Comparative study on resilient modulus of natural and post-quake recycled aggregates in bound and unbound pavement subbase applications
Highlights Waste collected after seismic sequences offers high potential for recycling. Natural aggregate mixtures outperform recycled blends in unbound conditions. Curing time affects positively the stiffness performance of unbound samples. Resilient moduli of recycled bound samples are comparable to those of natural ones. Cement addition provides added value to recycled aggregates from mixed debris.
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.
