Help - tarmac driveway repair

[glasgowdan]

I've removed a car port and the base was a big raised slab of rubble, bricks, cement and slabs. This has left a 10m2 hole that I want level to use as driveway space. Can anyone advise on what would be the best course of action here please?

I don't mind it being visually different, just durable. I appreciate any repair may allow water in the edges and freeze/crack the tarmac over time.

Finding someone to supply 3t of asphalt is not proving easy.

Would it work if I continued excavating to 250mm, lay membrane, whack in 150mm type 1, 50mm builders sand and laid large concrete slabs on this sand with the joins brushed in with sand, or is concrete under the slabs really the only way to go about it? If so, I'll hire someone in to do it all.

Thanks

If you want to lay slabs then laying them on fine concrete or a good 50mm bed of grit sand mortar is the way to go.

If you cant get it bitmac'ed and don't mind the look id put in 100mm of subase and then 125mm of poured concrete if it was my house.

It's not perfectly level, would concrete still work?

Yes no problem, concrete can be finished to fit any variations. The one thing it wont deal with well is a big dip that would form a pool.
