摘要: |
Because of a combination of circumstances, there is an over
abundance of small-diameter timber available in the United
States. There is low demand for this material because it has
low value. One way to increase the value, and therefore the
demand, for this material is to develop or expand markets
where the material can be used. We looked at markets where
little or no machining would be required before use because
this would make it more feasible to use small-diameter mate
rial. One such market is that of wood posts in highway
applications. In this study, we gathered information on the
current use of posts, both wood and those made from other
materials, used in highway applications. Information was
gathered using a survey of Department of Transportation
engineers from across the United States. We then analyzed
the information to assess the possibility of increasing the use
of small-diameter timber in the highway application market.
We found many opportunities for ways this market could be
expanded, but we also found challenges to increasing this
market.
