BACKGROUND
 
Bonded concrete overlays on asphalt (BCOA) pavements are a fast-growing pavement preservation and rehabilitation treatment in the United States. They have demonstrated their effectiveness as solutions for correcting areas with excessive rutting and shoving caused by slow, heavy loads, such as at intersections, as well as for a longer term overlay option on regular mainline pavements. Most BCOA projects consist of a 3- to 7-inch thick concrete overlay, with or without fibers, with panel sizes ranging from 4 to 12 feet.
 
Major advancements have been made recently in design methods for BCOA. However, there is still a need for information on key topics such as optimal BCOA mix design proportioning, construction practices, maintenance, repair, and rehabilitation, as well as a comprehensive review of overall performance. Current assumptions about anticipated design lives of BCOAs are derived from localized studies. Variables impacting design life include the previous condition of the existing pavement structure, the time dependent degree of bond between layers, overlay thickness, panel size, construction practices, environment, and traffic. Typical BCOA design lives are uncertain, and the timing and types of maintenance and repair activities need further study and definition.
 
Some highway agencies are reluctant to use BCOA because of a lack of experience and information. Thus, research is needed to determine expected BCOA performance. Other aspects of BCOA such as construction practices ("do’s and don’ts") and maintenance, repair, and rehabilitation requirements and procedures also need attention.
 
OBJECTIVES
 
The objectives of this research are to: (1) investigate factors that may impact BCOA performance, including, but not limited to, design procedures, specifications, mix design proportioning, construction practices, and maintenance and repair techniques; (2) document in-service BCOA performance through a literature review and survey; (3) conduct field surveys of selected BCOA projects; (4) develop representative performance prediction curves suitable for use in BCOA design selection based on the documented performance of a range of BCOA projects; and (5) compare actual versus predicted BCOA performance using current design procedures.
 
RESEARCH PLAN
 
Proposers are asked to provide a detailed research plan for accomplishing the project objectives and for producing the deliverables required by each phase of the project. Proposers are expected to describe research plans that can realistically be accomplished within the constraints of available funds and contract time. Proposals must present the proposers' current thinking in sufficient detail to demonstrate their understanding of the issues and the soundness of their approach to meeting the objectives. The work proposed for each phase must be divided into tasks and proposers must describe the work proposed in each task in detail.
 
Deliverables shall include, at a minimum:
 
PHASE I
 
1. A literature review and a survey of state, provincial, and local highway agencies to identify current and past BCOA projects and determine, insofar as possible, their performance (including premature failures), design procedures, specifications, mix design proportioning, construction practices, and overlay maintenance and repair techniques.
 
2. An updated work plan to (a) measure the performance of selected BCOA projects, (b) develop representative performance prediction curves suitable for use in design selection, and (c) conduct comparisons of actual versus predicted BCOA performance using current design procedures.
 
The work plan shall identify specific field projects for performance measurement, provide a detailed experimental design, including methods and equipment, and describe a proposed methodology for developing performance curves.
 
3. An interim report that presents (a) findings of the literature review and survey and (b) the updated work plan.
 
Note: Phase I is limited to 3 months. The contractor will meet with NCHRP within 1 month of submission of the interim report to obtain approval to proceed with Phase II.
 
PHASE II
 
1. Execution of the work plan approved in Phase I.
 
2. A technical memorandum presenting a comprehensive review of measured BCOA field performance.
 
Note: The contractor will meet with NCHRP within a month of submission of the technical memorandum to discuss the findings and obtain approval to develop the performance curves.
 
3. A technical memorandum presenting a detailed discussion of the development of BCOA performance prediction curves from the field measurements, a summary of observed maintenance and repair techniques, and a comparison of actual versus predicted BCOA performance using current design procedures.
 
4. A final report that documents results, summarizes findings, draws conclusions, and proposes best practices for scoping, design, material selection, construction, maintenance, repair, and rehabilitation of BCOA pavements. An appendix to the report shall include electronic files of all test data and results collected and measured in the research.
 
SPECIAL NOTES

A. The proposal, including appendices, shall not exceed 30 single-spaced pages and the Research Plan, Item 4 of the proposal, shall not exceed 20 single-spaced pages, in 12-point font or larger.

B. For budgeting purposes, proposers should plan for 2 in-person meetings with NCHRP in  Washington, DC or Irvine, CA.

C. Proposals should include a task-by-task breakdown of labor hours for each staff member as shown in Figure 4 in the brochure, "Information and Instructions for Preparing Proposals" (http://onlinepubs.trb.org/onlinepubs/crp/docs/ProposalPrep.pdf). Proposals also should include a breakdown of all costs (e.g., wages, indirect costs, travel, materials, and total) for each task using Figures 5 and 6 in the brochure. Please note that TRB Cooperative Research Program subawards (selected proposers are considered subawards to the National Academy of Sciences, the parent organization of TRB) must comply with 2 CFR 200 – Uniform Administrative Requirements, Cost Principles, and Audit Requirements for Federal Awards. These requirements include a provision that proposers without a "federally" Negotiated Indirect Costs Rate Agreement (NICRA) shall be subject to a maximum allowable indirect rate of 10% of Modified Total Direct Costs. Modified Total Direct Costs include all salaries and wages, applicable fringe benefits, materials and supplies, services, travel, and up to the first $25,000 of each lower-tier subaward and subcontract. Modified Total Direct Costs exclude equipment, capital expenditures, charges for patient care, rental costs, tuition remission, scholarships and fellowships, participant support costs and the portion of each lower-tier subaward and subcontract in excess of $25,000.
 
D. The NCHRP is a practical, applied research program that produces implementable products addressing problems faced by transportation practitioners and managers. The benefits of NCHRP research are realized only when the results are implemented in state DOTs and other agencies. Implementation of the research product must be considered throughout the process, from problem statement development to research contract and beyond completion of the research. Item 4(c), "Anticipated Research Results," must include the following: (a) the "product" expected from the research, (b) the audience or "market" for this product, (c) a realistic assessment of impediments to successful implementation, and (d) the institutions and individuals who might take leadership in deploying the research product. The project panel will develop and maintain an implementation plan throughout the life of the project. The research team will be expected to provide input to an implementation team consisting of panel members, AASHTO committee members, the NCHRP Implementation Coordinator, and others in order to meet the goals of NCHRP Active Implementation: Moving Research into Practice, available at http://onlinepubs.trb.org/onlinepubs/nchrp/docs/NCHRP_ActiveImplementation.pdf.
