Paving over tarmac?

Postby benmann » Sat Jun 23, 2007 9:13 am

I have an old tarmac driveway that I want to pave over. Can I lay the slabs of a thick enough bed of sand and cement (8 to 1)? How thick would this need to be to withstand the weight of a car and do I need to seal or bond the concrete to the tarmac? Cheers!
