Years ago my dad had a concrete/asphalt business. A lot of times we would pour concrete in someone's back yard for a garage or patio, which meant backing a concrete truck back onto an existing drive. That is a lot of weigh per square inch where those tires are resting on the concrete. To prevent the concrete from cracking, we would lay down boards for the truck to back up on, which spread out the weight from those heavy trucks. We never cracked anyone's drive using this method. We just built a pole barn with a concrete floor, and I have the toy hauler wheels parked on 2x8's to prevent too much weight from being placed on a small surface area. Concrete cracks, fact of life, it's gonna do it. But this is one method to allow it to crack where you want it to. (Expansion joints, etc) Lots of people here probably already know this, but for those that don't I'm just passing along what I have learned.
