It cost a lot just to remove the concrete, machine cost, material dump fee, transporting the material. You need a skid steer and dump truck or a skid steer and dump trailer and truck which will take several loads. And that's on a single resident home, 9ft wide...40 ft long common driveway. I ain't buying that. I wish they would come steal mine because I'm fixing to remove mine and pour a double myself on a weekend. Typical double driveway on a residential street is about $8k to R & R
