Bitulithic Mixing Machine
-
Description
-
Black and white image of an early street paving project. Asphalt is a form of bitumen, and this is an example of an early mechanized hot-mix asphalt paving machine. Rather than being the material which covers the road, the bitumen or asphalt is the cement which holds the road materials together. In this case, it was probably gravel and small stones, the 'lythic' (lithic) in the 'bitulythic' mixture.
