Superior Performing Asphalt Pavement: Superpave: Performance by Design

This report briefly recounts the actions and outcomes that were the contributions of the Transportation Research Board (TRB) Superpave Committee to a nationwide Superpave implementation effort. Chapter 1 discusses the results of a survey conducted by the TRB Superpave Committee to determine current use of Superpave. The survey found that 50 of 52 responding transportation agencies report general use of the Superpave asphalt binder standard specification; the other two agencies are initiating plans to do so. Of the 52 responding agencies, 36 report general application of the Superpave mixture design standard, with 12 others reporting use on high-volume highways. Three other agencies have plans to initiate use. Chapter 2 relates the goals of the 2005 Plan to the current status of efforts to meet them. The 2005 Plan was developed by the TRB Superpave Committee to guide Superpave deployment activities. A brief sketch of the committee's deployment activities is included in chapter 3. Although it is apparent that implementation efforts have succeeded and that Superpave has in fact been mainstreamed, members of the TRB Superpave Committee share concerns in several areas of application. Chapter 4 discusses the committee's recommendations regarding opportunities to improve, extend, or enhance the Superpave system and the performance of hot-mix asphalt.
