Analysis of Asphalt Pavement Materials and Systems: Emerging Methods contains 13 papers presented at the symposium on Mechanics of Flexible Pavements at the 15th U.S. National Congress of Theoretical and Applied Mechanics, held in Boulder, Colorado, June 25-30, 2006. This Geotechnical Special Publication covers a variety of important and timely topics in the characterization, modeling, and simulation of the behavior of asphalt pavement systems. Topics discussed include modeling, numerical implementation and simulation, and experimental characterization. Engineers involved in mix design, pavement design and analysis, and pavement performance assessments will benefit from this report.
