I don’t think you could do the repair with asphalt. I’m not even sure I’ve ever driven on a concrete road, as down here in New Zealand there aren’t any I don’t think.
The current repair practice is to pour tar on the asphalt road and then a coating of road gravel. It’s noisey, comes off when heavy vehicles use it, comes off with heavy usage or heavy breaking, comes off in hot sun and it’s utter trash. It’s cheap though!
you are describing an asphalt microseal over the entire road surface. they are describing sealing of cracks using asphalt "tar snakes". They address different problems.
Road resurfacing improves stopping distances and rough rides if the road is overall in ok condition. If the road has large cracks in it this does nothing
Tar snakes are used to seal cracks from water because after rain the movement of vehicles over the wet subgrade under the road creates a pumping effect that ejects subgrade material out from the cracks and causes potholes in the future.
Of course they don't add rebar to asphalt roads, that would be ridiculous. The sealant process is done manually, with some poor sod pushing a machine along each crack and injecting hot sealant which prevents further water incursion and the associated frost heave. That's partly why I'm so fascinated with it: some sections of highway are cracked everywhere, with hardly a square metre that doesn't have a crack running through it, and yet they're extremely smooth.
