[QUOTE="CHenry, post: 3589996, member: 6281"] From a guy who knows a little about building interstate highways, the answer is no. Unless you plan on parking a 15k lb truck on it. Use the standard 3500 psi with 3/8" rebar spaced 16"-24" both directions. and 3.5" deep for the portland. Screen mesh can be used even cheaper and still last a good long time with average size 3500 lb cars on it. Cut it 1/2' deep every 10' also. Control cracks is all that is, it will crack but you will never see the cracks under the sawcut. I poured 3500 psi for my shop and 3 years later decided I wanted a 10k lb lift on it so I cut cores in the area I wanted the lift. It needed to be a min 3500 psi and 4" deep. it crush tested in the materials lab at 4900 psi and was 4" deep. I paid for the basic and got premo [/QUOTE]
