'gravel' is like rail ballast; a compacted surface ordinarily has a mix of fine gravel and even finer material such as sand, and is rolled. Americans will often refer to a compacted road as a 'dirt' or 'gravel' road but the difference is like night and day when you're driving on one!
I must admit, this one really got me. For much of life when I lived in New York state, where Kevin and I are from, locals called all unpaved roads "dirt roads". When I started using OSM, I realized that the definition of "dirt" here is closer to "ground" so I began to use either unpaved or gravel for the surfaces of rural roads in Alaska and Thailand. Eventually, I found out that gravel means the type of stones found on railroads, which is big chunks of crushed rock and that the surface of the improved roads I was tagging was actually surface=compacted with tracktype=grade2. The type of mapping I do is 90% armchair mapping so it's difficult to ascertain these characteristics so I default to surface=unpaved in most cases. Alaska is an exception because most rural roads below the tertiary class are well-prepared, unpaved compacted surface roads. These I feel confidant to tag with surface=compacted and tracktype=grade2 My 2 cents.
