We've been asked to look at replacing the existing approx 40mm thick bitmac which overlays cobbles on a town centre side street. I'm conscious that this might not be as straightforward as planing off the existing bitmac and simply replacing, can anybody point me towards any guidance or spec for the process, or how to prepare the cobbles for being overlaind, thanks in advance?
