A doser mechanism includes a cylindrical shell, an auger conveyor, and a check valve. The cylindrical shell includes a hollow cylinder and an end plate. The hollow cylinder at least partially defines an internal enclosure extending between first and second ends of the hollow cylinder, a first opening at the first end, and a second opening through a thickness of the hollow cylinder. The end plate covers the second end. The auger conveyor includes an auger at least partially extending through the internal enclosure through the first end. The check valve has a valve member configured to selectively cover the second opening. The check valve may cause the valve member to move between a rest position and an open position to cover or expose the second opening in response to a magnitude of a force applied to the valve member from the internal enclosure through the second opening.

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.
