This paper deals with an experimental study for the characterization of Construction and Demolition (C&D) waste to be used in road construction. The research was carried out both in laboratory, to determine the most suitable mixtures, and in situ, to evaluate their bearing capacity and durability. Relying on the results, different bound and unbound mixtures were then manufactured. To evaluate the on-site performance of these materials, a full-scale experimental field was built in an area of suitable characteristics. The field was composed of a first layer of unbound C&D materials and a second layer of cement stabilized C&D materials. Finally, bearing capacity surveys were carried out using deflectometric devices, and monitoring the density and the moisture of the material. A first analysis of the results shows that both the bound and the unbound mixtures meet the specification requirements in terms of mechanical performance in laboratory and on-site bearing capacity.

Abstract
This paper deals with an experimental study for the characterization of Construction and Demolition (C&D) waste to be used in road construction. The research was carried out both in laboratory, to determine the most suitable mixtures, and in situ, to evaluate their bearing capacity and durability. Relying on the results, different bound and unbound mixtures were then manufactured. To evaluate the on-site performance of these materials, a full-scale experimental field was built in an area of suitable characteristics. The field was composed of a first layer of unbound C&D materials and a second layer of cement stabilized C&D materials. Finally, bearing capacity surveys were carried out using deflectometric devices, and monitoring the density and the moisture of the material. A first analysis of the results shows that both the bound and the unbound mixtures meet the specification requirements in terms of mechanical performance in laboratory and on-site bearing capacity.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
