NATIONAL COOPERATIVE HIGHWAY RESEARCH PROGRAM Systematic, well-designed, and implementable research is the most effective way to solve many problems facing state departments of transportation (DOTs) administrators and engineers. Often, highway problems are of local or regional interest and can best be studied by state DOTs individually or in cooperation with their state universities and others. However, the accelerating growth of highway transporta- tion results in increasingly complex problems of wide interest to high- way authorities. These problems are best studied through a coordinated program of cooperative research. Recognizing this need, the leadership of the American Association of State Highway and Transportation Officials (AASHTO) in 1962 ini- tiated an objective national highway research program using modern scientific techniques—the National Cooperative Highway Research Program (NCHRP). NCHRP is supported on a continuing basis by funds from participating member states of AASHTO and receives the full cooperation and support of the Federal Highway Administration (FHWA), United States Department of Transportation, under Agree- ment No. 693JJ31950003. The Transportation Research Board (TRB) of the National Academies of Sciences, Engineering, and Medicine was requested by AASHTO to administer the research program because of TRB’s recognized objectivity and understanding of modern research practices. TRB is uniquely suited for this purpose for many reasons: TRB maintains an extensive com- mittee structure from which authorities on any highway transportation subject may be drawn; TRB possesses avenues of communications and cooperation with federal, state, and local governmental agencies, univer- sities, and industry; TRB’s relationship to the National Academies is an insurance of objectivity; and TRB maintains a full-time staff of special- ists in highway transportation matters to bring the findings of research directly to those in a position to use them. The program is developed on the basis of research needs iden- tified by chief administrators and other staff of the highway and transportation departments, by committees of AASHTO, and by the FHWA. Topics of the highest merit are selected by the AASHTO Special Committee on Research and Innovation (R&I), and each year R&I’s recommendations are proposed to the AASHTO Board of Direc- tors and the National Academies. Research projects to address these topics are defined by NCHRP, and qualified research agencies are selected from submitted proposals. Administration and surveillance of research contracts are the responsibilities of the National Academies and TRB. The needs for highway research are many, and NCHRP can make significant contributions to solving highway transportation problems of mutual concern to many responsible groups. The program, however, is intended to complement, rather than to substitute for or duplicate, other highway research programs.

NCHRP Research Report 1007 presents representative performance prediction curves for bonded concrete overlays on asphalt (BCOAs). The representative performance prediction curves are based on comprehensive laboratory and field investigations for determining best practices for scoping, design, material selection, construction, maintenance, repair, and rehabilitation of BCOA pavements. This report will be of immediate interest to construction and maintenance engineers. BCOA pavements are a fast-growing pavement preservation and rehabilitation treatment in the United States. They have demonstrated their effectiveness in 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-in. thick concrete overlay, with or without fibers, with panel sizes ranging from 4 to 12 ft. Major advancements have been made recently in design methods for BCOAs. However, there was a need for information on key topics such as optimal BCOA mix design propor- tioning, construction practices, maintenance, repair, and rehabilitation, as well as a com- prehensive 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 mainte- nance and repair activities need further study and definition. Some highway agencies are reluctant to use BCOAs because of a lack of experience and information. Thus, research was needed to determine expected BCOA performance. Other aspects of BCOAs such as construction practices (“do’s and don’ts”) and maintenance, repair, and rehabilitation requirements and procedures also need attention. Under NCHRP Project 01-61, “Evaluation of Bonded Concrete Overlays on Asphalt Pavements,” Nichols Consulting Engineers was asked to (1) investigate factors that may impact BCOA performance including design procedures, specifications, mix design pro- portioning, 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.

The use of thin bonded concrete overlays on asphalt (BCOAs) as a rehabilitation treatment first gained momentum in the 1990s. Since the first documented thin BCOA application in the United States, in Louisville, Kentucky, in 1991, BCOAs have seen a dramatic increase in popularity.

The TRB National Cooperative Highway Research Program's NCHRP Research Report 1007: Evaluation of Bonded Concrete Overlays on Asphalt Pavements documents BCOA practices through a literature review and agency survey; documents performance through site investigations that assessed in-service design, construction, performance, preservation, and rehabilitation; and compares the results of current design methods with actual performance.

Supplemental to the report is NCHRP Web-Only Document 329: Bonded Concrete Overlays on Asphalt Pavements: Resources for Evaluation, which provides Appendices A through G of the contractor’s final report.
