The constant freeze-thaw cycles and the thousands of pounds of metal moving over your driveway every day are going to damage it at some point.
This damage will normally show up as small cracks across the surface or small divots in the material, and it’s these signs of minor damage that really call for driveway patching.
Driveway cracks that are less than a quarter-inch wide don’t really indicate any deeper damage to the driveway surface and can be repaired easily with liquid crack-fillers.
Driveway cracks that are larger than a quarter-inch wide in your driveway or that are more than a few inches deep often signal more significant issues. Filling in those cracks will only temporarily solve the problem.
