Deterioration Characteristics of Waterborne Pavement Markings Under Different Operating Conditions

Drivers rely on pavement markings to maintain a safe road path especially during nighttime and challenging weather conditions. The objective of this study was to evaluate and model the deterioration of waterborne edge-line pavement markings in the field and to develop an accelerated laboratory-based procedure to evaluate pavement marking performance. For this study, field retroreflectivity data for the waterborne edge-line pavement markings from thirty-eight test sites were collected over twelve months in the State of Idaho. The researchers examined the correlation between the loss of retroreflectivity over time in the field in various districts with different environmental conditions. The results illustrated that there is a logarithmic relationship between retroreflectivity and age of waterborne pavement markings. In addition, pavement markings in districts subjected to higher ground snow loads deteriorated faster than those in districts with less ground snow loads. A three-wheel polisher device was used to evaluate the performance of the waterborne pavement markings in a laboratory. The retroreflectivity, color change, and durability using image analysis techniques were evaluated at different wearing cycles, and the three-wheel polisher caused gradual deterioration in retroreflectivity similar to the field. This study will benefit transportation agencies, particularly those sited in cold-weather regions, by enabling them to predict the deterioration of waterborne pavement markings and assist in the scheduling of marking maintenance projects to maximize the operational and safety benefits of the existing material.
