Maintenance and Restriping Strategies for Pavement Markings in Louisiana

The objective of this study is to evaluate the “Expected Service Life Method” to maintain retroreflectivity at or above the appropriate threshold in the selection and maintenance of pavement markings. To achieve this objective, a decision tree (or performance models) would be developed to determine the Pavement Marking Service Life (PMSL) based on the project conditions, including pavement marking material type, pavement type, traffic volumes, climate, marking color, etc. To facilitate the implementation of this study, an enhanced decision-making tool will be developed, which could be used by transportation agencies to determine the optimal timing for pavement marking replacement with minimal risk of under restriping or over restriping based on the specific project conditions. This tool can be envisioned as a baseline for transportation agencies to meet the minimum levels of retroreflectivity proposed by the Federal Highway Administration (FHWA) without incurring additional costs.
