| In 1957 I excavated and poured a drive 130 feet long. I didn't have much gravel so it was poured nearly the full thickness of 1x8 form boards. It has rerod and wire mesh. It got truck traffic (tandem axle trucks) for the next 30 years. Last I checked 5 years ago, it hadn't cracked yet. It has cross seams every 10 feet with rerod connecting the slabs. That's in a St. Louis unincorporated suburb. My dad said it took real effort when the county widened the road and took out a slab or two. Their replacements have not weathered nearly as well.
In 1989 I prepared my new machine shed floor with packed sand (by my feet) fill to level it, and rerod plus mesh. It was sawn and has one crack but no offset at the crack. I specified 4000 PSI concrete I think. The crew wanted to know if I was going into the preparation business. They liked how it was done. There's a plastic film (silo cover) under the concrete too. Its about 5-1/2" thick.
With concrete over $100 a yard and #4 rerod under $5 a 20' stick rerod on 18" intervals doesn't add much to the project cost with labor costing as much as the raw materials.

Wire mesh or re-rod for concrete?
