Abstract:Lowering production temperature in warm mix asphalt technology may lead to inadequate drying of aggregates, resulting in low-quality asphalt production. Due to difficulty in direct observation of drying and heating process and measurement of aggregate temperature inside the dryer, numerical analysis offers an alternative way to study heat transfer and aggregate temperature revolution. In this paper, coupled computational fluid dynamics (CFD) and discrete element method (DEM) is used to simulate aggregate movem… Show more
