Pavement Preservation Journal - Spring 2018 - 40

My research team and I have completed our first round of trips to the field
where we collected photographs of the
pavements, and locked-wheel skid test
data from pavement sections that contained a wide variety of crack sealant
application conditions.
The primary goal of our research project
is to develop guidelines for the NCDOT
when applying crack sealant to damaged sections. We are hoping to identify when crack sealant is negatively
impacting skid resistance by correlating

the locked-wheel skid test results to the
crack sealant patterns which are being
captured by photographs taken during
our trips to the field.
After we have the photographs and are
attempting to correlate skid loss to amount
of crack sealant applied, the perspective
of each image was edited so that it would
appear that we had an aerial view of the
roadway. Using the contrast of sealant
to pavement, it was relatively simple to
create a binary image of sealant versus
surface covered.

Starting at ⅝ of an inch, Thinlays are the pavement preservation
treatment designed to extend service life while improving performance,
friction, and drivability. These thin asphalt overlays provide longlasting smoothness and can be used to increase structural capacity,
providing greater value for your pavement preservation dollar.

We are hoping to find a correlation
between the amount of sealant applied
and skid number, thus helping create a
threshold for when crack sealant would
not the preferred preservation method,
and other preservation methods should
be considered.
HOW HAS YOUR PERSPECTIVE
CHANGED ABOUT OUR ROAD INFRASTRUCTURE SINCE BEGINNING OF
THE RESEARCH?
My perspective on road infrastructure has
changed significantly. Before starting in
research, I believed the general stereotype
that exists for all construction projects: they
take forever and cause unnecessary delays
for months at a time.
However, after going out to the field and
talking with different contractors and DOT
personnel, I learned that many pavement
preservation projects cause minimal delays
and in some areas are finished the same
day they start.
Contrasting the common stereotype, the
process of applying the crack sealant is
exceedingly efficient. I was surprised that a
procedure that took only a few hours could
not only extend the lifecycle of a roadway,
but also reduce the overall life cycle costs of
maintenance. The fact that this procedure
can move so quickly but also preserve the
life of the roads for years is extremely fascinating, and I look forward to learning more
about different preservation techniques as I
continue my graduate school career.
DO YOU HAVE PLANS TO CONTINUE
IN THE FIELD OF PAVEMENT
PRESERVATION UPON GRADUATION?
Moving forward, I hope to continue working
with different methods and techniques of
pavement preservation. I feel there still is
more to learn, and I plan on doing so by
either working for a private design firm or
a department of transportation.
Although I am thoroughly enjoying my
work with preservation, I am also interested
in investigating new methods of observation, as well as innovative designs for
pavements to be used in the future.
