Research Abstract	This study examined procedures to evaluate the effect of commercial vehicles including overload on fatigue damage of highway structures. A method of classification in that load status was classified into empty, loaded and overloaded with pattern patching technique and load specifications was proposed. The classified vehicle load data was applied a fatigue damage model. Percentage of fatigue damage caused by each load status was calculated.
