They use prepositioned dowel rods located where contraction joints will go and ZERO wire mesh. The stuff is junk.
Just to clarify a bit, a modern highway has 1/2 inch (I think) rebar about 12 inches or less apart in the WHOLE length of the pour. Isn't that right ?
I don't think anyone here was suggesting that the commonly used fence wire mesh would be appropriate for a real highway. And most of us are suggesting that it really isn't appropriate for anything except maybe a sidewalk.
I've seen some reinforced PCCP, but can't remember where.
Typical concrete pavement design for highways or runways is unreinforced save for tie bars at the longitudinal jts and dowel bars at the cjs.
