Potential for Acceleration of ASR In the Presence of Pavement De-icing Chemicals

Requests Closed


There are numerous research reports supporting the theory that alkaline halide salts have the potential to aggravate (i.e., increase) the expansion rate and, thus, the resultant damage to concrete with alkali silica reaction (ASR). While halide-bearing salts are generally avoided for airport use because of the corrosive effect on metals, no significant investigation has been done to determine if other alkaline deicers have a similar effect on ASR. Such alkaline deicers are commonly used on airfield pavements, including airfield pavements affected by ASR. A laboratory study is required to either confirm or refute the hypothesis that ASR can be accelerated by the use of deicing chemicals.


The research program will be in the form of a two step solution. 1. Identify if there is a problem. This effort will be a laboratory exercise. 2. If there is a problem, what is the recommended path for determining the probable mitigation methods? The actual work effort to accomplish the second part will be described as a program (a roadmap) for a future research project. The roadmap to finding mitigation measures however, must be definitive based upon the results of this research effort.

A literature search will be accomplished. The purpose is to identify the various chemicals that are currently marketed as well as chemicals being considered for use in the airfield pavement environment. The literature search will also determine if there are any recent research reports that identify select chemicals as accelerants of ASR.

The laboratory study will include the testing of concretes that are made with aggregates known to be reactive. The materials used should represent combinations of materials usually used in various regions of the United States.

The research plan for this project will be designed to clearly show whether or not alkaline deicers have significant potential to increase expansion and damage of ASR-affected airfield pavements


The final product will be an Innovative Pavement Research Foundation (IPRF) report that provides the results of the laboratory investigation and the literature search. The recommended path for determining probable mitigation methods for the problem identified by the research will be included in the final report. At the conclusion of the research there should be a document(s) that the engineer or constructor can read and through reading gain an understanding of the problem and the potential for mitigating the problem.

The final report will be provided to the IPRF in the form of two originals, in a camera ready format, including any artwork, graphics or photos. An electronic version of the final report in a format compatible with off-the-shelf desktop computer publication software will also be provided. The investigator will not be responsible for the reproduction and printing of the final document(s) but will assist with minor editing requirements generated by the printing and reproduction process.

The investigator is expected to develop sub-tasks that when completed will result in completion of the project within the time and budget available. It is not necessary that the proposal reflect the exact budget or the planned time. However, any deviation from the designated resources must be justified and clearly explained in the proposal. The following are the minimum tasks that are considered necessary to complete the project.

Task 1 - Literature Review and Information Gathering.

A. Review existing literature. Provide a summary of any previous research or reported problems with deicing chemicals used in the airport environment.

B. Using the list of commercial airports provided by the IPRF, develop a list of the deicing chemicals used on airfield pavements by those airports.

IMPORTANT: A written survey will not be accomplished to determine what deicing chemicals are used for airfield pavements. A survey is defined as the random distribution of a standard list of questions that seek trends or forecasting information. The use of such surveys must receive approval through the IPRF from the Office of Management and Budget (OMB). That process requires a minimum of 90 days from the date of application for the survey approval. The 90 day approval period is not included in the time designated as the performance period. The investigator is encouraged to use a means other than "survey" to identify airports that use deicing chemicals and the chemicals are.

Task 2 - Document a Research Plan. Develop a plan for doing the research. The anticipated techniques and tests to be employed in the laboratory will be straightforward. It is preferred that the tests specified would have been used successfully in other published research to investigate the effects on ASR by chemical compounds. It is to be expected that some known rapidly reactive aggregate species would need to be included in this program. Selected specimens should include petrographic evaluation to investigate and document the nature of deteriorations and expansions observed as a result of the testing regimes. The submittal of the research plan to the IPRF Technical Panel is designated as the 20% review point of the research.

A 20% on-board review will be accomplished. The investigator will not proceed to Task 3 without the written approval of the IPRF. An on-board review must be scheduled at least 30 days prior to the actual meeting. Documents that are prepared for technical panel review must be provided at least 30 days prior to the meeting. The location of the meeting will be coordinated with the IPRF. The investigator is responsible for documenting the comments of IPRF Technical Panel members and the disposition of each comment.

Task 3 -Collect Samples. Collect the chemicals and materials identified in the test plan.

Task 4 -Perform Laboratory Studies. Accomplish the laboratory studies according to the research plan.

As a part of the proposal, the researcher will designate the approximate time after the laboratory study begins to report initial findings. The summary of initial findings is defined as the 60% review point of the research. The initial findings report will include the summary of the literature search, the list of deicing chemicals used usage at airports, observations of the initial laboratory testing and the lessons learned from the studies through the date of the report. The report should be prepared and submitted at a time in the laboratory process that corrections to the test plan or modifications of test protocols would be deemed appropriate.

A 60% on-board review will be accomplished. The review will be a meeting between the investigator and the IPRF Technical Panel. The initial findings report will be provided to the technical panel at least 30 days prior to the meeting. The investigator is expected to present to the technical panel discussion items that will result in policy decisions for critical elements of the final report. Additional research may be needed to respond to questions that are developed as a result of the on-board review. The location of the meeting will be coordinated with the IPRF. The investigator is responsible for documenting the comments of IPRF technical panel members and the disposition of each comment.

Task 5 - Advanced Final Report. When the laboratory study is completed, make corrections using the 60% review, additional data gathered as a result of the 60% review and the completion of the laboratory testing. Include in the report all artwork, graphical presentations, format, etc. The document shall be in a form that for all intent is complete with the exception of final comments made by the Technical Panel. The submittal of the advanced final report is designated as the 90% review point of the research project.

A 90% on-board review will be accomplished. The advanced final report will be submitted to the IPRF Technical Panel for review. The Technical Panel will have 30-days to review and comment on the report. The report will include a summary of the results of testing and recommendations for the research plan that should be followed for mitigation of problems that are discovered as a result of the research. The investigator is responsible for documenting the comments of IPRF Technical Panel members and the disposition of each comment.

Task 6 - Final Report. Make corrections to the 90% document and submit the final documents to the IPRF. Assist the IPRF with publication related editing.
