A bulk material such as garbage is introduced into a hopper inlet (14) of a compactor (12). A piston (18) in the compactor moves the bulk material out from the compactor (12) into a vault (26). In the vault (26) the material is compacted against a barrier wall (66) until an initial body of compacted material is formed between the inlet and the barrier wall (64). Then, the barrier wall (64) is retracted up into a position substantially within the plane of the top wall (32). Then, the compactor (12) is operated to compact additional bulk material (24) into the vault (26), and at the same time move the material (24) lengthwise through the vault (26). When the vault (26) is sufficiently full of compacted material (24), the vault (26) is expanded for the purpose of enlargening the cross sectional dimension of its inner space. A cargo receiving compartment (30) of a road vehicle (10) is positioned in registry with the outlet of the vault (26). Reciprocating floor conveyors (RF1, RF2) in the vault (26) and the cargo receiving compartment (30) are operated together for moving the body of compacted material (24) out from the vault (26) into the cargo receiving compartment (30) of the road vehicle (10).
