Abstract

Abstract The present paper deals with the potential employment of recycled debris in the field of road pavement engineering. In particular, the resilient behaviour of a recycled aggregate mixture produced from mixed post-quake debris is compared with that of a natural blend in both bound and unbound applications as road subbase layers. An experimental campaign based on cyclic load triaxial tests has been carried out to determine the resilient modulus of materials, which has been investigated after different periods and conditions of curing. Comparative analysis demonstrates that cement addition provides added value to recycled aggregates from mixed debris, whose resilient properties result comparable to those of virgin aggregates when employed in bound applications.
