主 题:asphalt-aggregate interface adhesion performance anti-stripping agents coupling agents molecular dynamics
摘 要:This study examined the mechanisms for improving the adhesion performance of the asphalt-aggregate interface with two anti-stripping agents and two coupling *** investigation of contact behavior between various asphalt-aggregate surfaces was conducted using molecular dynamics(MD)*** interaction energy and the relative concentration distribution were employed as the parameters to analyze the enhancement mechanisms of anti-stripping agents and coupling agents on the asphalt-aggregate *** indicated that the adhesion at the asphalt-aggregate interface could be strengthened by both anti-stripping agents and coupling ***-stripping agents primarily improve adhesion through the reinforcement of electrostatic attraction,while coupling agents primarily upgrade adhesion by strengthening the van der ***,the molecular dynamics modeling and calculation techniques presented in this study can be utilized to elucidate the development mechanism of the asphalt-aggregate interface through the use of anti-stripping agents and coupling agents.
