Author Description

Selected papers from the Pavements and Materials: Characterization and Modeling Symposium, part of the EMI 2010 conference, held in Los Angeles, California, August 8-11, 2010. Sponsored by the Mechanics of Pavements Committee of the Engineering Mechanics Institute of ASCE. This Trends in Engineering Mechanics Special Publication contains 18 peer-reviewed technical papers on the proper characterization and modeling of pavements and roadway materials. Such efforts are often extremely challenging because of significant material heterogeneity at different length scales and the complexity and variability of damage and distress at a minute scale. Therefore, testing and modeling at multiple length scales can be ideal tools to gain accurate insight into the mechanisms and factors that affect the performance of mixture and structure scales. This special publication addresses the current advances and ongoing efforts in multiple length scale research in the area of pavement materials, mixtures, and structures Topics include: characterization and modeling at asphalt mixture component scale, modeling at asphalt concrete laboratory specimen scale, and characterization and modeling at large or pavement scale. Pavement materials and design engineers and researchers will benefit from the multiple length scale characterization and modeling techniques and methods presented in this publication.
