“…The population numbers of epoxy modified asphalt were calculated by first principle and molecular dynamic [11]. The solubility of layered double hydroxides modified asphalt were studied by molecular dynamic simulations [12][13]. The three and four components asphalt model were recently established using molecular dynamic simulations and the components schematic structure were drew by Chew-draw software [14].…”

The objective aims to study the bonding, deformation and failure behavior of carbon nanotubes-asphalt interface using molecular simulations. The electronic structure and electrical properties of carbon nanotubes modified asphalt (CNMA) were investigated by first-principle molecular dynamic including density of state and band structure. Tensile simulation through uniform stress were measured and the stress responses were obtained to analyze the interface mechanical behavior. It indicated that carbon nanotubes (CNTs) could improve remarkably the electrical and mechanical property of asphalt. Molecular dynamic simulation results showed that failure modes of the interface between CNTs and asphalt turned out to be mainly adhesive failure rather than cohesive failure. The interface failure strength and maximum deformation were affected by carbon nanotubes and temperature that was consistent with the viscoelastic behavior of asphalt binder.

“…Fine aggregate mixture(FAM) is a composite which consists of three different types of materials: bitumen, aggregate and mortar. Bitumen contains a wide variety of organic molecules, and widely used in pavement, waterproofing, roadway maintenance and micro-surfacing [1,2]. Aggregates are generally of mineral origin, varying from hard basaltic rocks to softer eroded river sand [3].…”

Three-dimensional depth of field microscope (3-D FM), scanning electronic microscope (SEM) and molecular dynamic simulation (MD) were used to evaluate the surface morphology, behaviors and failure mechanisms of mortar and fine aggregate mixture (FAM). The effects of ultraviolet (UV) light and moisture for FAM, the interfacial behaviors of bitumen-aggregate were investigated. Results showed that in the pure mortar, the UV-ageing could increase the adhesion between the bitumen and fine aggregates, and the cohesion failure was dominant after UV-ageing. Due to the lower air voids in the pure mortar, the moisture did not cause the adhesion failure. The molecular dynamic simulation implied that UV ageing and moisture-treatment could reduce the interfacial energy, and the aromatic and asphaltene played a great role in the adhesion between bitumen and aggregate.
