Need to repair driveway? Advice needed

So we built our house about 4 years ago, and when they poured the driveway, where it meets with the blacktop street, they just poured about and inch of concrete over the asphalt about 4-5 inches out. Now that section is almost completely broken up in chunks.
My thought to repair this is:
1) rent a concrete saw from home depot
2) cut my driveway about 12" back from the road
3) cut out the asphalt where it meets the driveway, probably about 4-5"
4) dig out 10" deep
5) pour new concrete into the 10" X 20" X width of driveway section
So now there would be no overlay of any materials, just a 10" deep concrete wall that meets up with the street.
Does this seem like it would be sufficient?

10” is unnecessary. 5-6” is sufficient residential at the street.
Think about renting a hammer drill as well to dowel in 1/2” rebar. (Use a 5/8” bit) no less than 24” on center.
Use epoxy in holes.
Add mesh
None of this is necessary but if you are taking the time to fix it, push a bit more into it and it’ll have a better chance to last.

I agree with the above except that depending on the existing driveway thickness, it may be difficult to drill holes without cracking the concrete. If you're going to use #5 bars, the hole will need to be 3/4" or larger. If your current drive is 4" thick, that doesn't leave much room above and below the hole. Hopefully you have wire mesh in the concrete now. If you can break out a small section to determine the depth, then set your saw to cut to just above that level. Break out the rest of the concrete and then overlap new mesh onto the existing and pour your new section.
Hopefully that made some kind of sense.

Thanks guys.
Sounds to me like you’re saying don’t cut all the way down the existing slab. Just enough to expose the mesh, then break up the concrete still attached to the mesh and then I’ll have mesh from the drive way to tie the new pour into?

That's what I would do

Yes, try to leave the old wire in place. They is about a 100% chance the old wire will not be level across. Get some wire ties and some concrete wire, tie it to the old, then pour.

This is a lot harder than you think. And if you don’t cut all the way through the concrete, you run the risk of transferring a crack to the concrete that you plan to keep. How wide is the apron?

Yeah I agree trying to bust the concrete off the wire will be dang near impossible.
If it were me I would cut out the section like you discussed but try to dig out under the road and under the existing slab some to make an irregular shape to help it lock together also rough up the mating pieces as much as possible the drilling and rebar is a good idea but again as pointed out probably difficult.

Whenever I have a spot in a concrete repair where I have two parallel cuts like you’re talking about here, I try to get make them at least 18” apart so that I can get a hammer drill in there. That’s why I asked how wide your driveway was. For a twenty foot wide apron, you’re only looking at an additional 5 bags of quikrete to mix. Again if you’re going through the trouble, a little bit of extra work will stand up much longer.
