The term "sand equivalent" expresses the concept that most fine aggregates are mixtures of desirable coarse particles (e.g., sand) and generally undesirable clay or plastic fines and dust (ASTM, 2003 [1] ).These materials can coat aggregate particles and prevent proper asphalt binder -aggregate bonding.
