I was making a muck load from a wreck at a crossing for an MOW car, and wanted to include some damaged pavement. I used joint compound, flat black latex paint and sand, to make a mixture, and spread in on some wax paper to dry. I painted double yellow lines in the center, and a white line on each edge. I then broke the dried road section into chunks. This made a rather realistic looking road before I broke it up. There is a guy, Wilbur G Snyder, on several of the Facebook train forums who recently posted a short tutorial for making roads from thin cork sheet.
