What would be an acceptable road grade? Would 10% be reasonable / allowable for a gravel road?

I think you'd be OK with that.
There are paved roads at 10% and even more.

Rick,
I think it will work out to 12% (36" run, 4.5" rise approx.)

Only in Louisiana. I just HAD to stop and get a pic of this for my model railroad buds. A grade sign for a bump.

Tom, as you know some parts of the country have some really steep elevation gravel road grades. This Photo depicts typical grade breaks on a road with a long downhill slope. There are no exact formulas for spacing or size, but depending on slopes, traffic, volume of water, terrain, etc. this helps with a steep grade.
Although the photo shows the cross pipes at the road low points, cross pipes can be strategically placed and can be used to create grade breaks. These cross pipes can be installed to effectively change and lessen the grade. The road would be built up and over the pipe to create these grade breaks. This will help with road and ditch erosion protection, as well as ease the otherwise steep grade.

In New England, most zoning & highway standards try to avoid anything over 8%. This is less of an issue where it doesn't freeze/ice. On private property and before governments regulated it, anything goes. But people tell me you need a dozer to plow 15%, and a wise dozer operator to avoid killing himself while doing so.
