Base on Korean design code, previous design code had not considered the effect of pavement on the orthotropic steel deck, however recent design code(Limit State Design Method, 2012) allowed to consider the effect of pavement on the orthotropic steel deck, and efforts to apply the stiffness of pavement to the deck continue. Meanwhile, research on the effect of ultra thin bridge deck overlay on the orthotropic steel deck is inadequate, previous study was limited in about fatigue stress and performance between pavement layer and the orthotropic steel deck. In this study, according to changing of pavement layer stiffness application, pavement materials, pavement thickness and steel deck thickness, analysis of shear stress. In addition to base on this result, consider effectiveness of ultra-thin pavement stiffness application on the orthotropic steel deck.
