One of the things my mate uses with his kato track to give the effect of concrete/paving area is using some spare paving and cobblestone paper that comes with the metcalfe card kits and it does look effective as well and it already has the print on it if you go for the cobblestones design.
The other option you can have which is the way I did with the old layout is to used plaster of paris spread over the lines. The only thing you need to make sure is that the plaster doesn't interfere with the rails itself otherwise it can be a real pain to clean out from the inside of the rails so it doesn't de-rail your locos.
