摘要：
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.
