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 shows 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.
Concrete
lasts longer with less need for maintenance and repair!
No
potholes - so concrete pavements stay smoother longer.
No
ruts form to fill with water and cause wet weather accidents.
Fewer traffic interruptions for repair and maintenance.
M/DOT
reports that the average life expectancy of their concrete
pavements is 27.5 years before repair while asphalt pavements
have an average life expectancy of only 15.5 years before
repair
Federally
funded studies show that concrete Interstate highways
around the U.S. last about 2.5 times longer on average
than asphalt Interstate highways.
New
Minnesota concrete pavement designs are expected to last
for 60+ years with minimal maintenance.
Concrete
costs less for users, too!
Heavy
trucks get up to 20% better mileage on concrete.
Better
long-term performance means fewer interruptions and lower
user costs.
Concrete
roads are not subject to spring load restrictions that
increase the number of truck trips or driving distances.
Concrete
is quiet!
After
years of testing and research, M/DOT has adopted concrete
paving designs and techniques that make concrete roads
as quiet as most asphalt roads, while maintaining superior
skid resistance.
Concrete
is environmentally friendly!
Concrete
is completely recyclable.
Concrete
doesn't release odorous petroleum products into the air.
Concrete
conserves oil, which is used to produce asphalt pavements.
Replacing
asphalt pavements with concrete can help to lower summertime
temperatures.
Concrete
reflects sunlight instead of absorbing it.
The
"heat island" effect seen in large cities
has been attributed, in part, to the use of asphalt
pavements.
Concrete
is aesthetically pleasing!
Concrete
pavements have a clean appearance and brighten neighborhoods,
both day and night!
Concrete
can be colored and textured to produce attractive designs
and patterns
