FOREWORD

This final report provides the comprehensive findings from two Transportation Pooled Fund (TPF) research projects, TPF-5(019): Full-Scale Accelerated Performance Testing for Superpave and Structural Validation and SPR-2(174): Accelerated Pavement Testing of Crumb Rubber Modified Asphalt Pavements. The research identified candidate purchase specification tests for asphalt binder that better discriminate expected fatigue cracking and rutting performance than current SUperior PERforming Asphalt PAVEment (Superpave®) tests. Full-scale accelerated pavement testing and laboratory characterization tests on mixtures and binders provided the basis for the recommendations.

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.(1)

This document will be of interest to highway personnel involved with Superpave®, materials selection, performance specifications, and pavement design and evaluation.
