What are the layers in a roman road?

In: Roman Empire [Edit categories]

Answer:

After digging down to the prescribed depth, the earth was leveled and pounded tight. The first layer was called the "statumen" which was of stones "of the size to fill the hand". This was covered by the second layer called the "audits" a concrete of broken stones and line. Over this was the "nucleus", a bedding layer of fine cement made with pounded potsherds and line. On top of this was the crown of the road, the "dorsum" which was made of paving stones which were slightly raised in the center so the rain water would run off.
