This article investigates the use of coupled computational fluid dynamics (CFD) and discrete element methods (DEMs) to simulate heat transfer in an aggregate drum dryer used production hot mix asphalt. To be properly coated by asphalt binder, must completely dried, a process accomplished counter flow heated direct fire burner. Attached flighting is positioned inside facilitate transfer. Because observation impossible, commercial codes from FLUENT DEM solutions were burner flame aggregate. A...
The use of reclaimed asphalt pavement (RAP) in mix contributes to sustainable construction. However, a high percentage RAP causes concern about compromising the performance pavement, especially cracking. binder transfer and blending between virgin aggregate during production an plant is critical procedure that affects mix. heating by superheated can affect degree which are blended thus mixes containing RAP. Several parameters, such as percentage, mixing time, moisture content, binder. To...
Heating aggregates and recycled materials is an energy intensive part of the process producing asphalt pavement. Sustainability can be improved by increasing portion while decreasing required to produce mixture. A common method incorporate mix heated aggregate with cold materials. Interstitial gas conduction dominant mode heat transfer in this due low thermal conductivity these In study, a particle-based model that includes contribution interstitial gases was validated novel experimental...
