Despite　the　fact　that　ability　of　bituminous　materials　to　heal　damage　has　been　largely　studied　and　that　a　wide　literature　is　available　on　this　topic,　there　is　still　no　consensus　in　the　research　community　on　actual　factors　governing　healing　process　and　methods　to　be　used　to　quantitatively　asses　healing　performance　of　bituminous　materials.　In　such　a　context,　one　of　the　main　objectives　of　the　RILEM　Technical　Committee　278-CHA　is　to　evaluate　the　different　test　methods　proposed　by　various　research　teams　to　characterize　healing　in　bituminous　materials　and　come　up　with　clear　and　concise　recommendations　regarding　the　evaluation　of　healing　behavior　of　bituminous　materials　in　the　laboratory.　To　this　regard,　an　inter-laboratory　experimental　program　has　been　recently　started　with　the　specific　purpose　of　testing　a　common　set　of　selected　bituminous　binders　by　using　three　different　protocols.　This　paper　describes　the　protocols　adopted　in　the　experimental　program　and　reports　some　preliminary　results　obtained　to　date.　©　2022,　The　Author(s),　under　exclusive　license　to　Springer　Nature　Switzerland　AG.
