“…They found that bitumen materials stabilized with emulsion and recycled aggregates from construction and demolition (C&D) are more flexible, showing improved resistance to permanent deformation and similar stress failures in comparison to mixtures with natural aggregates. That said, a higher water and bitumen content is needed [17].…”

“…Finally, for the resilient modulus and permanent deformation tests ( Figure 2) the BSM samples were prepared with a diameter of 100 mm and a height of 200 mm with the two types of aggregates as published by Gómez-Meijide and Pérez [14]. All the samples with NA were manufactured with 3%…”

This study presents the numerical modelling of a load-volume road pavement section with bitumen emulsion-stabilised base courses. The base courses used natural and construction and demolition aggregates. A 3D finite difference model was used to determine the peak responses of the pavement sections when subjected to loads. Three nonlinear models were adopted in the two base courses. The response predictions of the three models were similar. Both the resilient and permanent behaviours of these materials were modelled. An analysis was conducted on the rutting resistance of the base course materials. Both base courses were suitable for use in low-volume roads. The base course made with construction and demolition aggregates was more resistant to rutting.

“…One of the most cost-effective and environmental-friendly modes of employment of RA is represented by cold-recycling, in which RA is combined with asphalt emulsion or foamed bitumen to create a stable and durable paving mixture [ 15 ]. Although cold-recycling techniques have traditionally been used in low-volume roads due to the poorer mechanical properties of corresponding mixtures [ 8 , 16 , 17 , 18 , 19 , 20 ], promising research has been reported in which cold-recycled asphalt mixtures exhibited performance in the field comparable to that of standard bituminous layers containing exclusively virgin materials [ 21 , 22 , 23 , 24 , 25 , 26 , 27 , 28 , 29 , 30 , 31 , 32 , 33 , 34 ].…”

This paper presents the results of an experimental investigation which was carried out with the purpose of assessing the performance-related properties of an emulsion-based cold-recycled mixture to be employed as a sustainable solution for the surface finishing of unpaved rural roads. This mixture contained significant quantities of recycled components (reclaimed asphalt and mineral sludge), and its composition was fine-tuned by following an innovative mix design procedure. Properties of these mixtures were studied by means of laboratory tests which considered key parameters, such as flowability, indirect tensile stiffness modulus, indirect tensile strength, moisture susceptibility and resistance to permanent deformation. It was found that, by means of the proposed mix design procedure, optimal dosages of the recycled components can be identified, thereby ensuring the achievement of the desired properties in terms of high workability and adequate stiffness and strength.
