in empirical-based fatigue life prediction models. To reveal the debonding mechanism of fatigue damage in bitumen, a hierarchical multiscale modelling framework was developed in this thesis to understand and model the bonding performance of bitumen in order to accurately and reliably predict fatigue crack initiation and propagation in bitumen. At the nanoscale, the bonding performance of bitumen was characterised by bond energy using molecular dynamics (MD) simulations, which was validated by contact angle measurements. The MD modelling and simulations were performed to understand the effects of minerals and oxidative ageing on the bonding performance of bitumen at the molecular level. At the microscale, cohesive debonding performance of bitumen under a rotational shear fatigue load was first quantified by a DSR-C model to predict fatigue crack length. Then, based on the quantification of cohesive debonding behaviour at the nanoscale, an energy-based fatigue crack initiation criterion was developed for bitumen using a viscoelastic Griffith's theory. At the macroscale, the cohesive debonding behaviour in bitumen was modelled for fatigue crack propagation by a pseudo J-integral based Paris' law. Dynamic shear rheometer (DSR) tests were conducted to validate the developed models at different environmental and loading conditions. Results indicated that the cohesive bond energy predicted at the nanoscale can be used as a fundamental material property and scale-independent input for the cohesive debonding modelling for fatigue cracking of bitumen at the microscale. Adhesive bonding performance of bitumen with minerals is attributed to non-bond energy including van der Waals and electrostatic interactions. Bitumen oxidative ageing trends to strengthen interfacial electrostatic interaction since the introduction of oxygen atoms makes bitumen polarity stronger. The developed DSR-C model is capable of accurately predicting the fatigue crack length in bitumen. The energy-based crack initiation criterion along with the DSR fatigue tests can act as a substitute for surface energy tests. The crack propagation model based on the pseudo J-integral Paris' law is able to characterise the fatigue crack evolution in bitumen. The Paris' law coefficients A and n are temperature dependent fundamental material property, which are demonstrated to be independent of loading frequency or loading amplitude.
