This paper presents the results of an experimental investigation which focused on self-compacting cement-bound mixtures to be employed for paving applications, especially for pavement foundations in road tunnels. Recipes of the investigated mixtures, which contain reclaimed asphalt pavement material and mineral sludge, were defined by optimizing the packing of the aggregate skeleton and by checking the flowability characteristics of cement pastes and composite mixtures. Long-term stiffness and strength properties were evaluated by means of triaxial and quick shear tests. Based on the obtained results and on their interpretation, a mix design procedure was proposed. General conclusions were drawn with respect to the behaviour of self-compacting cement-bound mixtures and to the possible developments of future research.
