The Department shall determine a quantitative rating on the pavement condition and ride quality of every highway in the primary and secondary state highway systems at least once every five years, using metrics generally accepted in the United States for this purpose. The Department shall post these ratings on its website, organized by transportation district, updated at least quarterly, with interpretive guidance, identifying each (i) primary and secondary highway or segment thereof that has been rated, the pavement condition and ride quality rating given, and the date it was last rated and (ii) primary or secondary highway or segment thereof that has not been rated and the approximate date, if available, that the rating is scheduled to be made.
