Review of Interface Fusion State and Recycling Behavior of Asphalt Based on Molecular Dynamics
摘要
Abstract
Asphalt recycling technology can effectively use reclaimed asphalt pavement(RAP),alleviate the shortage of stone resources,reduce the damage to the ecological environment,and promote sustainable road development.However,the RAP content in recycled asphalt mixture should not be too large due to the interface fusion state of new and old asphalt and the poor effect of asphalt recycling behavior.Based on molecular dynamics theory,the fusion mechanism of new and old asphalt is explored from the perspective of asphalt material,fusion state of new and old asphalt and asphalt recycling behavior,the tradi-tional evaluation methods of asphalt recycling behavior are summarized and analyzed from the macro,meso and micro levels.Results indicate that with the increase of RAP content,the high-temperature performance and water stability performance of the recycled asphalt mixture will be improved,and the effect of asphalt interface fusion can be analyzed by Fourier trans-form infrared spectrometer(FTIR)and atomic force microscope(AFM).But the relationship between the molecular dynam-ics simulation results and macro and micro properties of asphalt is not clear and requires further investigation.关键词
