Particle Breakage and Fines Generation of Recycled Concrete Aggregates Subjected to Compaction
In this study, the particle breakage and fines generation of due to compaction were investigated for recycled concrete aggregates (RCA). RCA samples containing two common aggregate types, i.e., sedimentary versus igneous, were selected and compacted with a modified Proctor compaction procedure. Sieve analyses pre- and post-compaction showed that both types of RCA were more susceptible to particle breakage when compared to virgin dolomite aggregates. In particular, the sedimentary RCA sample containing dolomite aggregates exhibited significant levels of breakage and fines generation. Degradation of such RCA materials due to compaction may lead to reduced drainage performance and heightened clogging potential, and therefore should be evaluated before they are used as fill materials.
