Recycling　of　reclaimed　asphalt　pavement　(RAP)　faces　significant　challenges　due　to　interfacial　interaction　problems　within　reclaimed　asphalt　mixtures　(RAM).　This　review　focuses　on　two　critical　interfaces　within　RAM:　the　interface　between　fresh　and　aged　asphalt,　and　the　interface　between　aged　asphalt　and　aggregate.　These　interfaces　exert　a　profound　influence　on　the　performance　of　RAM,　impacting　key　pavement　attributes　such　as　rutting　resistance,　fatigue　life,　and　moisture　damage　resistance.　Consequently,　a　comprehensive　understanding　and　enhancement　of　these　interfacial　interactions　are　essential　for　optimizing　RAP　utilization　and　elevating　the　overall　performance　of　RAM.　The　review　commences　with　systematic　analysis　of　two　pivotal　interface　properties　within　RAM.　It　delves　into　the　definition　of　these　interfaces,　elucidates　the　factors　influencing　their　performance,　and　meticulously　examines　the　methodologies　employed　to　evaluate　their　characteristics.　Subsequently,　the　review　investigates　the　impact　of　rejuvenating　agents,　including　petroleum-based　oils,　bio-based　oils,　and　chemical　modifiers,　on　enhancing　interfacial　properties.　Additionally,　the　role　of　surface　treatment　techniques,　such　as　chemical　treatments　and　mechanical　grinding,　in　augmenting　interfacial　adhesion　between　asphalt　and　aggregates　is　discussed.　While　progress　has　been　made　in　interfacial　study,　several　challenges　persist.　Consequently,　the　review　concludes　by　providing　some　recommendations　for　future　research　endeavors.　These　recommendations　aim　to　overcome　the　existing　challenges　and　advance　the　field　of　RAM　interfacial　property　enhancement.
