Resilient modulus of recycled aggregates obtained by means of dynamic tests in a triaxial apparatus

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.
