Depends on the type of cracking. If it is due to subgrade failure you have to dig it out and put in compacted gravel. If it is due to slippage, that will likely be an issue with the new paving as well and there is no simple treatment. If it's from the asphalt oxidizing and getting brittle, they just need to prestrip the crack with a suitable fabric.
