HOW FP 2 WORKS FOR YOU

NCAT Track Conference Will Provide Look
at Pavement Preservation Sections
BY DR. BUZZ POWELL, P.E.

P

avement preservation research
at the National Center for Asphalt
Technology at Auburn University
is a major part of the agenda for
the 2018 NCAT Test Track Conference
scheduled for March.
Held every three years, the Test Track
Conference is a forum that presents
research findings from the previous cycle
of accelerated pavement testing. During
the 2 1/2-day program, participants learn
about advancements in asphalt pavement
design, construction, technologies, and
maintenance that are cost-effective and
improve performance.
The conference also provides a valuable networking opportunity, and sets the
stage for further cooperation among federal, state and local agencies as well as
the private sector.
The 2018 Test Track Conference will
be held Mar. 27-29 at The Hotel at Auburn
University and Dixon Conference Center in
Auburn, Ala.

FOCUS ON PRESERVATION
The first day will focus on a test track overview and related research, and conclude
with a visit to the track. But the prime
thrust of the second day (Mar. 28) will be
pavement preservation, with technical sessions including an overview of pavement
preservation, construction of preservation
experiment sections, and an hour-and-ahalf discussion of pavement preservation
performance there.
That afternoon, discussion will cover
thin asphalt overlay (Thinlay) projects in
Tennessee and Mississippi, and will conclude with visits to preservation sections
on Lee Road 159 and U.S. 280.
We hope you will take advantage of
this extraordinary opportunity to see
firsthand the research going on at NCAT,
and be brought up to date. Online registration is available at http://ncat.us/

A similar conference profiling the
preservation experiment northern sections at the Minnesota Road Research

Facility (MnROAD) is being planned for
the fall of 2018.
NATIONAL PRESERVATION
EXPERIMENT
Full-scale accelerated pavement testing
(APT) has been conducted for predominantly southern states at the National
Center for Asphalt Technology (NCAT)
Pavement Test Track since 2000. The
Minnesota DOT's Road Research Facility
(MnROAD) has been conducting similar
research for northern states since 1994.
Today, these facilities are officially
engaged in a research partnership in performance of pavement preservation for the
first time. The objective of the preservation group (PG) experiment, in which FP2
is an equal funding partner with DOTs
from 15 different states, is to quantify the
benefits of pavement preservation on both
low volume and high volume roadways
with results that are practical and implementable in both northern and southern
U.S. climates.
As of Jan. 1, the number of ESALs supported since treatment placements totals
approximately 70,000, 830,000, and
1.4 million for Lee Road 159 northbound,
Lee Road 159 southbound, and U.S. 280,
respectively. The northern low-traffic sections support approximately 700 vehicles
a day, while the design vehicles for the
northern high-traffic sections are over
7,000 vehicles a day.

QUANTIFYING BENEFITS
Ultimately, the life-extending and
condition-improving benefit of the various treatments and treatment combinations
will be quantified in terms of pretreatment
MAP-21 performance measures.
Reduction in cracking is an example;
however, the methodology will also be
applied to both roughness and rutting. The
main implementable product will be lifeextending and condition-improving benefit
curves for low, high, and accelerated traffic
in both hot and cold climates.
State agencies can then interpolate
between these plots for their particular
climate and traffic level. Additional pavement condition data, which are relatively
low-cost now that sections have been
installed, will be collected from both the
southern and northern sites for many years.
Other deliverables will include guide
construction specifications (e.g., quality
testing for micro surfacing), best practices
(e.g., quick reference materials for new
inspectors), and support for implementation (e.g., training).
