Using concrete slabs to "pave" some wet spots in a road.

I think some geotile fabric would be your friend. Put that over the mushy ground. That will help support the concrete.
By me, crushed shale is what many use for driveways. Our soil holds water. The ones that just layout the shale find it disappearing into the ground. While the ones that roll out the geotile have much better luck. These rolls sold at Lowe's, for one, come in 14'x 400' rolls.

To the OP, a lot of overthinking in my opinion. Some advice seems to think if you put those slabs in the world will stop turning. Me reading between the lines it sounds like you have a problem area but it’s not a huge deal. Dump those slabs in and see what happens.

I had success using concrete slab/chunks on a path that ran about 50 feet down the side of my barn. I first scraped it out sub level,so the slabs would end up at grade, then used sand and some gravel as a bed.

dug a drainage ditch on the low side, and filled it with fist sized chunks and gravel. Then laid the broken slabs in like mosaic tile, and drove back and forth with tractor.

Ten years later, it still works well.

The only solution may be a bridge.

The only solution may be a bridge.

With 6-8” ruts, you’re prolly right.

Any tips, tricks, warnings? Good idea bad idea?

Build drainage ditches both sides of the roadway, and use culvert(s) to move water across the road.
As said, stop driving in the "ditch". Drain the swamp and raise the grade.

I was at a chemical plant under construction in Russia last year and they used slabs of concrete that were approximately 6 x 12 (probably metric, but I don't think that way) to temporarily pave the roadways placing them side by side. Since there was nothing under the slabs they shifted every which way and made for the most God awful ride I ever had in a bus. The impressive thing was that I never saw a cracked slab.

I'm afraid without some form of bedding your slabs will create nothing more than headaches.

Hmm... this is what I was thinking:

I think I saw that on an episode of "Matt's Offroad"...

Excellent advice! Makes perfect sense.
The only problem is this area is along a creek and it floods 3-8 times a year. So unless I raise that area somehow it will always get wet and stay wet for awhile, generally most of the winter and spring.

Could you possibly run 2 layers of the slabs, maybe the first layer running in the same direction of travel as the driveway, and the second layer perpendicular or across the driveway, thus allowing one layer to help hold the next in place? Just a thought.

Do you think it would be taboo to use large pieces of asphalt in this system as well. Again, this is a wetland type area, is the risk of serious pollution an issue using old asphalt in a wet environment like that?
