It's a layer of tar sprayed on the road surface with gravel laid on top of it. It's rolled into the surface by cars and trucks and sometimes heavy machinery. After a few days the loose gravel is swept off. The problem is that the loose gravel is like riding on ball bearings... Tough on single track vehicles. The freeze-thaw issues of winter make this sort of thing necessary or road have to be repaved in 5-10 years.
Googling "chip seal" and looking at the images will show you how it's done.
