Complex modulus of cement-bitumen treated materials produced with different reclaimed asphalt gradations

Abstract The increasing attention over cold recycling technologies as sustainable paving solutions requires a proper characterisation in terms of complex modulus for supporting the pavement design. Among recycled materials, cement bitumen treated materials (CBTM) benefit from presence both bituminous and cementitious binders. This research aims at characterising CBTM mixtures produced with three different gradations, modified emulsion two types cement. measurements were modelled considering usual viscous dissipation behaviour, linked to component mixtures, along time- temperature-independent component. results showed that aggregate skeleton composition fine matrix affected rheological behaviour. Furthermore, role played by aged binder contained reclaimed asphalt was highlighted parameters model.
