Tarmac - On concrete

[eletricalone]

I am new to the board and a novice. does anyone know if it is possible to lay tarmac on top of existing concrete drive? any views would be appreciated.

How about viewing the main website where this question is answered in some depth?

yeah its no problem use a good leotac product to stick your bitmac down,most roads are done in this manner when overlaying concrete.would help if concrete was cracked because tarmac is a flexiable material and concrete is not(when over laying with bitmac over concrete this is called composite driveway/highway). i take it you will be using 6mm tarmac? are you going to lay it yourself?

I worry about well-intentioned DIYers and amateurs who claim they are going to lay their own bitmac. It really isn't a task that's suitable for the inexperienced, mainly because it's an unforgiving medium.

If you make a mess of, say, block paving or patio flags, they can be taken up and re-laid, but bitmac doesn't give you that option. If you don't get it right first time, it never will be right.
