Concrete costs less in the long run!
Federally funded studies show that concrete Interstate pavements cost 13-28% less in the long run than asphalt Interstate pavements.
Recent University of Minnesota studies in Olmsted and Waseca counties show that the use of concrete pavement saved up to 19% in the long run over the cost of using and maintaining similar asphalt roads.
The same studies show that maintenance costs were reduced 75% when concrete was used to pave roads in these counties.
Advancements in concrete technology have reduced the cost of concrete paving while improving performance greatly; advancements in asphalt technology (so-called "SuperPave" mixtures) have increased paving costs significantly (even before considering skyrocketing oil prices) with only modest increases in performance.
