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.
