OTT - Weight Concrete supports
 

Can someone tell me how much weight (truck loaded w/ dirt) can drive on our concrete drive without cracking it.
Drive has 4-5" of concrete over 5" gravel base over 5-6" of 3" stone.

Thanks,
Rick

If it's in good condition with a well built base and cured concrete, the slab will take a fully loaded semi a couple of times. It's the repeated traffic that'll break it. If they need to drive over it repeatedly, just have them tip the first load right on the drive. Level it off and then drive on the dirt. This will help distribute the load.

Thanks Cord,
It is fully cured and this is a one time deal.

You've got a very solid base and sub-base. I wouldn't worry at all. The residential asphalt street in front typically won't have as much bearing capacity of your driveway.

Thanks for the response guys!
