Permanent and resilient deformation behaviour of recycled concrete aggregates from different sources, in pavement base and subbase
Source abstract
Abstract
This paper presents an investigation on the permanent and resilient deformation behaviour as well as the shear and physical properties of different RCA, sourced from demolished buildings (RCAB1 and RCAB2) and concrete pavement (RCAP). Monotonic triaxial tests and repeated load triaxial tests (RLTT) were performed to determine respectively their failure resistance and the cyclic behaviour, modelled with the Boyce model and the DBGSP model. In addition, the physical properties and water absorption kinetics of aggregates were studied and compared with the existing standard. The results indicated that all RCA have admissible physical properties and can be used in pavement base and subbase layer. However, the RLTT revealed that the use of concrete wastes with low strength and containing high amount of rounded particles (RCAP in this study) can lead to poor performance of pavement, which should be limited in the pavement construction.
