AB  - This study aims to assess the feasibility of using copper slag (CS) in asphalt mixtures in both the surface and base
layers of road pavements. For this purpose, two sets of asphalt mixtures with different CS content (15 and 30%)
and fraction sizes (0/8 and 0/16 mm) were prepared. The optimal binder content of each mixture was determined
using the Marshall mix design method. Their laboratory performances were investigated and compared
with the properties of reference asphalt mixtures, i.e. mixtures consisting exclusively of virgin materials. Test
results showed that adding CS to the mixture for the surface layer improved stiffness and rutting resistance and
had almost no negative impacts on the remaining properties apart from cracking resistance. Further, the addition
of CS to the base-layer mixture improved cracking resistance, but negatively affected stiffness, rutting and fatigue
resistance. In both cases, adding CS did not influence the strength, water sensitivity or freeze–thaw resistance.
From a leaching perspective, the results showed that leachates gathered from the asphalt mixtures designed for
the surface layer did not contain heavy metals. Overall, it can be concluded that CS has a potential to be used as
an appropriate aggregate substitute for virgin aggregates in asphalt mixtures for both surface and base layers.

AB  - Recently, the reduction of the environmental burdens related to highway infrastructures has been in the spotlight. Within this context, the use of recycled materials in bituminous mixtures for road pavement construction and maintenance has the potential to mitigate the excessive use of non-renewable resources. Nevertheless, the material consumption is only one of the aspects that affects the sustainability of an infrastructure. Other relevant aspects related to environmental issues should be considered. The objective of this work is to evaluate the potential environmental impacts of asphalt mixtures containing crumb rubber (CR) (vulcanised or devulcanised) and reclaimed asphalt pavement (RAP) assuming different Degree of binder Activation (DoA) of the aged binder by means of a life cycle assessment (LCA). The results show that the small amount of CR used for bituminous mixtures application does not justify all the additional consumption of resources and emissions associated with its treatment. These results are explained by the higher environmental impacts stemming from the treatment of the rubber and the higher amount of bitumen employed in the mixture. In turn, for mixtures containing RAP the analysis revealed an improvement in the score of all the environmental indicators considered.
