Granular-slurry rheology and asphalt compaction

Hot mixed asphalt (HMA) is a mixture of particles (coarse and fine aggregates) interstitial fluid (asphalt binder) designed to compact harden for long-lasting roads. In this study, we implement two-scale approach capture the compaction behaviour hot mixtures using both granular-slurry rheology (GSR) at smaller scale discrete element method (DEM) simulation compactor. We show that modelling effort captures HMA with different binder viscosities modified by adding graphene nano-platelets (GNP). This research has capacity shed light on how properties components can influence efficiency effectiveness.
