Perpetual Pavement Awards
Built to last, Perpetual Pavements save taxpayers time and money

"

ne of the keys to sustainability is long
life," said Amy Miller, P.E., national
director of the Asphalt Pavement
Alliance. "Asphalt roads can be
engineered to last indefinitely with
only routine maintenance and periodic surface
renewal. These pavements are called Perpetual
Pavements."
The advantages of Perpetual Pavements are
significant. Life-cycle costs are lower because
deep pavement repairs and reconstruction are
avoided. User delays are reduced because minor
surface rehabilitation requires shorter work
windows and can avoid peak traffic hours. And
there are environmental benefits because minimal
rehabilitation, combined with recycling any
materials that are removed from the pavement
surface, reduces the amount of material resources
required over the pavement's life.
Since 2001, the Asphalt Pavement Alliance
(APA) has recognized long-life pavements with the
Perpetual Pavement Award. The award is given
to state departments of transportation and local
agency owners for an asphalt pavement that is
at least 35 years old, has never had a structural
failure, and averages no fewer than 13 years
between resurfacing. The road must demonstrate
the characteristics expected from long-life asphalt
pavements: excellence in design, quality in
construction, and value for the travelling public.
Across North America, 118 roadways have been
honored with Perpetual Pavement Awards.
Each year, engineers at the National Center for
Asphalt Technology (NCAT) at Auburn University
evaluate pavements that are nominated for the
Perpetual Pavement Award. For 2016, ten nominated
roadways were validated for their long-life asphalt

ALABAMA

State Route 3 in Morgan County

The Alabama Department of Transportation earned
a Perpetual Pavement Award for a 2.5-mile section of
SR-3 (US 31) in Morgan County, between Hartselle and
Decatur, Alabama. This is ALDOT's eighth Perpetual
Pavement Award in 12 years.
The award-winning section of SR-3 extends from
milepost (MP) 350 to MP 352.5. Although there are
no early records available documenting the original
construction of the roadway, records do show that the
road was crack-sealed and then resurfaced in 1979,
adding less than 1 inch of asphalt to its structure. In
1992, ALDOT milled 2.5 inches of asphalt from the
road between MP 350 and MP351.99, performed cracksealing, and then laid two courses of asphalt pavement
mixture. In 1994, ALDOT did similar work on the
sections from MP 351.99 to MP 352.5.
Although ALDOT plans to micro-mill and resurface
this section of SR-3 in 2017, it has gone more than 20 years
without requiring major maintenance. More than 18,000
vehicles each day use this road - 4 percent of which
