Unexpected Consequence
I had the same thing with my last truck. I have some divots at the end of my driveway now as well as a nice indentation going into my pole shed.
It's sad to see but many driveways aren't meant for the weight of these things.

I have a plastic pipe through the ditch in my front yard along the road, when they built the house they paved asphalt over the plastic pipe to make the driveway, needless to say the asphalt is all chunked up because every time I drive over it there's flex. It's a perfect line right over the pipe too, well defined, uniform area of destroyed pavement.
So yes, these things are pretty stout, huh....

Wow...these trucks are massive, but shouldn't have cracked that concrete. There must have been a thin spot under the concrete. 4" will support these trucks. I bet when you patch that you find the concrete thinned out there or an air pocket under the concrete.
I'm guessing air pocket.
I discovered a section of mine was elevated 1 1/2 inches from the dirt.
I'm sure it had been that way for a long time and I was impressed the concrete didn't fall apart long before.
Of course we're talking about 1989 materials before everything became disposable.

4" of concrete will definitely support these trucks. The problem is somebody used 2x4 lumber to form that up ( 2x4s are really only 3.5") and then did a poor job of raking out the gravel under the concrete. Or worse put no gravel under the concrete. When you tear it out, You will find the cracked concrete is probably 2.5" thick.
The other possibility is with no gravel under the concrete, Water seeps in and freezes in the sand/soil under the drive water during the winter and heaves the concrete. After the frost is gone, you drive over it and it breaks because there is a void under the concrete.
