This doesn't seem to be a problem in practice, or rather, it's a problem we already live with. Roads and trails are already poured in layers, you can see this currently in Victoria park at the south parking lot the trail passes, they have only one layer of asphalt down, and there is a lip to the section where they have two layers.
