Clips are not offered for this film: a public-domain mark that nothing bears out (no year, or a year no US term has left).

Not offered: its uploader or archive marks it public domain, and nothing the site holds bears that out (its record gives no year, or a year from 1978 on, which no US term has left), so where it is free is not known. Unclear is not offered. Open it at the Internet Archive.

Making Small Rocks... Out of Big Rocks

Demonstrates the use of a mobile rock crusher (Forester C-2000) for in-place road reconditioning on very low volume roads. The crusher demolishes large rocks and produces a viable aggregate that can then be used as the road surface -- particularly useful on roads where the quality and expense of a standard crushed aggregate is not warranted. *Includes three demonstration projects and interviews with operators.

Human-made No record of this work says a model made it. What this means.
