Permanent deformation response of demolition wastes stabilised with bitumen emulsion as pavement base/subbase

•A slow-set anionic bitumen emulsion was used for road base/subbase application.•A series of multi-stage RLT tests at five distinct stress combinations were conducted.•Effect of in-service moisture on permanent deformation of aggregates was studied.•Addition of emulsion to the aggregates led to an increase in resilient strains.•The majority of the stabilized RCA and CB samples exhibited plastic creep responses.
