Since temperatures have risen here in the last few weeks, the cement has returned to its original position, but it has left behind some imperfections that you'll need to shore up. After frost heave happens, you tend to see a lot of little hairline cracks that will start to form in the cement - seal those up once temperatures get above 50 degrees.
Your home may have this problem as well. On many driveways, between the driveway and the garage, there is an expansion joint. The joint is meant to be there so the driveway can't be pushed into the house. When frost heave occurs, it will be pushed up. You can't really push it back down, so the best thing to do in this situation is to try to cut off the excess expansion joint safely with a knife. Then, get some polyurethane sealant and apply it to the crack. Doing this sooner than later will help prevent against frost heave next winter.
