It was reported the ratio of damages of the pavement on the steel deck was higher than that on the concrete deck in Hanshin express way. So, the damages on the steel deck were analyzed from results of daily inspection and periodic inspection, and considered by the traffic volume and aging years. As a result, the relationship between damages and aged years after paving is recognized. In addition to rutting and cracking, the possibility of recognizing the level of damages by considering the aged years of surface is shown.
