RESEARCH
PROBLEM STATEMENT:
Dedicated
pavement facilities for deicing operations have been constructed
at several airports in North America. Some of those facilities
have experienced premature pavement distress, but the extent of
this issue is not known. The distress appears to occur within
two to three years. The deteriorated facilities have not been
studied to determine if there is a detrimental interaction of
the aircraft de-icing chemicals and/or the concrete's constituent
materials, if the construction techniques affected the deterioration,
and if environmental conditions influenced the deterioration.
As the industry moves to build more dedicated de-icing facilities,
the nature of the distress must be determined. This research is
intended to determine the nature and extent of the deterioration
at dedicated facilities and provide an overview of any challenges
and potential solutions to specifiers, designers, contractors
and owners.
For
this study, dedicated de-icing facilities are defined as those
facilities that are specifically for the purpose of aircraft de-icing.
Typically, these facilities include a collection and treatment
mechanism for the collection of run-off and are not integral to
enplanement facilities. The frequency of use and the concentration
of de-icing chemicals are likely to be higher at dedicated facilities
than on an apron de-icing operations occur at numerous locations.
OBJECTIVES:
The
overall objectives of this research project are:
- Determine
the extent of Portland Cement Concrete pavement distresses with
a quantitative review of dedicated de-icing facilities in North
America through a site visit and meeting with airport operations
personnel. Create a database of these facilities, intended to
answer the following questions as a minimum:
- How
many of these facilities are deteriorated?
-
What types and extent of distress exists (if any)?
- What
was the relative age of the concrete when the deterioration
appeared?
- What
types of joint sealants were used?
- What
specifications or modifications to standards were used for
the projects (P-501, etc.)?
- What
de-icing chemicals are used at the facility?
- What
relative quantity of de-icing chemicals is used?
- Are
there other chemicals used on the facility?
The
proposal should identify other variables that the research team
deems relevant. (Note: The IPRF will provided the research
team that is awarded the contract a list of at least ten dedicated
de-icing facilities to be used for this database.)
- Perform
a forensic analysis to determine the extent and nature of distressed
concrete observed at dedicated airplane de-icing facilities.
The forensic study should include, but not be limited to petrographic
studies and visual distress surveys. This will involve field
sampling, testing, and data analysis. The proposal should outline
the forensic analysis methods that will be used and how many
tests the research team deems feasible. The selection of specific
sites for forensic analysis will be coordinated with the technical
panel after information from the database is complete. A minimum
of four airports must be the subject of a forensic analysis,
and at least one of those four is a facility without early distress.
- Determine
the cause of concrete distress at the facilities where forensic
analysis is performed and then compare and contrast these results
to identify similarities and/or differences in their mechanisms
of deterioration. Identify if a specific mechanism of concrete
deterioration is caused or exacerbated by airplane de-icing
chemicals.
- Provide
an overview of the challenges, potential solutions and information,
including future research, needed to prevent deterioration that
may be the result of the design, specification and/or construction
of de-icing facilities.
REVIEW
MEETINGS:
There
will be several interim milestones:
Start-up
- At the onset of the project the research team will review the
literature search performed under IPRF Project 01-G-002-03-9 "Potential
for Acceleration of ASR In the Presence of Pavement Deicing Chemicals."
The researcher will use this review to identify any concrete deterioration
information germane to this study.
20%
Review - The researcher will submit an interim report of the
findings used to populate the database and will define the extent
of the de-icing facility pavement deterioration / early distress.
The researcher will submit a final work plan that fully describes
the forensic analysis techniques and process. The research team
will meet with the Technical Panel for an on-board review at the
offices of the research team for the 20% review meeting.
75%
Review - The researcher will present the results of their
forensic analysis to the technical panel. The review will be an
on-board meeting with the Technical Panel.
90%
Review - The
researcher will submit their draft final report to the technical
panel. The technical panel will review the report and return written
comments to the researcher. A telephone conference call will be
conducted after the researcher reviews the panels' comments to
clarify any comments, suggestions, etc.
PRODUCTS:
There
are two deliverables:
- A
final research report documenting the database and the review
of de-icing facilities, the results of the forensic analysis
(field and lab test procedures), identification of the deterioration
mechanism, and finally, a recommended roadmap to prevent and
mitigate the distress(s) observed. The report will be submitted
as two original documents and an additional one on electronic
media.
-
An Executive Report briefly describing the research findings
and recommendations. The report will be submitted as two original
documents and one on electronic media.
TASK
ORGANIZATION:
The
following are considered the minimum tasks that are necessary
to complete the study. The proposal may include an increase in
the number of tasks but the number of review meetings specified
above must be retained.
Task
1 - Research Plan and Review of Literature: The research team
will review the literature search performed under IPRF Project
01-G-002-03-9 "Potential for Acceleration of ASR In the Presence
of Pavement Deicing Chemicals." The findings of this review will
be used in the research plan. The research plan should outline
in detail the work to be accomplished, addressing the objectives
described above, and any additional work proposed.
Task
2 - Devise and Populate Database of De-Icing Facilities: This
task includes the collection of general performance and other
information the researcher deems important to determine the extent
of premature pavement deterioration problems on dedicated de-icing
facilities. At least ten airports are to be visited to collect
information for this task. (One must be to an airport in Canada.)
Task
3 - Interim Report and Data Review: At the end of Task 2 a
meeting with the technical panel will be conducted. The researcher
will submit an interim report of the findings of the extent of
the de-icing facility pavement deterioration problem. The researcher
will also submit their final work plan for the forensic study.

SPECIAL
CONSIDERATIONS:
As
part of the selection process, the Technical Panel will evaluate
each proposal and subsequently the proposals will be rank ordered.
The panel may ask the team that developed the proposal to participate
in a telephone interview if a proposal is ranked as either the
first and/or second rank. The Principal Investigator, and one
other person representing the team, may be asked to participate
on the interview and discuss the project details, goals, and objectives.
The interview will occur within a 45-day window subsequent to
the proposal submittal deadline. The IPRF will attempt to provide
as much lead time as possible to the Principal Investigator as
to the date of the interview; however, the process may not allow
more than a 12-hour notice.
