Abstract: The present invention describes a method (600, 600a) of forming bitumen bags (605) for packaging bitumen products into blocks or slabs. Each block/slab of bitumen (200,200a,200b,200c) is encapsulated in the bitumen bag, which is composed of a bitumen compound (160). The bitumen compound (160) is made up of about 10-30% by weight of natural bitumen and about 5-25% by weight of a synthetic rubber polymer and copolymers. The bitumen compound (160) is melted with the bitumen content and is fully miscible with the molten bitumen, leaving no residue but enhances the physical properties of the resultant bitumen mixture.
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.

Abstract: The present invention describes a system (100, 100a, 100b) for dispensing and packaging bituminous products into blocks or slabs. Each block/slab of bitumen (200, 200a) is sealed by a bitumen compound film (160). The bitumen compound film (160) is made up of about 10-30% by weight of natural bitumen and about 5-25% by weight of a synthetic rubber polymer and copolymers. The bitumen compound film (160) is melted with the bituminous product and is fully compatible with the molten bitumen, leaving no residue but enhances the physical properties of the resultant bitumen mixture.
