PROFILES IN PRESERVATION

Crack Sealants: Know When to Say When
Editor's Note: This is the fifth 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 Andrew Fried, whose work at North
Carolina State University involves performance of crack sealants.
WHAT GOT YOU INTERESTED IN
PAVEMENT PRESERVATION?
After taking a class on construction materials and beginning lab work under my current advisor, Dr. Cassie Castorena, I quickly
became interested in different pavement
preservation techniques. Navigating the
lab as an undergraduate to assist both
graduate and Ph.D. students with their
research further exposed me to the diverse
project types. It was throughout my time

working with these diverse projects that
lead me to pursue a graduate program
in which I could continue working with
pavement preservation.
HOW IS YOUR RESEARCH RELATED
TO PAVEMENT PRESERVATION?
Currently, my research focuses on crack
sealants. Specifically, my project considers the use of crack sealant and the maximum amount of sealant that can be applied

before negatively impacting skid resistance
to reduce wet weather accidents  and
enhance safety.
Because crack sealant is effective for
preventing moisture intrusion into cracks
and slowing the deterioration of pavement, due to budgetary constraints, it's
often overused in place of more costly
rehabilitation treatments.
The goal of my research is to examine different routes in North Carolina
and quantify the impact that different
patterns of crack sealant have on skid
resistance, to ensure that this preservation
method is not reducing the skid resistance
to a point where the roads drop below the
minimum limit required to ensure safety.
