It's called chip seal and it's not intended to be used as a crack filler. Chip seal is intended to protect the asphalt road surface. A smooth layer is actually pretty nice to drive on (minus the noise). Sealing cracks with it, not so much.
It's not too often you see a smooth layer laid down on a good stretch of roadway. Lacombe County did a pretty good job with theirs tho. But during the install of it, it's a nightmare to be near. Unfortunately, this kind of thing seems to be the way road rehab is going. Too cost effective for places to ignore.
