How do I bridge tarmac drive down to garage which is lower level information and advice on general building topics, builders merchants, problem builders, DIY Stores etc....

I'l want to resurface my drive. With cold recycled planings. The section to the just outside the garage is in decent condition and is level with the floor of the garage and drain.
About 1.5 meters back from this, the concrete is in bad shape at the top, so needs about 50mm to 70mm of new tarmac applying to it and so does the rest of the drive (about 15 sqm of existing drive and I'm extend the drive by another 15 sqm around it on 3 sides).
I'm wondering how to join the higher section which will need at least 50mm adding to it, with the section outside the garage which is already flush with the garage floor so can't go any higher.

Is the best option to cut a 2ft channel out and bridge the new higher tarmac level ( 50mm higher further up the slope) with the concrete outside the garage. It would mean having a bit of a slope.
Or take up all the concrete outside the garage? I don't want to take up all the concrete on the drive as that would be too costly in time and money.

If I go for a transition channel, do I do this directly outside the garage or where the concrete starts looking shaky -about a meter further back.
(Sorry I can't upload an image I get error messages saying either too large and it's on my lowest camera setting or can't determine size if I try to alter the image)

To bridge a tarmac driveway down to a lower-level garage, you’re basically creating a smooth transition ramp that handles both vehicles and water properly. The key is getting the slope, base strength, and drainage right.
