Influence of asphalt composition upon the thermodynamics performance of a mixing plant
Résumé
Pavement material production requires a highly intensive energy processing related to the drying and the heating of granular materials within a rotary kiln. Thus, a better prediction of thermophysical parameters of bituminous concrete materials during their transformation is required to improve the processes in order to reduce their environmental impact. The present paper deals with accurate thermodynamics balance in a mix-asphalt plant.We report input and output mass flows captured within an instrumented flight rotary kiln devoted to a large range of asphalt materials.
