Coal is not used to make roads. However a coal derived product is used in road construction.
When you distill coal, the final fraction is a thick black gloopy substance call "tar". Tar is used to coat small stones and when applied as a road surface makes them stick together and waterproofs the road. This was invented by a Scotsman called Mr. McAdam - the road surface is called "Tarmac".
