The TRB Superpave Committee has released its final report summarizing the committee’s work since 1999, when it was formed to advise the American Association of State Highway and Transportation Officials and the Federal Highway Administration on a research plan that would further the development and implementation of the Superpave system for selecting materials and designing asphalt mixtures to meet climate and traffic conditions of specific roadway paving projects. The report describes the current status of Superpave implementation, reviews the research goals and outcomes, briefly describes the programs and practices that helped achieve nationwide implementation of a technology in just a decade, and outlines work that remains to be done to maximize the value of the investment in Superpave.
