In
Australia, basalt and similar rocks are quarried wherever they are found, and transported considerable distance, to form the surface of "gravel roads", because it is the best rock for this purpose. It is commonly called "blue metal", although it is stone, not metal, because of its typical dark

The suggestion that the logger get free timber is misleading. The value of timber as appraised usually assmumes that there is access to it. If building the access is expensive, it may consume most the the value of a particlar harvest tract, but that doesn't make it free to the contractor. the

A gravel road seems at least superficially very similar to a macadam road, these both being roads of small rock over dirt. Would be good to see the distinguishing points (I believe it is that macadam is specifically crushed rock, and gravel is any small rock of the appropriate size) expanded on.

I'm planning on adding to the
Construction and maintenance sections, along with adding some stats, and perhaps also including a section on gravel road classification systems. If anyone has thoughts or directions that could be added, please let me know on my talk page!

contractor ends up being a road builder who gets paid in trees instead of cash. Those aren't free trees. when done, the landowner has a road that is available for recreational use, firefighting, and access to nearby stands of timber for forest management activities.

These adverts suggest metal is larger than gravel, but variable in size - "Contract No. 351— Breaking and
Delivering some 2425 cubic yards of Blue, 2in Metal, and Carting some 808 cubic yards of Gravel", or 2½in, or 1in.
746:
Thanks for the
Direction! I have some stats from the CIA world factbook but i'm concerned as they're not specifically gravel roads (they could be dirt). Would you think a table would be a neat addition?
724:
A section on the extent of gravel roads by country would be interesting. In
Australia gravel roads form about 30% of the total and earth roads 50%. In New Zealand about 60% of local roads are unsealed.

530:. A 1912 New Zealand report said, "Some 64 yards of metal and about 3 yards of gravel have been put on the road." Does anyone else think the distinction should be clarified?

The introduction says, "In New
Zealand, and other Commonwealth countries, they may be known as 'metal roads'." However, it seems that some sources distinguish between
