said by F100:Also, what's the best way to fill the crack between the driveway and the concrete pad of the garage? That is where I am loosing some material.
If its only a 1/2" or so, ask them for a quote on a heated crackseal job. Fill the whole void.
You can also buy a water activated cold patch from SealMaster. Its not cheap but it is DOT approved to pave over without removing. Regular cold patch needs to be removed and filled with base.
