Your current temp is right now around 32*F, your lowest temp over the next 48 hours doesn't show below 25*F. Your most effective choice based on cost, temp, time frame, and effectiveness for your own traction to complete the job is going to be rock salt.
You didn't give very specific details about the slope and the amounts of snow and ice pack or the overall length of the drive, but this method will work regardless, unless the snow is higher than your axles. I'll assume each leg of the drive doesn't exceed 100' & I'll also assume that maybe you can't see past your hood when driving upward.
Based on that...one ton of salt (bulk) approximately $75-85, would be more than enough to get it to bare pavement pending the amount of time that you have. Again assuming, that you can't climb the drive in forward or reverse, you can start by manually applying salt in two heavy tire width paths where you would be driving. Don't do the center yet. The material should be at it's heaviest at the highest points of the drive and to the higher edges. This will do two things...1. giving you traction, something your tires will have to bite into, 2. by driving over a few times, the salt will be ground deeper into the ice developing a slurry. As the slurry becomes more liquid, you should notice the width of those tracks begin to widen. You should also see where the salt water begins to start running downhill, with the heavier concentration near the top it will increase the melting down below. Water always takes the path of least resistance & will at some point find its way under the ice pack & eventually break the bond. Once you feel comfortable with driving on it (after the salt has had adequate time to work), you can begin scraping it down. The salt at this point in time should be below the higher snow, which would pose no problems as far it it being plowed off. Once you get the drive down to a manageable or reasonable thickness, you can apply a general coating to the entire surface area. If done right, you should have enough residual salt left on the drive, that will make your next plowing event more manageable. The more you can drive on it, the more you will accelerate the process. Obviously, the amount of material that is used will also be relevant as to how fast or how long it takes to complete.
If bulk salt is not an option for you, bag salt will work fine but only double or even triple the cost. If bags are to be used, best to just cut a small corner off the bag and spill it out in the same method. Too thin & too wide will take too long and possibly a lot more material.
Charge accordingly & good luck!
