Bearing weight of Pressed Council Slabs

[Ferdinand]

Does anyone have any indication of what sort of weight will crack a Pressed Council Slab (ie the 2" things that cost next-to-nothing on Ebay) laid on a gravel base?

 

I am wondering how safe it is to lay a row of these on top of a gravel drive as a path, which would be down one side of the drive for ease of use by postmen etc and only need to be driven on when particularly wide vehicles come into the driveway.

 

I'm think that anything car or 4x4 or transitsize will be fine, but I am unsure about 3.5-7.5 tonner, larger lorries or 4/6-wheeler tippers.

 

Thanks

Well I used a couple to span a low spot on a temporary access as a bridge. Eventually cracked but that was with a loaded 3.5t on top. Under a full bed these are about as strong as slabs get I think. Loads of paths don't in them and I've seen grab lorrys and all sorts on top. If your gravels nice n flat. Perhaps a bit sharp sand n cement to blind gravel then you will be well ok
