Abstract Recycled concrete aggregates are produced by recycling demolished concrete elements. They contain relatively weak cement mortar attached on to aggregate particles which tends to break and separate from aggregate particles during mechanical mixing, vibration or compaction of cement or asphalt concrete. This was studied for an asphalt concrete containing recycling concrete aggregates and it was found that the change in particle size distribution during mixing and compaction was significant compared to that of a fresh aggregate sample. This had a considerable effect on the volumetric properies determined for an asphalt concrete sample.
