Simulation of Aggregate Heating in Asphalt Plants

Simulation of Aggregate Heating in Asphalt Plants. Lowering production temperature in warm mix asphalt technology may lead to inadequate drying of aggregates, resulting in low-quality asphalt production.

Simulation of Aggregate Heating in Asphalt Plants

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 the 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.
