An Example for Determining the Physical Parameters Used in DEM Modelling for the Interaction Process between Aggregates and Working Equipment

Modern economies are based on an efficient communications and transport infrastructure. In this context, road networks make essential contribution to the movement of large quantities raw materials, finished products as well human for productive or recreational purposes. order maintain optimal functioning infrastructure, it is necessary ensure high quality lanes. Road construction maintenance work play important role in supporting ideas mentioned above. The used equipment production asphalt pavements (asphalt concrete) their subject numerous studies, proving interest field. authors paper: An Example Determining Physical Parameters Used DEM (Discrete Element Method) Modelling Interaction Process between Aggregates Working Equipment, present example determining physical parameters that specific numerical modelling operation which interacts with structures (drum dryer, mixer concrete milling machine pavement). model real phenomena granular materials involved (cereals, mineral aggregates, other powdery substances) very use not only appropriate software but also primary data accurately characterize phenomena. sizes interaction particles space they move important. study covers any type material origin, particular aggregates manufacture concrete, cement asphalt.
