The main objective of this experimental research is to prove the hypothesis of the use of recycled materials (C&D) in building road subbases by means of a comparative study which investigates the resilient behaviour of unbound aggregate blends. The results given by the investigation clearly prove that the blend made of recycled materials has shown a resilient behaviour very similar to that of a typically frictional material, such as a virgin granular material coming from quarry aggregates. A low susceptibility to water and a marked influence of confinement pressure on the blend stiffness are the properties which prove this similar behaviour.

Abstract
The main objective of this experimental research is to prove the hypothesis of the use of recycled materials (C&D) in building road subbases by means of a comparative study which investigates the resilient behaviour of unbound aggregate blends. The results given by the investigation clearly prove that the blend made of recycled materials has shown a resilient behaviour very similar to that of a typically frictional material, such as a virgin granular material coming from quarry aggregates. A low susceptibility to water and a marked influence of confinement pressure on the blend stiffness are the properties which prove this similar behaviour.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
