Pavement markings provide drivers with important information about their position within their own lane. The development of a pavement deterioration estimating model has been needed for road administrator to appropriately achieve asset management, so that the life cycle cost of pavements can be minimized in long term. This study purpose was to develop pavement deterioration rate curves for road edge line markings. To accomplish these purpose, this study investigated the photo to take measurements on 200 samples based on road surface data collected from selected sections under arterial road in Chiba prefecture. In this study, the pavement performances of road edge line are described by the paint stripping ratios are modeled by segmented regression model. Then, in order to estimate paint stripping ratio, models were developed as a function of key performance variable which is the pavement over time. As the results, road edge line pavement markings should be painted at least once seven years.
