The proposed supplement request is to support the following activities: 1) Dr. Wangs stay at the University of Cambridge for three months; 2) One graduate students stay at the Delft University of Technology (DUT) for six months; and 3) Dr. Wangs short visit of Delft University of Technology for student advising and collaboration with Dr. Tom Scarpas. This arrangement is considered more beneficial to the current project. The long-term objective of these activities is to establish a strong triangle among three research groups, the Virginia Tech group, the Cambridge Group and the Delft group with focus on microstructure, micromechanics and computational simulation of asphalt concrete and other stone-based infrastructure materials. The specific technical objectives include a) joint development of an aggregate-binder interface model by Wang and Cebon; b) development of representation techniques for 3D complex shapes for efficient computational simulation by the graduate student co-advised by Wang and Scarpas. These technical objectives are directly related to the PFI (Partnership for Innovation) project (EEC-0619969, Expiration Date 09/30/2008, Development and Implementation of Digital Specimen and Digital Tester Technique for Infrastructure Materials) and present the potential to extend the partnership to include European participants. In addition to the technical objectives, participation in their cultural and engineering practice events is also planned, which will enable a better understanding of the driving force for engineering research and education in European countries.

worked in design, research and consulting for eight years in China before
starting his Ph.D. program in 1994. Following the completion of his Ph.D.
degree, he worked as a project engineer for Law Engineering, Inc. 1998-1999,
and as a research associate for Georgina Tech 1999-2000. From 2000 to 2005,
Dr. Wang workeds as an assistant professor jointly appointed between Louisiana
State University and Southern University. Since 2005 he has been working as an
associate professor at Virginia Tech.
