We recently moved into a new to us house. There are a couple of depressions in the asphalt driveway that I thought I should try to level with some bagged asphalt patch.
Maybe unsurprisingly, when I swept the dirt and loose debris out of one of them, I found that there was a hole straight through the asphalt and into a void in the soil below. I am thinking this is an animal burrow, since I have found another void just under the soil surface nearby which I was able to confirm is a burrow.
My thought is that I could break away an opening in the asphalt large enough to gain greater access, fill the cavity to the best of my ability with crushed stone and then cover with and tamp the patch material.
I realize of course that if there is a burrow that close to the surface, it may manifest in other locations over time which I'll have to address too.
Otherwise, does this seem like an okay plan? Or should I be looking to do something else? (Short of tearing up the driveway, re-grading and repaving..)

Possible causes: (not all of them equally likely)
I'd make a small effort to determine what's causing it, but at this stage I wouldn't make too much effort at that, and jump quickly to exactly what you are planning to do. If the situation returns I'd then dig it up and figure out what's causing it.
I wouldn't assume it's burrowing just because there is burrowing somewhere else. It's a clue. I have chipmunks, rabbits, groundhogs, voles, and hornets digging up my lawn constantly but I've never seen any of them burrow all the way under a paved driveway for no reason. Might be a question of Outdoors SE.
