WoundUp those look like the bridge tiles talked about in the other threads just painted white to keep them cool and to keep them from expanding and shrinking in different temps. I have some cans of the glue used to adhere them to the deck at the shop I'll get some pics for you later
strange, I took this picture. Tiles are set in tar, yes. Not sure what exactly the tiles are but I have seen them many times before. Yes, they are painted, it is a 40 young brothers, and the tiles are what ever they were using back then.
