Estimated Average Percent RAP by State, 2015 Construction Season

Reclaiming and
reusing the asphalt
cement and
aggregate in RAP
and RAS saved
about $2.6 billion
in 2015 compared
to the use of virgin
asphalt binder and
aggregates.

were used as aggregate, cold mix,
and other road-building activities.
The survey also found that at
year-end of 2015, about 85 million
tons of RAP was stockpiled for
future use across the country.
Reclaiming and reusing the asphalt
cement and aggregate in RAP and
RAS saved about $2.6 billion in
2015 compared to the use of virgin
asphalt binder and aggregates. This
helps keep asphalt pavement mixture
costs competitive and allows road
owners to achieve more roadway
maintenance and construction
activities with limited budgets.
Producers were also asked about
ground tire rubber, steel and blast
furnace slags, cellulose fibers, and
other waste materials repurposed
into pavements. Although national
estimates of their usage were not
calculated, respondents reported
using more than 1.1 million tons
of these materials in 2015 in the
production of about 8 million tons
of asphalt pavement mixes.
In addition to increased use of
recycled materials, asphalt mix
producers continue to increase the
use of energy-saving, warm-mix
asphalt technologies. In 2015, 119.8
million tons of warm-mix asphalt was
produced - nearly one-third of total
asphalt pavement mix production.

This is a 5 percent increase from 2014
and a greater than 614 percent increase
in the use of warm mix since 2009, the
first year the survey was conducted.
"The use of warm-mix asphalt
technologies is becoming commonplace.
In 14 states, more than half of all asphalt
pavement mixtures were produced as
warm-mix asphalt, and in four of them,
more than 75 percent was produced
as warm mix," said NAPA President
Mike Acott. "This said, there is room
to increase its use, and we expect road
owners to continue to embrace these
technologies for their construction
and performance benefits, as well as
the energy savings they bring."
The survey was conducted during
2016. Results from 214 companies with
1,119 plants in 48 states and Puerto
Rico, along with data from state asphalt
pavement associations for 33 states,
were used to compile the report. A

Pavement Industry Survey on Recycled
Materials and Warm-Mix Asphalt Usage:
2015 (IS 138), including a state-by-state
breakdown of information, is available at
