HOW FP 2 WORKS FOR YOU
Boot Camp Boosts Preservation Interest
Editor's Note: This is the third of a continuing series of profiles of civil engineering
students who are undertaking pavement preservation as a course of study. These
students bring a different perspective of why a young civil engineer would pursue
preservation study, and this issue focuses on graduate student Clint Van Winkle,
whose work at Auburn University involves the FP2-funded Pavement Preservation
Experiment at NCAT, which is also continuing at MnROAD north of Minneapolis.
WHAT GOT YOU INTERESTED IN
I first became interested in pavement
preservation as a master's student at the
University of Iowa. My advisor at the time,
Dr. Hosin "David" Lee, assisted in teaching a two-week intensive advanced civil
infrastructure management boot camp that
was part of the Annual Inter-University
Symposium on Infrastructure Management,
also known as AISIM.
Professor Lee thought it would be a
good opportunity to present some of the
research I had been working on and learn
more about pavements. This was my first
exposure to the concept of managing pavements through preservation.
There, I first learned how shrinking
budgets and poor management were contributing to the decline of an already poor
infrastructure. We also learned about how a
pavement preservation strategy was a more
efficient use of materials and labor, which got
me all fired up about pavement preservation!
After the boot camp, I went back to Iowa
to finish up my research on thin overlays,
when at a conference I met Dr. Randy West,
the director of the National Center for
Asphalt Technology (NCAT).
When Randy asked me if I had ever
considered getting my Ph.D. at Auburn
University, I must admit I didn't even know
what state Auburn was in! After a Google
search I quickly found out where it was and
what a great school it was for pavements.
Within a week of graduating from Iowa,
in the summer of 2014, I had everything
I owned in my truck and was on my way
down to Alabama. At Auburn, I began
my studies where I was amazed by the
amount of learning that was available specifically to pavements. After a semester
working with Dr. West, I began working
directly with Dr. Mary Robbins solely on
HOW IS YOUR RESEARCH RELATED TO
Currently, Mary and I are examining how
pavement preservation technologies protect
the subgrade. The scope of our work focuses
primarily on the information gathered from
the Lee Road 159 Pavement Preservation
Experiment, in which FP2 Inc. is a major
This project includes 25 100-ft. test sections with a variety of pavement preservation technologies applied individually and in
combination. This experiment is located on
the access road to a quarry and an asphalt
plant, which means that the traffic frequency and magnitude is well documented,
and the inbound and outbound lanes are
exposed to different amounts of loading.
There is a variety of testing that has been
completed on Lee Road 159. Each month,
falling weight deflectometer (FWD) testing, crack mapping, and subgrade moisture testing is undertaken and goes along
with weekly testing of rutting, texture
We are specifically investigating the relationship between precipitation, cracking,
subgrade moisture, and FWD-measured
deflections. By observing these variables for
each of the pavement preservations we are
hoping to quantify the benefit of these techniques to preserve the pavement structure.
HOW HAS YOUR PERSPECTIVE
CHANGED ABOUT OUR ROAD INFRASTRUCTURE SINCE BEGINNING
Back when I first started my master's program at the University of Iowa, I just didn't
know how bad the situation was. I would
read about how the infrastructure in the
United States received a D "grade," but I
felt the situation was being blown out of
proportion. I mean, I could use the roads,
so I thought everything was fine.
What I didn't understand was that locations (mostly not in Iowa) have severe congestion problems that are made worse by
lengthy construction times, and those little
bumps in the roads were causing more
problems than just a mild discomfort.
The good news is that pavement preservation can prolong the life of the pavement,
thus minimizing the frequency of long construction delays associated with rehabilitation and keep the pavement condition at a
higher quality for a longer amount of time,
which causes less damage to our vehicles.
DO YOU HAVE PLANS TO CONTINUE
IN THE FIELD OF PAVEMENT PRESERVATION UPON GRADUATION?
I am most definitely looking to continue
in the field of pavement preservation after
graduation! Whether I go into academia, an
agency position, or the private sector, I can't
imagine that it will not include pavement
preservation in some manner.
Currently, I am hoping to complete the
Ph.D. program at Auburn University in the
summer of 2017. I have extensive knowledge
in pavement preservation, condition analysis, and asset management, so I am also
eager to begin my career with an employer
that I can grow with as I achieve their goals.
