Abstract
A method for packing bitumen in a continuous process is disclosed. To pack the bitumen, a tray having one or more bitumen-receiving cavities is prepared. The cavity of the tray is coated with polymer film and bituminous film consecutively. Following that, the bitumen, in liquid form, is filled into the coated cavity. Additional layer of bituminous and polymer film are then consecutively laid over the bitumen-filled cavity, encapsulating the bitumen thereto. A system to form such bitumen package is also disclosed herein.
