They seem to use a lot of concrete in TX, even parking lots are often paved in concrete there.
By way of comparison, VA uses very little concrete. I had read that VDOT doesn't like to use concrete because they've had bad experiences with it.
Perhaps VDOT ought to ask TxDOT how to make concrete work, or another of the other state DOTs that regularly use concrete.
(I can't say that VDOT's asphalt paving jobs are that great, either--common thing to see is chunks of the top layer coming off and forming a pothole).
