Weird... the system they use here on existing roads the tanker/sprayer lays down the tar, chip machine runs right behind it. For just a top layer they can do 5-10 miles a day. They do it on both regular pavement and tar and chip roads.

A full strip (and improvements) and take almost as long as regular paving, but on existing roads they've found adding layers every 4-5 years extends the life for decades.
