Roadway construction and method therefor
A roadway has a containerized roadbed of a width sufficient to support a
road surface and a depth sufficient to extend below the frost line of the
earth in the area; the containerized roadbed has an outer enveloping wall
of suitable elastomeric material which contains therein suitable filler
material such as, for example, dirt, sand and rock; the containerized
roadbed is evacuated to remove moisture from the filler material and
hermetically sealed; a suitable road surface, as for example a layer of
concrete, is formed atop the containerized roadbed.
