Drive way ? repairing blacktop

[tommymac]

Our driveway had a small bump in it since we moved in nothing huge maybe 6x12 inches and only an inch or so high. Over the last few weeks it has been getting higher. there is a crack in the middle of it as well. Not sure why its pushing up, but is this something I could just break up and resurface temporarily. We were hoping to ge tthe driveway redone in 2 or 3 years and hoping this doesnt speed up the process.

its not exposed to a lot of sunlight, is not too far from the house and doesnt have any heavy weight going over it aside from my bikes occasionally, the cars are never up in this part of the driveway. And with the house jutting out its not super exposed to the elements compared to parts of the driveway further from the house.
