After the brutal winter, my wife and I found several locations on our driveway where the concrete is crumbling. This is the worst of them:
In the past, I have used self-leveling concrete caulk similar to this to fix damage like this:
However, I am concerned that due to it being near the edge that the caulk will fill in the crack between blocks and possibly make the damage worse due to expanding and contracting of the concrete.
How should I repair this damage, short of replacing the driveway itself?
