President's Perspective

Quantifying the Environmental Benefits of Asphalt
When it comes to knowing what
goes into its products, the asphalt
industry is already transparent. Mix
designs and job mix formulas are
developed detailing the percentages
of liquid asphalt, RAP, fine and coarse
aggregate, and aggregate type - all
well-established materials understood
by our customers. There are very few
secrets or special ingredients in asphalt,
unlike the products produced by many
other industry sectors.
Environmental product declarations
(EPDs) take this existing information
one stage further and help to quantify
the environmental characteristics of our
material. While not every construction
material or sector is being asked for
EPDs today, the expectation is that they
will become increasingly more common
in the coming years.
To prepare the asphalt pavement
industry to meet this future need, NAPA
has developed the Emerald Eco-Label,
a tool that makes it easy to produce
EPDs that reflect the environmental
characteristics of the specific mix
and the plant where it is produced.
For example, it will help the industry
quantify the environmental benefits of
using recycled materials, particularly
reclaimed asphalt pavement, as well as
the energy savings provided by warmmix technologies.
Over the past decade, the asphalt
pavement industry has made significant
strides in the use of these materials and
technologies, and EPDs help make sure
we get the credit we deserve.
For example, during the 2016
construction season, warm-mix asphalt
made up nearly a third of all asphalt
production in the United States. An
EPD helps make clear how using warmmix technologies to reduce production
temperatures reduces the amount of fuel
needed to produce each ton of asphalt
paving mixture and the corresponding
reduction in environmental impact.
Similarly, an average 20.5 percent
RAP was included in asphalt pavement

mixtures in 2016. An EPD shows the
reduced environmental impact of
using reclaimed and recycled materials
compared to virgin materials.
Over the past decade, green
construction ratings systems, such as
the U.S. Green Building Council's LEED
program, has grown notably. As of
year-end 2015, nearly a quarter of total
commercial square footage in the 30
largest markets in the United States was
LEED certified.
Publicly owned buildings have
long been required to meet green
construction standards, but now
local governments are encouraging
developers to apply green construction
practices to all projects, commercial
and residential. Miami Beach, Fla.,
for example, levies a fee of up to 5
percent of total construction costs on
structures larger than 7,000 square feet
unless they are LEED Gold certified.
For green construction ratings systems,
EPDs are an increasingly important
requirement. While porous asphalt
pavements continue to earn credits for
low-impact development and rainwater
management, other credits within
these systems are now based on the
availability of EPDs.
Emerald Eco-Label EPDs are fully
compliant with the ISO 14025 and
EN 15804 standards, which allows
asphalt mix producers to provide the
standardized, third-party verified
documentation needed for a project to
earn a full credit under LEED version 4.
Beyond LEED, the Green Building
Initiative's Green Globes, the
International Green Construction
Code (IgCC), and the Institute for
Sustainable Infrastructure's Envision
system all include incentives for
projects to use EPDs. They are also
used in the Greenroads rating system
for transportation projects, and
FHWA's INVEST sustainable highways
self-evaluation tool is working to
incorporate EPDs in a future release.
