Thinlays with NAPA President Mike Acott
For heavily trafficked roads,
Thinlays can be part of a staged
construction approach, where the
total depth required to develop a
Perpetual Pavement is built over
time. For example, a Perpetual
Pavement design for a road may
require 10 inches of asphalt.
With staged construction, the
pavement is constructed with
8 inches of asphalt and then
overlaid with a Thinlay at set
intervals to increase the structure
before distresses begin. Because
the structural increase happens
in parallel with the preservation
activity, the interruption for
drivers can be minimized and
agencies can plan for the expense.
As the industry works to
implement performance testing
for asphalt mixtures, we expect

to see additional innovations for
Thinlays that optimize the use
of RAP, polymers, crumb rubber,
and mix type. Adjusting mixes
to optimize rolling resistance,
noise, and skid resistance will also
occur.
AP: What has been learned
since the PEC market research
that gives insight to Thinlay
future applications?
Acott: The market research I
mentioned earlier helps inform
the research plans of the
Pavement Economics Committee
and the communication of
research findings, as well as the
deployment activities overseen by
the Asphalt Pavement Alliance.
For the pavement preservation

marketplace, these needs of the
public and road owners are met
well by Thinlays, which can costeffectively return a pavement
to a high level of performance
and drivability with minimal
construction delay. Knowing the
needs of today's road owners, and
the budget stresses they face, I
am certain that Thinlays will be
used increasingly to preserve and
maintain pavement assets and to
ensure a smooth ride for drivers
in a cost-effective manner. AP
To assist in the deployment of
Thinlays and the use of best
practices, the National Center for
Asphalt Technology is developing
a Thinlay guidance document,
scheduled to be published in late
2017 this year.
