We had a cherry picker type of thing with a platform coming down the long stretch of our tarmac cutting the neighbors trees leaning over our site few years back. The machine was stabilized by pads. There was a few pressure type marks left where the first pads were dropped down, after that sheets of ply were put between the pads and tarmac. The large rubber wheels did no damage nor the weight of the machine.
If the mini digger on metal roller (not the right lingo), it will grate along your drive as Iv seen it done on main road outside neighbours house where it went from one house to the one across the road, council had to retarmac.
