“…Atomic force microscopy (AFM) was employed to investigate the interfacial interaction and adhesion strength between asphalt binders and mineral surfaces [4,5]. Dynamic Mechanics Analyzer (DMA) testing [6] and Dynamic shear rheometer (DSR) testing [7] were carried out to characterize the adhesion bond strength and adhesion fatigue performance of asphalt concrete composites under shear loading. Pull-off tests were performed by pneumatic adhesion tensile testing instrument (PATTI) and universal testing machine (UTM) to study the interface tension failure between asphalt and aggregate with and without moisture [8,9].…”

“…The first stage corresponds to the linear elastic behavior of asphaltaggregate interface. In this case, since the interfacial bonding is the weakest link, which is caused by different theories [16,25], the second stage corresponds to the interfacial failure between asphalt and aggregate. After a transition phase of the cohesiveadhesive hybrid failure, the third stage regarded as reascending part is due to the separation of molecules within the asphalt film and the shear stress increases again until reaching the second peak value.…”

“…Liu et al [15] showed that limestone aggregates could perform better than granite aggregates for moisture resistance and also suggested that the physico-chemical properties of aggregates may play a fundamental and more significant role in the generation of moisture damage than bitumen properties. Mo et al [16] concluded that the adhesive zone between stone and mortar tended to be the weakest link by comparing the experimental results in the interface region.…”

“…Research efforts have been made to investigate the influence of interfacial bonding conditions on the mechanical properties of asphalt mixture. Interfacial bonding in the adhesive zone due to stone surface morphology and asphalt film thickness often have a significant influence on the failure mechanism [16][17][18]. Therefore, more comprehensive and accurate knowledge of the interface is necessary to better understand the asphalt-aggregate systems, and some significant work, such as shearing fracture mechanism, needs to be done.…”

In order to investigate the mechanical behavior of asphalt-aggregate systems subjected to direct shear loading and reveal the shear failure mechanism, four groups of direct shear tests were conducted on composite specimens under different experimental conditions with a self-manufactured direct shear test apparatus at 25°C. Comparative studies were conducted to evaluate the effects of stone surface treatment, asphalt film thickness and loading rate on the shear mechanical behavior of asphaltaggregate specimens. Results showed that two kinds of the complete stress-displacement curves, including the general single-peak curve and the first-known double-peak curve, were clearly observed for each condition. In addition, the internal failure mechanisms were analyzed based on qualitative and quantitative methods. It can be concluded that the potential failure modes of the direct shear test include adhesive failure at the asphalt-aggregate interface and cohesive failure within the asphalt film. The research results enhance understanding of the shear mechanical behavior and failure mechanism of asphalt mixture, and also provide a reference for the interfacial failure.

“…The corresponding theory is being employed as a cutting-edge technique in the study for composite materials [2], and current research related to adhesion characteristics of asphalt-aggregate bonding has been taken account into hot mix asphalt (HMA). The corresponding methodologies can be divided into three major categorizations that are dependent on physical scales: micro-scale [3], meso-scale [4], and macro-scale [5]. Numerical simulations and analytical approaches are commonly applied at these scales, such as molecular dynamics (MD) [6], finite element method (FEM) [7], and discrete element method (DEM) [8].…”

Examination of Poly (Styrene-Butadiene-Styrene)-Modified Asphalt Performance in Bonding Modified Aggregates Using Parallel Plates Method

et al. 2019

Although asphalt-aggregate bonding provides contacting strength for hot mix asphalt (HMA), it is still ignorant in dynamic shear test, due to the only use of metal parallel plate. Modified parallel plates cored from different types of aggregate were provided to simulate aggregate-asphalt-aggregate (AAA) sandwich in HMA, aiming at the comprehensive interpretation on bonding’s influence. This study began with an experimental design, aggregate plates, and joint clamps were processed to be installed into the rheometer. Aggregate type and loading conditions were set as essential variables. Subsequently, microscopic tests were utilized to obtain chemical components of aggregate, micro morphology of interface, and roughness of plates. The shearing tests for poly (styrene-butadiene-styrene)-modified asphalt were conducted in bonding with aggregate plates. Meanwhile, contrasting groups adopting metal plates followed the same experimental procedures. The results indicate that the influence of aggregate type on binder’s rheological characteristics is dependent on the experimental variables, and microscopic characteristics and component differences should be taken into consideration when selecting aggregates in designing asphalt mixtures.
