That's not what we've seen locally. In two local trails, the
destructive culprit seems to have been tree roots running laterally
under the trail. Yes, it took a while - more than ten years - but the
roots have raised series of sharp "speed bump" ridges, probably 2"
high. One trail has just a few of them, spaced so I can hop over them
on the bike; but the other has such a dense network that the only way
through is to stand and slow to about five mph until one's past that
section.

Same here, 11 or 12 years before some sections required repaving.  The
layer of asphalt and the structure underneath seem much thinner than in
actual roads.  The other problem is that the trails don't seem to be
cambered at all.  Water (or ice) just sits.
