My 3 year macadam driveway is losing rocks in spots (forming little potholes, little because they are the shallow depth of lost single layer of gravel, see picture). The problem is that other rocks are now easily coming off around these spots.
Couple of questions - if you can tell from my photo:
Is this anything to worry about? or is this normal wear and tear
Is there anything to be done maintenance wise to avoid big repairs later?
Is macadam and tar-and-chip the same thing? Is it possible to tell from my photo?
