Airfield Asphalt Pavement
Technology Program (AAPTP)
Asphalt pavements represent a considerable investment in the infrastructure of airfields. It is estimated that 80-85% of the airfield pavements are surfaced with asphalt. The majority of these pavements are the smaller, lighter trafficked airfields that have limited funding for repairs and pavement maintenance activities. These airfields are subjected to a wide range of climatic conditions that often result in thermal cracking, large block cracking and surface deterioration that are not load related. Several products and procedures are being promoted as corrective or deterrent measures to these types of distresses. A comprehensive study is needed to provide guidance to airfield engineers and managers to address cost effective prevention and mitigation of these types of pavement distresses.
The objective of this study is to provide comprehensive technical guidance on the causes and measures required to correct and/or prevent non-load related distress on asphalt airfield pavements. This study is divided into two phases. Phase I (this request for proposals) will consist of a literature review of the extent of the problem, development of a comprehensive list of products and procedures presently used to address the problems, and a detailed work plan to be conducted in Phase II. Phase II of the project shall consist of conducting a work plan that was developed and approved in Phase I. Phase II work plan is to address the shortfalls and gap in knowledge on the prioritized non load related distresses and conditions and/or validate a systematic approach to select appropriate corrective measures and products for repair of pavement exhibiting non-load related distress. Phase II may be awarded without further competition pending performance and satisfactory completion of Phase I of this project.
The literature review and final products from Phase I shall consider but shall not be limited to the following:
Specific conditions for airfield pavements should consider the following:
The products for Phase I of this project shall consistent of: (1) comprehensive literature review on non-load related distress of asphalt airfield pavements; (2) review and listing of products and procedures for repair and/or prevention of non-load related distress; and (3) a detailed work plan to investigate and address the most critical issues associated with non-load related distress. These products shall be developed by addressing the following tasks:
Task 1 -- Review and summarize existing literature on non-load related distress and corrective measures on asphalt airfield pavements.
Task 2 -- Develop a matrix of factors contributing to non-load related distress and assess the geographical distribution of potential airfields exhibiting specific non-load related distress.
Task 3 -- Provide a preliminary report outlining findings to date and future course of actions that are being considered. The report is expected to be presented to the technical panel at a mutually agreed upon location 3-4 months after award. The purpose of this meeting is for the technical panel to provide comments and direction for the completion of Phase I and understand direction of possible proposals for Phase II.
Task 4 -- Identify potential laboratory tests that may be used to assess key properties of the HMA and specific site conditions that may be used to predict non-load related distress in airfield pavements.
Task 5 -- Develop and submit draft report containing work completed and the detailed work plan for Phase II of the project. Comments will be provided by the technical panel within 30 days of receiving the preliminary report documents.
Task 6 -- Develop Phase I final report. This report shall include revised literature and product review and a comprehensive research plan for Phase II. The research plan shall be similar in format and content as the request for proposal. The plan shall include a technical approach, cost and manpower proposal to complete Phase II within 24 months and within the $330,000 funding limitation. This plan and the performance of the contractor in Phase I shall be used by the technical panel for recommendation for award without further competition of Phase II of the project.
All written documentation will be prepared using Microsoft Word unless otherwise stated. All reports will be the property of the AAPTP and Auburn University and will be supplied in a format that complies with the FAA's Section 508 requirements for electronic documents.
Quarterly progress reports (2 hard copies and an electronic copy in Microsoft Word format) are required from the research agency and are to be prepared on the basis of calendar quarters. The research agency will mail the report directly to the AAPTP and will e-mail each of the members of the technical review panel a copy of the progress report. Each report will include a cover letter and the following:
The formats for the Interim and Final reports are provided under "Research Process."
Funds Available: $150,000
Contract Time:12 months (includes 1 month for AAPTP to review and for the contractor to revise the final report.)
