ASCE's 2009 Arthur M. Wellington Prize was presented to M. Emin Kutay, Ph.D., M.ASCE and Ahmet H. Aydilek, Ph.D., M.ASCE for the paper, "Seismic Effects on Moisture Transport in Asphalt Concrete," Journal of Transportation Engineering, July 2007. The paper integrates advanced microstructure characterization, computational flow dynamics modeling, and engineering mechanics of dynamic flow in asphalt concrete. In their study, Drs. Kutay and Aydilek utilized the real three-dimensional internal structures of asphalt specimens obtained from the X-ray compute tomography technique, conducted rigorous image analysis, and introduced a new parameter called dynamic permeability. The original contributions of this paper can be highly valuable for pavement engineers and researchers, as, for the first time, the moisture transport in asphalt concrete is defined under real traffic conditions.

The Arthur M. Wellington Prize is awarded to the author or authors of a paper on transportation on land, on the water, in the air or on foundations and closely related subjects.
