Airport Business - 25

"We didn't do any airfield projects because we had invested
so much in getting the ground ready and airfield in a position
in which we could have a new terminal and previous airport
administration set us up well in that regard. They got the airfield
in good order knowing that we were going to be committed
to maintaining the new terminal building," explained David
Schaumburg, SGF's assistant director of aviation.
Come 2017, though, the pavement began to show its age
with noticeable cracks forming in the taxiway due to alkalisilica reaction (ASR).
"My field maintenance folks and ops folks were making
comments about that area of the airfield and how they were
seeing a lot of cracking on the surface of taxiway uniform
and really, it was breaking up a significant amount, showing a
rapid deterioration likely due to ASR. A lot of swelling," said
Schaumburg.
Eventually, a large crack formed running lengthwise
on Taxiway U, encompassing eight to 10 panels along
the taxiway's edge. The cracked portion of the
taxiway was adjacent to about 450,000
square feet of cargo ramp space. Both
UPS and FedEx utilize SGF.
Yet, with airport funds
tied up in terminal

bond debt at the time, a large-scale replacement of the ruptured
concrete was not feasible.
Working with engineering consulting firm Crawford,
Murphy & Tilly, the airport was able to come up with some
temporary solutions.
"They gave us some recommendations. We ended up doing
a mill on that concrete. We did a four-inch mill and went back
with two, two-inch lifts of hot mix asphalt just to buy us some
time while we could do some programming," said Schaumburg.
The following year, though, additional cracking began
forming out outside of that asphalt patch and SGF ended up
having to do another mill and fill to buy more time.
"It was certainly showing rapid deterioration, something that
we were very nervous about, especially with all of our cargo
operations going through that area and so, we had to get on it
with doing design and knowing we had a big project that it was
going to need to get programmed in," Schaumburg recounts.
Able to free up funds to put towards their much-needed
pavement repairs, the $7.29 million project began last year with
Crawford, Murphy & Tilly coming in to perform a Pavement
Management Plan (PMP) update - SGF's first since the early
2000s.
"There've been a lot of changes between 2000 and today.
A lot of pavements that didn't exist 20 years ago," said Brian
Hutsell, project manager, Crawford, Murphy & Tilly. "The
PMP consisted of a visual inspection of the airfield pavements.
We went there and walked all of the airfield pavements over
the course of about two and a half weeks."
The roadmap of pavement work needed indicated Taxiway
U as needing the most attention and Hutsell said the team fast
tracked aspects of the project because of its rapidly deteriorating
condition.
"We did some surveys on Taxiway Uniform ahead of time
to justify that project to the FAA to get funding a little earlier
than the rest of these projects," Hutsell said.
Ty Sander, vice president and aviation group manager,
Crawford, Murphy & Tilly, said the project involved
