Abstract: Asphalt pavement consists of various sizes of aggregates coated with liquid bitumen binder and is commonly used for road construction. Producing the asphalt mixture involves heating and drying the aggregates in a rotary drum dryer before the bitumen is added. This process is very energy intensive, so thermal efficiency is a key consideration in equipment design. Using particle-based simulations engineers can investigate the effects of different drum geometries and process conditions to improve dryer efficiency. Improvements to the drying process provide economic benefit to the plant operator in the form of lower fuel costs as well as environmental benefits in reduced emissions. Visualizing the simulation data provides engineers with greater insight into the drying process and permits more effective and efficient designs. In this explanatory visualization, we leverage several platforms and scientific visualization tools to illustrate the asphalt drying process in a very high-fidelity, photo-realistic animation.
