The Historical Construction Equipment Association (HCEA) is a non-profit organization dedicated to preserving for public education the history of the construction, dredging and surface mining equipment industries.

The Koehring rotary grader from the early 1920s is the indirect ancestor of today’s milling machines. Capable of loading 60 to 100 cu. yds. per hour, it could handle macadam pavement or dirt, and an optional screen could separate out aggregates from the macadam. The discharge conveyor could be set to either side of the cutting wheel, and cutting depth was two in. to two ft. It was steered by operating one crawler to pivot on the other.

The Barber-Greene 879 paver was one of the first successful asphalt pavers to work independently of forms, and it established the basic design for all such machines into the present day.  This is the second version, an 879-A.
