This report documents a historical review of the development of asphalt binder performance specifications, experimental design, test pavement construction and performance, statistical methodology to rank and identify the strongest candidates, and all pertinent laboratory characterization of binders and mixtures that supplemented the recommendations. The research also provided a detailed case study of pavement evaluation using falling weight deflectometer and objective means to evaluate two emerging technologies; the asphalt mixture performance tester and the Mechanistic-Empirical Pavement Design Guide.
