摘要
Abstract
This study investigated the adhesion mechanism between iron tailings and asphalt modified with anti-stripping agents.Three commercial anti-stripping agents(XT-1,PA-1,and ZL-16)were incorporated into 70#base asphalt to prepare modified binders.The road performance of iron tailings asphalt mixtures was evaluated,while surface free ener-gy analysis and Fourier-transform infrared spectroscopy were employed to characterize the interfacial adhesion proper-ties.Results indicated that all anti-stripping agents significantly enhanced mixture performance,with PA-1-modified as-phalt showing the most notable improvements:14.3%increase in residual stability,17.7%enhancement in freeze-thaw splitting strength ratio,and 61.4%improvement in high-temperature stability compared to the control.The sur-face free energy and chemical bonding analysis revealed the underlying mechanisms for the improved interfacial adhesion between iron tailings and modified asphalt.关键词
