surfaces question

A while back (before I had to scrap and restart a fresh playset) I watched a tutorial on area bucket and they showed how to change the default asphalt to other asphalts. I remember him saying he liked "this dark asphalt" and sure enough I had that and liked it as well. Now I can't find the surface pack or where that dark asphalt came from. I think there were also sidewalk surfaces that could be used in there that I no longer have. I've searched and subscribed to all of the surface packs I could find and still nothing. Does anyone know what mod pack those surfaces are in?? Thanks!
