Abstract

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.
