Adding a drive

[Arcticdude]

I'm looking at finishing out the rest of my drive for my birdhouse. Here's my dilemma:

The original drive was done with 6" 3500psi concrete and 3/8" rebar on 24" OC. It cracked the first time I drove over it (this was AFTER it had cured for at least 30d). It now has numerous cracks in it and has been driven over about 30 times total.

So in considering the new drive, I want to avoid that cracking. I fully understand that some cracking is inevitable, especially with the spongy soil I've got, but the parking slab is subjected to MUCH more long term weight and only has a few cracks in it, all of which are due to soil, not bus weight.

I'm being told that wire mesh will help avoid the cracking, but not finding much corroborating evidence to back up that claim online.

So do I stick with the rebar or try the wire mesh? The drive will not normally have anything parked on it and the heaviest thing driving across it will be the bird.
